.Synopsis Template for creating DSC Resource Unit Tests .DESCRIPTION To Use: 1. Copy to \Tests\Unit\ folder and rename <ResourceName>.tests.ps1 (e.g. MSFT_xFirewall.tests.ps1) 2. Customize TODO sections. .NOTES Code in HEADER and FOOTER regions are standard and may be moved into DSCResource.Tools in Future and therefore should not be altered if possible. #> # TODO: Customize these parameters... $script:DSCModuleName = '<ModuleName>' # Example xNetworking $script:DSCResourceName = '<ResourceName>' # Example MSFT_xFirewall # /TODO #region HEADER # Unit Test Template Version: 1.1.0 [String] $script:moduleRoot = Split-Path -Parent (Split-Path -Parent $PSScriptRoot) if ( (-not (Test-Path -Path (Join-Path -Path $script:moduleRoot -ChildPath 'DSCResource.Tests'))) -or ` (-not (Test-Path -Path (Join-Path -Path $script:moduleRoot -ChildPath 'DSCResource.Tests\TestHelper.psm1'))) ) { & git @('clone','https://github.com/PowerShell/DscResource.Tests.git',(Join-Path -Path $script:moduleRoot -ChildPath '\DSCResource.Tests\')) } Import-Module (Join-Path -Path $script:moduleRoot -ChildPath 'DSCResource.Tests\TestHelper.psm1') -Force $TestEnvironment = Initialize-TestEnvironment ` -DSCModuleName $script:DSCModuleName ` -DSCResourceName $script:DSCResourceName ` -TestType Unit #endregion HEADER # TODO: Other Optional Init Code Goes Here... # Begin Testing try { #region Pester Test Initialization # TODO: Optionally create any variables here for use by your tests # See https://github.com/PowerShell/xNetworking/blob/dev/Tests/Unit/MSFT_xDhcpClient.Tests.ps1 # Mocks that should be applied to all cmdlets being tested may # also be created here if required. #endregion Pester Test Initialization # TODO: Common DSC Resource describe block structure # The following three Describe blocks are included as a common test pattern. # If a different test pattern would be more suitable, then test describe blocks # may be completely replaced. The goal of this pattern should be to describe # the potential states a system could be in so that the get/test/set cmdlets # can be tested in those states. Any mocks that relate to that specific state # can be included in the relevant describe block. For a more detailed description # of this approach please review https://github.com/PowerShell/DscResources/issues/143 # Add as many of these example 'states' as required to simulate the scenarions that # the DSC resource is designed to work with, below a simple "is in desired state" and # "is not in desired state" are used, but there may be more complex combinations of # factors, depending on how complex your resource is. #region Example state 1 Describe 'The system is not in the desired state' { #TODO: Mock cmdlets here that represent the system not being in the desired state #TODO: Create a set of parameters to test your get/test/set methods in this state $testParameters = @{ Property1 = 'value' Property2 = 'value' } #TODO: Update the assertions below to align with the expected results of this state It 'Get method returns something' { Get-TargetResource @testParameters | Should Be 'something' } It 'Test method returns false' { Test-TargetResource @testParameters | Should be $false } It 'Set method calls Demo-CmdletName' { Set-TargetResource @testParameters #TODO: Assert that the appropriate cmdlets were called Assert-MockCalled Demo-CmdletName } } #endregion Example state 1 #region Example state 2 Describe 'The system is in the desired state' { #TODO: Mock cmdlets here that represent the system being in the desired state #TODO: Create a set of parameters to test your get/test/set methods in this state $testParameters = @{ Property1 = 'value' Property2 = 'value' } #TODO: Update the assertions below to align with the expected results of this state It 'Get method returns something' { Get-TargetResource @testParameters | Should Be 'something' } It 'Test method returns true' { Test-TargetResource @testParameters | Should be $true } } #endregion Example state 1 #region Non-Exported Function Unit Tests # TODO: Pester Tests for any non-exported Helper Cmdlets # If the resource does not contain any non-exported helper cmdlets then # this block may be safetly deleted.
