2. Setup Your Environment
1. Ensure you are set for organizational deployment
Please see the organizational deployment guide
2. Get the package into your environment
Option 1: Cached Package (Unreliable, Requires Internet - Same As Community)-
Open Source or Commercial:
- Proxy Repository - Create a proxy nuget repository on Nexus, Artifactory Pro, or a proxy Chocolatey repository on ProGet. Point your upstream to https://community.chocolatey.org/api/v2/. Packages cache on first access automatically. Make sure your choco clients are using your proxy repository as a source and NOT the default community repository. See source command for more information.
- You can also just download the package and push it to a repository Download
-
Open Source
-
Download the package:
Download - Follow manual internalization instructions
-
-
Package Internalizer (C4B)
-
Run: (additional options)
choco download pscodehealth --internalize --version=0.2.9 --source=https://community.chocolatey.org/api/v2/ -
For package and dependencies run:
choco push --source="'INTERNAL REPO URL'" - Automate package internalization
-
Run: (additional options)
3. Copy Your Script
choco upgrade pscodehealth -y --source="'INTERNAL REPO URL'" --version="'0.2.9'" [other options]See options you can pass to upgrade.
See best practices for scripting.
Add this to a PowerShell script or use a Batch script with tools and in places where you are calling directly to Chocolatey. If you are integrating, keep in mind enhanced exit codes.
If you do use a PowerShell script, use the following to ensure bad exit codes are shown as failures:
choco upgrade pscodehealth -y --source="'INTERNAL REPO URL'" --version="'0.2.9'"
$exitCode = $LASTEXITCODE
Write-Verbose "Exit code was $exitCode"
$validExitCodes = @(0, 1605, 1614, 1641, 3010)
if ($validExitCodes -contains $exitCode) {
Exit 0
}

Package Approved
This package was approved by moderator gep13 on 11 May 2018.
Description
PSCodeHealth allows you to measure the quality and maintainability of your PowerShell code, based on a variety of metrics related to:
- Code length
- Code complexity
- Code smells, styling issues and violations of best practices
- Tests and test coverage
- Comment-based help
It can allow you to ensure that your code is compliant with metrics goals (quality gates). You can use the default (built-in) compliance rules, and you can also customize some (or all) compliance rules to fit your goals.
These features can be leveraged from within your PowerShell release pipeline.
PSCodeHealth can also generate a highly visual HTML report so that you can interpret the results at a glance, and easily share them.
NOTE: This is an automatically updated package. If you find it is out of date by more than a week, please contact the maintainer(s) and let them know the package is no longer updating correctly.

.SYNOPSIS
Creates a new custom object and gives it the TypeName : 'PSCodeHealth.Compliance.Result'.
.DESCRIPTION
Creates a new custom object based on a PSCodeHealth.Compliance.Rule object and a compliance result, and gives it the TypeName : 'PSCodeHealth.Compliance.Result'.
.PARAMETER ComplianceRule
The compliance rule which was evaluated.
.PARAMETER Value
The value from the health report for the evaluated metric.
.PARAMETER Result
The compliance result, based on the compliance rule and the actual value from the health report.
.PARAMETER FunctionName
To get compliance results for a specific function.
If this parameter is specified, this creates a PSCodeHealth.Compliance.FunctionResult object, instead of PSCodeHealth.Compliance.Result.
.EXAMPLE
PS C:\> New-PSCodeHealthComplianceResult -ComplianceRule $Rule -Value 81.26 -Result Warning
Returns new custom object of the type PSCodeHealth.Compliance.Result.
.EXAMPLE
PS C:\> New-PSCodeHealthComplianceResult -ComplianceRule $Rule -Value 81.26 -Result Warning -FunctionName 'Get-Something'

Creates a new custom object and gives it the TypeName : 'PSCodeHealth.Overall.HealthReport'.
.DESCRIPTION
Creates a new custom object and gives it the TypeName : 'PSCodeHealth.Overall.HealthReport'.
This output object contains metrics for the code in all the PowerShell files specified via the Path parameter, uses the function health records specified via the FunctionHealthRecord parameter.
The value of the TestsPath parameter specifies the location of the tests when calling Pester to generate test coverage information.
