Retrieved 2026-11-10Async OneTimeSetup/OneTimeTearDown are now supported, fixing an issue where tests using it would hang or crash the editor.
Fixed an issue where assembly-level ITestAction attributes with ActionTargets.Test were not invoked for individual test methods, and ITest.Fixture was null when accessed from ITestAction callbacks.
Profiler marker recorders used by Measure.Method now start when the measured iterations begin instead of when ProfilerMarkers() is called, so warmup and probing iterations no longer contribute to the reported marker values or add sample collection overhead to those phases.
Measure.Method().GC() again forces a full garbage collection immediately before each timed region, restoring the behavior from before the switch to the ProfilerRecorder API. Without it, a collection triggered by the measured code's own allocations lands inside the timed region and shows up as periodic spikes across the samples. As before: this only happens when GC() is specified; warmup and probing iterations are not affected; and because SetUp/CleanUp cause each of the IterationsPerMeasurement inner executions to be timed separately, that combination gets one collection per inner execution rather than one per sample, which makes it considerably slower. Reported times for allocating methods measured with GC() will change, generally becoming lower and more stable, so baselines recorded since 3.2.1 are not comparable.
