Not testing your infrastructure can be catastrophic. Learn how to prevent disaster and properly test your PowerShell and infrastructure with Pester.

Writing a small script, waiting to see if it errors out and then eyeballing the results are common. But are you sure that script you created actually did everything you intended? It's important to understand just because a script doesn't output an error and your manual eyeballing sees no problems doesn't actually mean there isn't one. In this course, Infrastructure Testing with Pester 3, you'll go from guessing the infrastructure changes that you made to seeing if they did actually change. First, you'll discover how to write the right tests. Next, you'll explore the infrastructure dependencies. Finally, you'll learn how to build a web dashboard. By the end of this course, you'll have a better understanding on infrastructure testing with Pester.