.PARAMETER ReportTitle
To specify the title of the health report.
This is mainly used when generating an HTML report.
.PARAMETER AnalyzedPath
To specify the code path being analyzed.
This corresponds to the original Path value of Invoke-PSCodeHealth.
.PARAMETER Path
To specify the path of one or more PowerShell file(s) to analyze.
.PARAMETER FunctionHealthRecord
To specify the PSCodeHealth.Function.HealthRecord objects which will be the basis for the report.
.PARAMETER TestsPath
To specify the file or directory where the Pester tests are located.
If a directory is specified, the directory and all subdirectories will be searched recursively for tests.
.PARAMETER TestsResult
To use an existing Pester tests result object for generating the following metrics :
- NumberOfTests
- NumberOfFailedTests
- FailedTestsDetails
- NumberOfPassedTests
- TestsPassRate (%)
- TestCoverage (%)
- CommandsMissedTotal
.EXAMPLE
PS C:\> New-PSCodeHealthReport -ReportTitle 'MyTitle' -AnalyzedPath 'C:\Folder' -Path $MyPath -FunctionHealthRecord $FunctionHealthRecords -TestsPath "$MyPath\Tests"
Returns new custom object of the type PSCodeHealth.Overall.HealthReport, containing metrics for the code in all the PowerShell files in $MyPath, using the function health records in $FunctionHealthRecords and running all tests in "$MyPath\Tests" (and its subdirectories) to generate test coverage information.

Function Get-PSCodeHealthComplianceRule {
<#
.SYNOPSIS
Get the PSCodeHealth compliance rules (metrics thresholds, etc...) which are currently in effect.
.DESCRIPTION
Get the PSCodeHealth compliance rules (metrics warning and fail thresholds, etc...) which are currently in effect.
By default, all the compliance rules are coming from the file PSCodeHealthSettings.json in the module root.
Custom compliance rules can be specified in JSON format in a file, via the parameter CustomSettingsPath.
In this case, any compliance rules specified in the custom settings file override the default, and rules not specified in the custom settings file will use the defaults from PSCodeHealthSettings.json.
By default, this function outputs compliance rules for every metrics in every settings groups, but this can filtered via the MetricName and the SettingsGroup parameters.
.PARAMETER CustomSettingsPath
To specify the path of a file containing user-defined compliance rules (metrics thresholds, etc...) in JSON format.
Any compliance rule specified in this file override the default, and rules not specified in this file will use the default from PSCodeHealthSettings.json.
.PARAMETER SettingsGroup
To filter the output compliance rules to only the ones located in the specified group.
There are 2 settings groups in PSCodeHealthSettings.json, so there are 2 possible values for this parameter : 'PerFunctionMetrics' and 'OverallMetrics'.
Metrics in the PerFunctionMetrics group are generated for each individual function and metrics in the OverallMetrics group are calculated for the entire file or folder specified in the 'Path' parameter of Invoke-PSCodeHealth.
If not specified, compliance rules from both groups are output.
.PARAMETER MetricName
To filter the output compliance rules to only the ones for the specified metric or metrics.
There is a large number of metrics, so for convenience, all the possible values are available via tab completion.
.EXAMPLE
PS C:\> Get-PSCodeHealthComplianceRule
Gets all the default PSCodeHealth compliance rules (metrics warning and fail thresholds, etc...).
.EXAMPLE
PS C:\> Get-PSCodeHealthComplianceRule -CustomSettingsPath .\MySettings.json -SettingsGroup OverallMetrics
Gets all PSCodeHealth compliance rules (metrics warning and fail thresholds, etc...) in effect in the group 'OverallMetrics'.
This also output any compliance rule overriding the defaults because they are specified in the file MySettings.json.
.EXAMPLE
PS C:\> Get-PSCodeHealthComplianceRule -MetricName 'TestCoverage','Complexity','MaximumNestingDepth'
Gets the default compliance rules in effect for the TestCoverage, Complexity and MaximumNestingDepth metrics.
In the case of TestCoverage, this metric exists in both PerFunctionMetrics and OverallMetrics, so the TestCoverage compliance rules from both groups will be output.
