function New-Fixture { <# .SYNOPSIS This function generates two scripts, one that defines a function and another one that contains its tests. .DESCRIPTION This function generates two scripts, one that defines a function and another one that contains its tests. The files are by default placed in the current directory and are called and populated as such: The script defining the function: .\Clean.ps1: function Clean { } The script containg the example test .\Clean.Tests.ps1: $here = Split-Path -Parent $MyInvocation.MyCommand.Path $sut = (Split-Path -Leaf $MyInvocation.MyCommand.Path).Replace(".Tests.", ".") . "$here\$sut" Describe "Clean" { It "does something useful" { $false | Should Be $true } } .PARAMETER Name Defines the name of the function and the name of the test to be created. .PARAMETER Path Defines path where the test and the function should be created, you can use full or relative path. If the parameter is not specified the scripts are created in the current directory. .EXAMPLE New-Fixture -Name Clean Creates the scripts in the current directory. .EXAMPLE New-Fixture C:\Projects\Cleaner Clean Creates the scripts in the C:\Projects\Cleaner directory. .EXAMPLE New-Fixture Cleaner Clean Creates a new folder named Cleaner in the current directory and creates the scripts in it. .LINK Describe Context It about_Pester about_Should #> param ( [String]$Path = $PWD, [Parameter(Mandatory=$true)] [String]$Name ) #region File contents #keep this formatted as is. the format is output to the file as is, including indentation $scriptCode = "function $name {`r`n`r`n}" $testCode = '$here = Split-Path -Parent $MyInvocation.MyCommand.Path $sut = (Split-Path -Leaf $MyInvocation.MyCommand.Path) -replace ''\.Tests\.'', ''.'' .
