Thanks to core team member Alex Povar (@zvirja) for putting a huge amount of work into 🚀 defining and implementing features, fixes and refactoring for this release! Also thanks to @tpodolak for the new NSubstitute.Analyzers project! Finally, thanks to everyone who submitted PRs, raised or commented on issues, or took the time to help answer questions on StackOverflow.
Major new features and improvements
- [NEW] NSubstitute.Analyzers project. 🔧 Uses Roslyn to detect potential problems with NSubstitute configurations, such as trying to substitute for non-virtual members. Whenever you add NSubstitute to your C# or VB project, 📦 don't forget to also add the corresponding NSubstitute.Analyzers package! Thanks to @tpodolak for starting and running this project!
CallBasefor enabling base method calls for specific methods. (#449, @zvirja)
- [NEW][BREAKING] Arg matchers (
Arg.Isetc) can now be used for
outarguments. 👀 See [BreakingChanges.md](BreakingChanges.md) if you are still using pre-C#7. (#404, @zvirja)
- 🔧 [NEW]
NSubstitute.Extensions.ConfigurationExtensionsto 🔧 ensure NSubstitute handles the next call as a configuration/specification. (#350, @zvirja)
- 🐎 [UPDATE] Performance improvements. (@zvirja)
- Delegate proxy generation improvements (#362)
- Minimise allocations and LINQ use on hot code paths (#390)
- Optimise array allocation (#395)
- ⚡️ [UPDATE][BREAKING] Calls made with one or more argument matchers (
Arg.Any) 🔧 will no longer return previously configured results. NSubstitute will assume the call is 🔧 being configured and avoid running logic configured via previous
Returns()calls. 👀 This helps fix some problems with overlapping configurations. See #345 and [BreakingChanges.md](BreakingChanges.md) for more information. (@zvirja)
🆕 New and improved debugging, errors and error messages
- 🔧 [NEW] Raise
CouldNotConfigureBaseMethodExceptionwhen trying to configure a call to call a base method that does not exist. (#429, @zvirja)
- [NEW] Raise
RedundantArgumentMatcherExceptionif extra arg matchers are detected. This is ✅ a huge help for immediately identifying misconfigured tests. (@zvirja)
- ⚡️ [UPDATE] Improved
AmbiguousArgumentsExceptionbehaviour and errors. (#403 and others; @zvirja)
- [NEW] Improve debugging experience with proxy ids. (#39, @zvirja)
- ⚡️ [UPDATE] Improved display of
MatchArgsto help with debugging. (@zvirja)
- ✅ [NEW][BREAKING] Detection of unused argument matchers. This helps to identify errors in tests due to incorrectly used argument matchers. (#361, #89, #279; @zvirja)
And lots, lots more!
