I am going to show a configuration with a very simple file resource and write a Pester test to ensure that the applied configuration matches the desired configuration. It will describe an assertion or the expected result for a given test.įor DSC, there are a few uses for Pester testing. An example of this may be, “These tests examine Configuration X when Y condition is present.” If the Describe block contains a grouping of tests for a single function, then the Context block may break down the tests further.

The Context block contains a grouping of tests at the next level.

This may be as simple as, “These tests examine Configuration X.” The Describe block contains a grouping of tests at the highest level.A Pester test layout contains one or more Describe blocks, one or more Context blocks, and one or more It blocks. DSC’s layout contains a Configuration block, one or more Node blocks, and one or more Resource blocks. dotCover calculates and reports statement-level code coverage in applications targeting. Make sure you know to what extent your code is covered with unit tests.

Like DSC, Pester has a hierarchical layout. NET unit test runner and code coverage tool that integrates with Visual Studio and JetBrains Rider. This page contains the changelog for both PowerShell Tools for Visual Studio and PowerShell Pro Tools for Visual Studio. Enter a name for the project if you dont want to use the default name, and then choose Create. On the Create a new project page, type web test into the search box, and then select the Web Performance and Load Test Project Deprecated template for C. In simple terms, it provides its own language for describing what a test should do. On the start window, choose Create a new project. According to the documentation, Pester consists of a simple set of functions that exposes a testing domain-specific language (DSL) for isolating, running, evaluating, and reporting the results of PowerShell commands.

It is also available for download from the PowerShell Gallery for WMF 5.0. Pester is a testing framework, which is built into WMF 5.1. What was odd, is that the console version of the Visual Studio test runner was able to find the unit tests. Building a Pester test alongside the configuration ensures that your configuration does exactly what you need it to do. Earlier versions use something called .VSTestIntegration for the Visual Studio integration. If a configuration does not work as expected, you may have some complex troubleshooting to do.

Large DSC configurations also become harder to test. As your DSC knowledge increases, you build larger and more complex configurations. Desired State Configuration (DSC) is an awesome configuration management tool built into the most recent versions of PowerShell.
