PSMatcher is a test utility, that lets you easier test responses and json, when some part of the response is something out of your control (autogenerated id, guid, datetime etc).
It's here on the PowerShell Gallery

---------- ------------ ------
True NMatcher.Matching.Result
False Expected value did not appear at path id. NMatcher.Matching.Result
The matcher also checks if elements are missing or if too many are supplied.
Stay Tuned: Examples will be added showing how well this works with PowerShell objects and Hashtables.
- @string@
- @int@
- @double@
- @bool@
- @null@
- @any@
- @guid@
This wraps NMatcher. Check out that readme for more detail.
