Pester mock code#
This command is something I might integrate into a VS Code task. You might want to edit your version of the function. The function creates a here-string for each test block. Write-Verbose " Ending $($myinvocation.mycommand)" There are a lot of forum post of people having a hard time mocking some cmdlets, either it is remote cmdlets imported by a session that is not available during testing, cmdlets that are not present on the development machine or simply some built in cmdlets that are hard to mock like Import-PSSession, Invoke-Command etc. Write-Warning "No functions found in the module $Modulename or the module itself doesn't exist." Mocking the unmockable, mocking remote or unavailable cmdlets. Write-Verbose " Defining tests for $($cmd.name) $($tags ? "-tag $($tags -join ',')" : #foreach cmd $cmds = Get-Command -Module $ModuleName -CommandType Function -ErrorAction Stop Write-Verbose " Getting commands from $ModuleName" #Put blocktype in proper case to make it pretty Write-Verbose " Starting $($myinvocation.mycommand)"

I can run New-PesterBlock and pipe to Out-File or Set-Clipboard. 'PesterMockcbaa9725-8267-4c27-8605-6a94eaf92de7' which ultimately calls your mock script block, and it then generates an alias for the function you're mocking which resolves to this function. The function writes strings to the pipeline. Some edge case fixes: Run Parameter filter in the correct scope Should -Invoke inside of InModuleScope instead running it where the mock was originally run (. To implement a Mock, Pester creates a randomly-named function in the appropriate scope (e.g. If you want to use my function in Windows PowerShell, you’ll need to revise it. Note that my code for the tag insertion relies on the ternary operator from PowerShell 7. Although, I can opt for a Context block instead. Each function is wrapped in a Describe block. These are the baseline or boilerplate tests that I always want to run for each function. For each function, it creates a set of standard Pester assertions. My function takes a module and extracts all of the public exported functions. Instead, I wrote a PowerShell function to accelerate developing Pester 5.x tests. I know I could create a set of VS Code snippets, but that feels limiting and I’d have to make sure the snippets are available on all systems where I might be running VS Code. But copying and pasting code snippets is tedious. I have a standard set of tests that I like to use for functions in my module.