.OUTPUTS
PSCodeHealth.Compliance.Rule

Function Invoke-PSCodeHealth {
<#
.SYNOPSIS
Gets quality and maintainability metrics for PowerShell code contained in scripts, modules or directories.
.DESCRIPTION
Gets quality and maintainability metrics for PowerShell code contained in scripts, modules or directories.
These metrics relate to :
- Length of functions
- Complexity of functions
- Code smells, styling issues and violations of best practices (using PSScriptAnalyzer)
- Tests and test coverage (using Pester to run tests)
- Comment-based help in functions
.PARAMETER Path
To specify the path of the directory to search for PowerShell files to analyze.
If the Path is not specified and the current location is in a FileSystem PowerShell drive, this will default to the current directory.
.PARAMETER TestsPath
To specify the file or directory where tests are located.
If not specified, the command will look for tests in the same directory as each function.
.PARAMETER TestsResult
To use an existing Pester tests result object for generating the following metrics :
- NumberOfTests
- NumberOfFailedTests
- NumberOfPassedTests
- TestsPassRate (%)
- TestCoverage (%)
- CommandsMissedTotal
.PARAMETER Recurse
To search PowerShell files in the Path directory and all subdirectories recursively.
.PARAMETER Exclude
To specify file(s) to exclude from both the code analysis point of view and the test coverage point of view.
The value of this parameter qualifies the Path parameter.
Enter a path element or pattern, such as *example*. Wildcards are permitted.
.PARAMETER HtmlReportPath
To instruct Invoke-PSCodeHealth to generate an HTML report, and specify the path where the HTML file should be saved.
The path must include the folder path (which has to exist) and the file name.
.PARAMETER CustomSettingsPath
To specify the path of a file containing user-defined compliance rules (metrics thresholds, etc...) in JSON format.
Any compliance rule specified in this file override the default, and rules not specified in this file will use the default from PSCodeHealthSettings.json.
.PARAMETER PassThru
When the parameter HtmlReportPath is used, by default, Invoke-PSCodeHealth doesn't output a [PSCodeHealth.Overall.HealthReport] object to the pipeline.
The PassThru parameter allows to instruct Invoke-PSCodeHealth to output both an HTML report file and a [PSCodeHealth.Overall.HealthReport] object.
.EXAMPLE
PS C:\> Invoke-PSCodeHealth -Path 'C:\GitRepos\MyModule' -Recurse -TestsPath 'C:\GitRepos\MyModule\Tests\Unit'
Gets quality and maintainability metrics for code from PowerShell files in the directory C:\GitRepos\MyModule\ and any subdirectories.
This command will look for tests located in the directory C:\GitRepos\MyModule\Tests\Unit, and any subdirectories.
.EXAMPLE
PS C:\> Invoke-PSCodeHealth -Path 'C:\GitRepos\MyModule' -TestsPath 'C:\GitRepos\MyModule\Tests' -Recurse -Exclude "*example*"
Gets quality and maintainability metrics for code from PowerShell files in the directory C:\GitRepos\MyModule\ and any subdirectories, except for files containing "example" in their name.
This command will look for tests located in the directory C:\GitRepos\MyModule\Tests\, and any subdirectories.
.EXAMPLE
PS C:\> Invoke-PSCodeHealth -Path 'C:\GitRepos\MyModule' -TestsPath 'C:\GitRepos\MyModule\Tests' -HtmlReportPath .\Report.html -PassThru
Gets quality and maintainability metrics for code from PowerShell files in the directory C:\GitRepos\MyModule\.
This command will create an HTML report (Report.html) in the current directory and a PSCodeHealth.Overall.HealthReport object to the pipeline.
The styling of HTML elements will reflect their compliance, based on the default compliance rules.
.EXAMPLE
PS C:\> Invoke-PSCodeHealth -Path 'C:\GitRepos\MyModule' -TestsPath 'C:\GitRepos\MyModule\Tests' -HtmlReportPath .\Report.html -CustomSettingsPath .\MySettings.json
Gets quality and maintainability metrics for code from PowerShell files in the directory C:\GitRepos\MyModule\.
This command will create an HTML report (Report.html) in the current directory and a PSCodeHealth.Overall.HealthReport object to the pipeline.
