Issue ID




Test runs indefinitely and Editor crashes after running the test that reads/writes code that contains interfaces

Package: Test-Framework


How to reproduce:
1. Open the attached project "" and open Test Runner window
2. In the Test Runner window click Run All (at least 3 times, more information in the notes)
3. Observe the Unity Editor

Expected result: The test would fail due to a null exception, just like when running the test for the first time
Actual result: The test repeats indefinitely, Unity Editor becomes unusable, cannot cancel the Test Runner, forcing the Unity Editor to close leads to crash

Reproducible with: Test Framework 1.1.0 (2019.2.0a10, 2019.2.20f1), Test Framework 1.1.9 (2019.2.20f1, 2019.3.0f6), Test Framework 1.1.11 (2019.2.20f1,2019.3.0f6, 2020.1.0a22)
Could not test with: 2017.4.36f1, 2018.4.16f1, Test Framework 1.0.18 (2019.2.0a10, 2019.2.20f1) (the Script doesn't compile, due to differences of access modifiers of certain functions and missing references)

-The issue behavior is unstable, sometimes it requires running the test only once to reproduce
-Not always the Crash Bug Reporter window pops up when Unity Editor crashes after forcing it to close
-Crashes without stacktrace on 2019.3
-Not reproducible on Mac
