Pester 6: run an assertion over every item. 1,2,3 | Should-All { $_ | Should-BeGreaterThan 0 }. A nested Should failure counts as that item failing, and Pester tells you which one. #pspester #powershell

Pester 6: Should-BeCollection compares by contents and ignores the concrete type, so an object[] and a List[int] with the same items are equal. Or check only the size with -Count 3. #pspester #powershell

New in Pester 6.1: drop a Pester.BeforeContainer.ps1 at your repo root and Pester dot-sources it into every test file before it runs. Handy for parallel runs that start from clean runspaces. #pspester #powershell