The styling of HTML elements will reflect their compliance, based on the default compliance rules and any custom rules in the file .\MySettings.json.

<#
.SYNOPSIS
Gets the compliance result(s) of the analyzed PowerShell code, based on a PSCodeHealth report and compliance rules contained in PSCodeHealth settings.
.DESCRIPTION
Gets the compliance result(s) of the analyzed PowerShell code, based on a PSCodeHealth report and compliance rules contained in PSCodeHealth settings.
The values in the input PSCodeHealth report will be checked for compliance against the rules in the PSCodeHealth settings which are currently in effect.
By default, all compliance rules are coming from the file PSCodeHealthSettings.json in the module root. Custom compliance rules can be specified in JSON format in a file, via the parameter CustomSettingsPath.
The possible compliance levels are :
- Pass
- Warning
- Fail
By default, this function outputs the compliance results for every metrics in every settings groups, but this can filtered via the MetricName and the SettingsGroup parameters.
.PARAMETER HealthReport
The PSCodeHealth report (object of the type PSCodeHealth.Overall.HealthReport) to analyze for compliance.
The ouput of the command Invoke-PSCodeHealth is a PSCodeHealth report and can be bound to this parameter via pipeline input.
.PARAMETER CustomSettingsPath
To specify the path of a file containing user-defined compliance rules (metrics thresholds, etc...) in JSON format.
Any compliance rule specified in this file override the default, and rules not specified in this file will use the default from PSCodeHealthSettings.json.
.PARAMETER SettingsGroup
To evaluate compliance only for the metrics located in the specified group.
There are 2 settings groups in PSCodeHealthSettings.json, so there are 2 possible values for this parameter : 'PerFunctionMetrics' and 'OverallMetrics'.
Metrics in the PerFunctionMetrics group are for each individual function and metrics in the OverallMetrics group are for the entire file or folder specified in the 'Path' parameter of Invoke-PSCodeHealth.
If not specified, compliance is evaluated for metrics in both groups.
.PARAMETER MetricName
To get compliance results only for the specified metric(s).
There is a large number of metrics, so for convenience, all the possible values are available via tab completion.
If not specified, compliance is evaluated for all metrics.
.PARAMETER FunctionName
To get compliance results for a specific function.
This is a dynamic parameter which is available when the specified HealthReport contains at least 1 FunctionHealthRecords.
.PARAMETER Summary
To output a single overall compliance result based on all the evaluated metrics.
This retains the worst compliance level, meaning :
- If any evaluated metric has the 'Fail' compliance level, the overall result is 'Fail'
- If any evaluated metric has the 'Warning' compliance level and none has 'Fail', the overall result is 'Warning'
- If all evaluated metrics has the 'Pass' compliance level, the overall result is 'Pass'
.EXAMPLE
PS C:\> Test-PSCodeHealthCompliance -HealthReport $MyProjectHealthReport
Gets the compliance results for every metrics, based on the specified PSCodeHealth report ($MyProjectHealthReport) and the compliance rules in the default settings.
.EXAMPLE
PS C:\> Invoke-PSCodeHealth | Test-PSCodeHealthCompliance
Gets the compliance results for every metrics, based on the PSCodeHealth report specified via pipeline input and the compliance rules in the default settings.
.EXAMPLE
PS C:\> Test-PSCodeHealthCompliance -HealthReport $MyProjectHealthReport -CustomSettingsPath .\MySettings.json -SettingsGroup OverallMetrics
Evaluates the compliance results for the metrics in the settings group OverallMetrics, based on the specified PSCodeHealth report ($MyProjectHealthReport).
This checks compliance against compliance rules in the defaults compliance rules and any custom compliance rule from the file 'MySettings.json'.
.EXAMPLE
PS C:\> Test-PSCodeHealthCompliance -HealthReport $MyProjectHealthReport -MetricName 'TestCoverage','Complexity','MaximumNestingDepth'
Evaluates the compliance results only for the TestCoverage, Complexity and MaximumNestingDepth metrics.
In the case of TestCoverage, this metric exists in both PerFunctionMetrics and OverallMetrics, so this evaluates the compliance result for the TestCoverage metric from both groups.
