Pester的Invoke-Pester居住在哪里？

Question

根据本文档 ，应该可以使用Pester测量代码覆盖率。

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.

阅读此文档后 ，很明显，在运行Invoke-Pester之前需要导入Pester模块。

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
