4.11.0
NUnit Analyzers 4.11 - October 28, 2025
This release of the NUnit Analyzers includes improvements and fixes related to IDisposable handling and initialization
in SetUp and OneTimeSetUp methods. It also introduces the ability to configure additional methods that should be
treated as SetUp and TearDown methods by the analyzers. This can be done in the .editorconfig, and there are four
configurations for this:
dotnet_diagnostic.NUnit.additional_setup_methodsdotnet_diagnostic.NUnit.additional_teardown_methodsdotnet_diagnostic.NUnit.additional_one_time_setup_methodsdotnet_diagnostic.NUnit.additional_one_time_teardown_methods
Each configuration accepts a list of method names, separated by commas, semicolons, or spaces. For example:
dotnet_diagnostic.NUnit.additional_setup_methods = CustomSetup, MyInit
As in recent releases, a major part of this work was contributed by @manfred-brands.
