The function I wrote has a Path parameter. It would be nice at some point to modify the function to be able to handle both XML formats.

If you want to try your hand at the challenge first, stop reading now. SAPIENs PowerShell Studio and PrimalScript products both include integrated Pester testing. I have added a metadata header, but otherwise I think this is a pretty good recreation. The challenge was to write a PowerShell command that could take the XML file and recreate this output as much as possible. Invoke-Pester C:\scripts\1 -OutputFile d:\temp\results.xml -OutputFormat JUnitXml Pester was originally designed to build unit tests around PowerShell scripts but since it was built in PowerShell, many system administrators have adapted it to performing integration or infrastructure tests in a variety of different circumstances such as routine checks, part of larger automation scripts, or part of build and release pipelines.
ManageEngine ADManager Plus - Download Free Trial $Number = Get-Random -Maximum $Features.Manage and Report Active Directory, Exchange and Microsoft 365 with # We are testing multiples so we need at least 2 # Generate 10 TestCases of a random number of Features Why Pester does not mock a cmdlet with two parameters 10.
I can then mock Get-SQLDiagRecommendations inside a BeforeAll code block using Describe "Get-SQLDiagFix" -Tags Build, Unit, Fix Ĭompare-Object (Get-SQLDiagFix -Product $Product -Feature $Feature) $results | Should BeNullOrEmpty Using Pester to test a PowerShell module, my mocked function doesnt return a value. I did this by creating a json file from the API and saving it in a json folder inside the tests folder This is the command that each of the current available commands in the module use to get the recommendations from the SQL Server Diagnostic Recommendations API. Pester can also run on older systems as well by downloading a copy from the PowerShell Gallery or downloading from Github.
Pester is an open source project that's built as a PowerShell module that comes pre-installed with Windows 10 and Windows Server 2016. In my describe block for each function I mock Get-SQLDiagRecommendations. For testing PowerShell code, the de facto testing framework is Pester. Pester will soon be integrated into PowerShell 5.0, at which point there is no longer any excuse. It allows robust and flexible means of testing PowerShell code, just as NUnit and similar tools do for compiled.
This is how I wrote the Pester tests for that command Mocking the results Pester is a community-driven BDD Unit Test framework for PowerShell.
I can use pester successfully but I can't get any debug output from the tests - only the test report. I'm using pester (v5) to test my cmdlets and will have a lot of test cases for the many scenarios that I want to test.

If you have PowerShell version 5 then you will have Pester already installed although you should update it to the latest version. Pester consists of a simple set of functions that expose a testing domain-specific language (DSL) for isolating, running, evaluating and reporting the results of PowerShell commands Pester provides a framework for running unit tests to execute and validate PowerShell commands from within PowerShell. Pester is a PowerShell module for Test Driven Development Whilst writing Get-SQLDiagFix I wrote some Pester Tests to make sure that the output from the code was as expected. I blogged about how I used Pester to develop one of the functions. I have written a module SQLDiagAPI for consuming the SQL Server Diagnostics API with PowerShell.
