Table of Contents – Before and After Blocks

If for some reason you’re just getting here now, we’re doing chapter reviews on Adam Bertram‘s The Pester Book. Get a copy, start reading, and follow along with us. It’s the PowerShell testing framework, and you’re going to need to know it, if knowing PowerShell is something you already need to know.

Today we’re going to review a good, but short chapter on Before and After blocks. Before and After blocks contain two blocks each. Those are BeforeAll and BeforeEach, and AfterAll, and AfterEach.

BeforeAll and AfterAll blocks indicate things that should happen before any of the It blocks run, and after all the It blocks run, respectively. The difference with BeforeEach and AfterEach, is that whatever arbitrary code runs in these, does so before and after each It block, and not just once at the beginning and once at the end of a Describe and/or Context block.

Got it.
