If you are the author of a PowerShell module, you can use the built-in debugging tools in Microsoft Visual Studio Code to debug your script modules. In this video, we'll build a simple PowerShell script module, and then use the Pester unit testing module to write some failing tests. Then, we'll set a breakpoint in our module and break into the debugger when we execute the Pester unit tests. Once execution is paused, we'll step through the module code line by line, to discover where things are going wrong. We'll then fix the module code, and ensure that our Pester unit tests are passing.