.EXAMPLE
PS C:\> Test-PSCodeHealthCompliance -HealthReport $MyProjectHealthReport -FunctionName 'Get-Something'
Evaluates the compliance results specifically for the function Get-Something. Because this is the compliance of a specific function, only the per function metrics are evaluated.
If the value of the FunctionName parameter doesn't match any function name in the HealthReport the parameter validation will fail and state the set of possible values.
.EXAMPLE
PS C:\> Invoke-PSCodeHealth | Test-PSCodeHealthCompliance -Summary
Evaluates the compliance results for every metrics, based on the PSCodeHealth report specified via pipeline input and the compliance rules in the default settings.
This outputs an overall 'Fail','Warning' or 'Pass' value for all the evaluated metrics.

Function Get-PSCodeHealthComplianceRule {
<#
.SYNOPSIS
Get the PSCodeHealth compliance rules (metrics thresholds, etc...) which are currently in effect.
.DESCRIPTION
Get the PSCodeHealth compliance rules (metrics warning and fail thresholds, etc...) which are currently in effect.
By default, all the compliance rules are coming from the file PSCodeHealthSettings.json in the module root.
Custom compliance rules can be specified in JSON format in a file, via the parameter CustomSettingsPath.
In this case, any compliance rules specified in the custom settings file override the default, and rules not specified in the custom settings file will use the defaults from PSCodeHealthSettings.json.
By default, this function outputs compliance rules for every metrics in every settings groups, but this can filtered via the MetricName and the SettingsGroup parameters.
.PARAMETER CustomSettingsPath
To specify the path of a file containing user-defined compliance rules (metrics thresholds, etc...) in JSON format.
Any compliance rule specified in this file override the default, and rules not specified in this file will use the default from PSCodeHealthSettings.json.
.PARAMETER SettingsGroup
To filter the output compliance rules to only the ones located in the specified group.
There are 2 settings groups in PSCodeHealthSettings.json, so there are 2 possible values for this parameter : 'PerFunctionMetrics' and 'OverallMetrics'.
Metrics in the PerFunctionMetrics group are generated for each individual function and metrics in the OverallMetrics group are calculated for the entire file or folder specified in the 'Path' parameter of Invoke-PSCodeHealth.
If not specified, compliance rules from both groups are output.
.PARAMETER MetricName
To filter the output compliance rules to only the ones for the specified metric or metrics.
There is a large number of metrics, so for convenience, all the possible values are available via tab completion.
.EXAMPLE
PS C:\> Get-PSCodeHealthComplianceRule
Gets all the default PSCodeHealth compliance rules (metrics warning and fail thresholds, etc...).
.EXAMPLE
PS C:\> Get-PSCodeHealthComplianceRule -CustomSettingsPath .\MySettings.json -SettingsGroup OverallMetrics
Gets all PSCodeHealth compliance rules (metrics warning and fail thresholds, etc...) in effect in the group 'OverallMetrics'.
This also output any compliance rule overriding the defaults because they are specified in the file MySettings.json.
.EXAMPLE
PS C:\> Get-PSCodeHealthComplianceRule -MetricName 'TestCoverage','Complexity','MaximumNestingDepth'
Gets the default compliance rules in effect for the TestCoverage, Complexity and MaximumNestingDepth metrics.
In the case of TestCoverage, this metric exists in both PerFunctionMetrics and OverallMetrics, so the TestCoverage compliance rules from both groups will be output.

Function Invoke-PSCodeHealth {
<#
.SYNOPSIS
Gets quality and maintainability metrics for PowerShell code contained in scripts, modules or directories.
.DESCRIPTION
Gets quality and maintainability metrics for PowerShell code contained in scripts, modules or directories.
These metrics relate to :
- Length of functions
- Complexity of functions
- Code smells, styling issues and violations of best practices (using PSScriptAnalyzer)
- Tests and test coverage (using Pester to run tests)
- Comment-based help in functions
.PARAMETER Path
To specify the path of the directory to search for PowerShell files to analyze.
If the Path is not specified and the current location is in a FileSystem PowerShell drive, this will default to the current directory.
.PARAMETER TestsPath
To specify the file or directory where tests are located.
