Pester 6 catches a classic bug: -ForEach with an empty array used to skip silently. Now it fails discovery, so tests that never ran do not look green. Opt out with -AllowNullOrEmptyForEach. #pspester #powershell

Pester 6: assert on speed. { Start-Sleep -Milliseconds 100 } | Should-BeFasterThan 1s. Time literals like 1s and 50ms just work, and Should-BeSlowerThan is the opposite. #pspester #powershell

Pester 6: check your function's public contract. Get-Command My-Func | Should-HaveParameter Name -Type ([string]) -Mandatory. It reads the real parameter metadata: type, mandatory, default, alias, set. #pspester #powershell

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
