pester

问题 Does anyone have an example of mocking a dot-sourced class function with Pester 5 and PowerShell 7? Thank you. Edit: example Classes\MyClass.ps1: class MyClass { [void] Run() { Write-Host "Class: Invoking run..." } } MyModule.psm1: # Import classes . '.\Classes\MyClass.ps1' # Instantiate classes $MyClass = [MyClass]::new() # Call class function $MyClass.Run() 回答1: Pester only mocks commands - not classes or their methods. The easiest way to "mock" a PowerShell class for method dispatch

问题 Problem When a Hashtable is used as input for Should , Pester outputs only the typename instead of the content: Describe 'test' { It 'test case' { $ht = @{ foo = 21; bar = 42 } $ht | Should -BeNullOrEmpty } } Output: Expected $null or empty, but got @(System.Collections.Hashtable). Expected output like: Expected $null or empty, but got @{ foo = 21; bar = 42 }. Cause Looking at Pester source, the test input is formatted by private function Format-Nicely , which just casts to String if the

问题 By default, the output in the pipeline is hidden,But sometimes I really want to know the output at that time. Of course, I knew I could add additional commands, such as write-host or out-default. But does Pester itself have a mechanism to make the output display properly? I checked the help document and didn't find the relevant content, so I came here for help. 回答1: It is possible to write a custom Should wrapper (proxy) using this technique. The wrapper can write the pipeline objects to the

问题 I am having an issue trying to mock a powershell 5 class method, when executing the test, I get the error " CommandNotFoundException: Could not find Command FunctionToMock". I am trying to unit test the "OutputToOverwrite" method by mocking "FunctionToMock". I think I would have to mock ChocoClass itself first, but I am not sure how to do it. Thanks. Class ChocoClass { [string] OutputToOverwrite() { return $this.FunctionToMock() } [string] FunctionToMock() { return "This text will be replaced

问题 I'm trying to create a wrapper (proxy) for Pester's Should cmdlet. Possible use cases include transparent logging of test input even in case of success and improve the way Pester logs objects of certain types, e. g. hashtable. As Should is an advanced function, forwarding arguments via $args splatting does not work. So I tried to generate a wrapper using System.Management.Automation.ProxyCommand::Create() , as described by this answer: $cmd = Get-Command Should $wrapperSource = [System

问题 I'm trying to figure out how to have Pester test for parameters that are missing: Find-Waldo.Tests.ps1 $here = Split-Path -Parent $MyInvocation.MyCommand.Path $sut = (Split-Path -Leaf $MyInvocation.MyCommand.Path) -replace '\.Tests\.', '.' Describe 'Mandatory paramters' { it 'ComputerName' { { $Params = @{ #ComputerName = 'MyPc' ScriptName = 'Test' } . "$here\$sut" @Params } | Should throw } } Find-Waldo.ps1 Param ( [Parameter(Mandatory)] [String]$ComputerName, [String]$ScriptName ) Function
