Instead of taking weeks or months to procure servers, and manually install and configure them to get them ready for software deployments, we move toward virtualization and the software-defined datacenter. One way of interpreting DevOps is simply taking the best agile practices and applying them to the IT side of things. I’m sure you have heard about “DevOps” at some point in the last few years. Traditional IT practices just can’t keep up with the pace of agile software development. Because Pester tests are simply PowerShell code, this means that you can use Pester to test all of these things, even if they’re not actually written in PowerShell. With Export-ODataEndpointProxy, New-WebServiceProxy, Invoke-WebRequest, and Invoke-RestMethod, you can interact with web APIs. With a bit more work, you can also interact with lower-level native code (such as Win32 API). From a PowerShell script, you can easily access the. One of the coolest things about PowerShell is that it can act as a “glue language” between other technologies. Have you heard of agile software development? This is part of that approach. This allows you to release code much more frequently and to detect and fix errors much earlier in the process (where it tends to be less expensive). Although it takes some time investment to write and maintain all of these automated tests, you more than make up for it by getting through the test process faster and without human interaction.

If the code passes all of the automated tests, it becomes eligible for additional manual testing (if desired), and it is then a release candidate for production. The idea is that every time someone checks in a new piece of code to source control, it is automatically put through a series of tests (which are also in source control, along with the code being tested). One of the core practices used in successful DevOps shops is automated testing (which is part of the larger practice of continuous delivery). That’s a more involved question if you’re new to DevOps in general. It provides a language that allows you to define test cases, and the Invoke-Pester cmdlet to execute these tests and report the results. Pester is a test framework for PowerShell.
