This does mean it will require additional time to create and maintain the tests. It is important to understand using Pester is an investment to increase the code quality. Pester integrates nicely with TFS (Team Foundation Server), Azure, Github, Jenkins, and other CI servers, allowing you to fully automate your development lifecycle.įor more information please visit: Pester - The ubiquitous test and mock framework for PowerShell) Adding Pester tests to PowerShell code will enhance code quality and allows you to start creating predictable changes.

This blog post will provide some guidance and pointers how to use Pester in the Azure DevOps pipelines. By using Pester the quality of the produced PowerShell code can be increased, which will result in a higher success rate of the DevOps pipeline. In the EUC environments, PowerShell is the primary scripting language to get these deployments automated. To learn a little more about Pester and how to write tests for PowerShell, let's take a simple piece of code and write a couple of tests for it.With the increase in Azure DevOps usage, more and more EUC environments are being deployed using pipelines.

Software testing is all about writing code to verify code. That we IT pros started writing code that our companies depend on. Software developers and testers have been writing tests for code for decades now, but it hasn't been until recently If you're an IT professional and write PowerShell scripts today, you might not be familiar with the term "software testing". As you begin to depend on your PowerShell scripts for more important tasks, you'll discover that building tests for those scripts become necessary.
