xUnit.net Analyzers 1.3.0 Pre-Release (build 13)

This is co-released with core framework release v2 2.5.1-pre.20.

Usage Analyzers

• We have added a fixer for xUnit1029 which removes the [Fact] or [Theory] attribute from the local function.
• We have introduced a new analyzer (xUnit1030) that will flag usage of ConfigureAwait on tasks as being problematic. Calling this on a task inside a test method will cause the remainder of the test method to be run on a thread pool thread rather than the original thread (which is used to limit the number of tests that run concurrently in parallel). xunit/xunit#2628
• We have introduced a new analyzer (xUnit1031) that will flag usage of blocking task operations in a test method as being problematic. The operations that are flagged include:
  • Task.GetAwaiter().GetResult()
  • Task.Wait()
  • Task.WaitAll()
  • Task.WaitAny()
  • Task.GetAwaiter().GetResult()
  • Task.Result
  • ValueTask.GetAwaiter().GetResult()
  • ValueTask.GetAwaiter.GetResult()
  • ValueTask.Result
  Calling these inside a test method could cause performance issues and/or cause the test to become deadlocked, due to the limited number of threads available for running tests in parallel. xunit/xunit#1390