If not specified, the command will look for tests in the same directory as each function.
.PARAMETER TestsResult
To use an existing Pester tests result object for generating the following metrics :
- NumberOfTests
- NumberOfFailedTests
- NumberOfPassedTests
- TestsPassRate (%)
- TestCoverage (%)
- CommandsMissedTotal
.PARAMETER Recurse
To search PowerShell files in the Path directory and all subdirectories recursively.
.PARAMETER Exclude
To specify file(s) to exclude from both the code analysis point of view and the test coverage point of view.
The value of this parameter qualifies the Path parameter.
Enter a path element or pattern, such as *example*. Wildcards are permitted.
.PARAMETER HtmlReportPath
To instruct Invoke-PSCodeHealth to generate an HTML report, and specify the path where the HTML file should be saved.
The path must include the folder path (which has to exist) and the file name.
.PARAMETER CustomSettingsPath
To specify the path of a file containing user-defined compliance rules (metrics thresholds, etc...) in JSON format.
Any compliance rule specified in this file override the default, and rules not specified in this file will use the default from PSCodeHealthSettings.json.
.PARAMETER PassThru
When the parameter HtmlReportPath is used, by default, Invoke-PSCodeHealth doesn't output a [PSCodeHealth.Overall.HealthReport] object to the pipeline.
The PassThru parameter allows to instruct Invoke-PSCodeHealth to output both an HTML report file and a [PSCodeHealth.Overall.HealthReport] object.
.EXAMPLE
PS C:\> Invoke-PSCodeHealth -Path 'C:\GitRepos\MyModule' -Recurse -TestsPath 'C:\GitRepos\MyModule\Tests\Unit'
Gets quality and maintainability metrics for code from PowerShell files in the directory C:\GitRepos\MyModule\ and any subdirectories.
This command will look for tests located in the directory C:\GitRepos\MyModule\Tests\Unit, and any subdirectories.
.EXAMPLE
PS C:\> Invoke-PSCodeHealth -Path 'C:\GitRepos\MyModule' -TestsPath 'C:\GitRepos\MyModule\Tests' -Recurse -Exclude "*example*"
Gets quality and maintainability metrics for code from PowerShell files in the directory C:\GitRepos\MyModule\ and any subdirectories, except for files containing "example" in their name.
This command will look for tests located in the directory C:\GitRepos\MyModule\Tests\, and any subdirectories.
.EXAMPLE
PS C:\> Invoke-PSCodeHealth -Path 'C:\GitRepos\MyModule' -TestsPath 'C:\GitRepos\MyModule\Tests' -HtmlReportPath .\Report.html -PassThru
Gets quality and maintainability metrics for code from PowerShell files in the directory C:\GitRepos\MyModule\.
This command will create an HTML report (Report.html) in the current directory and a PSCodeHealth.Overall.HealthReport object to the pipeline.
The styling of HTML elements will reflect their compliance, based on the default compliance rules.
.EXAMPLE
PS C:\> Invoke-PSCodeHealth -Path 'C:\GitRepos\MyModule' -TestsPath 'C:\GitRepos\MyModule\Tests' -HtmlReportPath .\Report.html -CustomSettingsPath .\MySettings.json
Gets quality and maintainability metrics for code from PowerShell files in the directory C:\GitRepos\MyModule\.
This command will create an HTML report (Report.html) in the current directory and a PSCodeHealth.Overall.HealthReport object to the pipeline.
The styling of HTML elements will reflect their compliance, based on the default compliance rules and any custom rules in the file .\MySettings.json.

Function Test-PSCodeHealthCompliance {
<#
.SYNOPSIS
Gets the compliance result(s) of the analyzed PowerShell code, based on a PSCodeHealth report and compliance rules contained in PSCodeHealth settings.
.DESCRIPTION
Gets the compliance result(s) of the analyzed PowerShell code, based on a PSCodeHealth report and compliance rules contained in PSCodeHealth settings.
The values in the input PSCodeHealth report will be checked for compliance against the rules in the PSCodeHealth settings which are currently in effect.
By default, all compliance rules are coming from the file PSCodeHealthSettings.json in the module root. Custom compliance rules can be specified in JSON format in a file, via the parameter CustomSettingsPath.
