According to this documentation it should be possible to measure code coverage using Pester.

PS C:\path\to\codeCoverage> Invoke-Pester .\CoverageTest.Tests.ps1 -CodeCoverage .\CoverageTest.ps1

Invoke-Pester : The term 'Invoke-Pester' is not recognized as the name of a cmdlet, function, script file, or operable
program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
At line:1 char:1
+ Invoke-Pester .\CoverageTest.Tests.ps1 -CodeCoverage .\CoverageTest.ps1
+ ~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (Invoke-Pester:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

阅读本文档后，很明显需要在运行之前导入 Pester 模块Invoke-Pester

PS C:\path\to\codeCoverage> Import-Module "C:\ProgramData\Chocolatey\lib\pester.3.1.1\tools\Pester.psm1"
PS C:\path\to\codeCoverage> Invoke-Pester .\CoverageTest.Tests.ps1 -CodeCoverage .\CoverageTest.ps1