The possible compliance levels are :
- Pass
- Warning
- Fail
By default, this function outputs the compliance results for every metrics in every settings groups, but this can filtered via the MetricName and the SettingsGroup parameters.
.PARAMETER HealthReport
The PSCodeHealth report (object of the type PSCodeHealth.Overall.HealthReport) to analyze for compliance.
The ouput of the command Invoke-PSCodeHealth is a PSCodeHealth report and can be bound to this parameter via pipeline input.
.PARAMETER CustomSettingsPath
To specify the path of a file containing user-defined compliance rules (metrics thresholds, etc...) in JSON format.
Any compliance rule specified in this file override the default, and rules not specified in this file will use the default from PSCodeHealthSettings.json.
.PARAMETER SettingsGroup
To evaluate compliance only for the metrics located in the specified group.
There are 2 settings groups in PSCodeHealthSettings.json, so there are 2 possible values for this parameter : 'PerFunctionMetrics' and 'OverallMetrics'.
Metrics in the PerFunctionMetrics group are for each individual function and metrics in the OverallMetrics group are for the entire file or folder specified in the 'Path' parameter of Invoke-PSCodeHealth.
If not specified, compliance is evaluated for metrics in both groups.
.PARAMETER MetricName
To get compliance results only for the specified metric(s).
There is a large number of metrics, so for convenience, all the possible values are available via tab completion.
If not specified, compliance is evaluated for all metrics.
.PARAMETER FunctionName
To get compliance results for a specific function.
This is a dynamic parameter which is available when the specified HealthReport contains at least 1 FunctionHealthRecords.
.PARAMETER Summary
To output a single overall compliance result based on all the evaluated metrics.
This retains the worst compliance level, meaning :
- If any evaluated metric has the 'Fail' compliance level, the overall result is 'Fail'
- If any evaluated metric has the 'Warning' compliance level and none has 'Fail', the overall result is 'Warning'
- If all evaluated metrics has the 'Pass' compliance level, the overall result is 'Pass'
.EXAMPLE
PS C:\> Test-PSCodeHealthCompliance -HealthReport $MyProjectHealthReport
Gets the compliance results for every metrics, based on the specified PSCodeHealth report ($MyProjectHealthReport) and the compliance rules in the default settings.
.EXAMPLE
PS C:\> Invoke-PSCodeHealth | Test-PSCodeHealthCompliance
Gets the compliance results for every metrics, based on the PSCodeHealth report specified via pipeline input and the compliance rules in the default settings.
.EXAMPLE
PS C:\> Test-PSCodeHealthCompliance -HealthReport $MyProjectHealthReport -CustomSettingsPath .\MySettings.json -SettingsGroup OverallMetrics
Evaluates the compliance results for the metrics in the settings group OverallMetrics, based on the specified PSCodeHealth report ($MyProjectHealthReport).
This checks compliance against compliance rules in the defaults compliance rules and any custom compliance rule from the file 'MySettings.json'.
.EXAMPLE
PS C:\> Test-PSCodeHealthCompliance -HealthReport $MyProjectHealthReport -MetricName 'TestCoverage','Complexity','MaximumNestingDepth'
Evaluates the compliance results only for the TestCoverage, Complexity and MaximumNestingDepth metrics.
In the case of TestCoverage, this metric exists in both PerFunctionMetrics and OverallMetrics, so this evaluates the compliance result for the TestCoverage metric from both groups.
.EXAMPLE
PS C:\> Test-PSCodeHealthCompliance -HealthReport $MyProjectHealthReport -FunctionName 'Get-Something'
Evaluates the compliance results specifically for the function Get-Something. Because this is the compliance of a specific function, only the per function metrics are evaluated.
If the value of the FunctionName parameter doesn't match any function name in the HealthReport the parameter validation will fail and state the set of possible values.
.EXAMPLE
PS C:\> Invoke-PSCodeHealth | Test-PSCodeHealthCompliance -Summary
Evaluates the compliance results for every metrics, based on the PSCodeHealth report specified via pipeline input and the compliance rules in the default settings.
This outputs an overall 'Fail','Warning' or 'Pass' value for all the evaluated metrics.
