"TestRunner" "PlayMode" test leaves behind "InitTestScene..." scene assets after test runs

Unity Test Runner


Reproduction steps:

1. Create a New Project
2. "Window" -> "Test Runner"
3. "PlayMode"
4. "Enable Playmode tests"
5. Restart Editor
6. "Create Playmode tests with methods"
7. Spam "Run All"

Fixed in: 2018.1.0a7

Expected Result: Spamming isn't allowed and only one test at a time is run, with only one temporary scene created for that one test
Actual Result: Only one test is run, but multiple scenes are created, leaving all untested scenes in the assets folder

Reproduced with: 2017.8.0a1, 2017.3.0b4, 2017.2.0f3, 2017.1.2p1, 5.6.4f1, 5.6.0f3
Did not reproduce on: 5.5.5f1(Play Mode tests were only implemented in 5.6)

Reproduced on both Windows 10 and mac 10.12.6

    This is still present in 2019.4.16. I also see an error message in the console: NullReferenceException: Object reference not set to an instance of an object
    UnityEditor.TestTools.TestRunner.PlaymodeLauncher+BackgroundWatcher.OnPlayModeStateChanged. Framework version 1.1.19

    Still happening, very easy to repro:
    Create a playmode unit test that OPENS an existing scene (addictively) and when the test finish the InitTestScene is left behind.

    This happens to me in 2020.1f1 as well. I'm using the SceneManager to open existing scenes to test those with runtime tests, but now I have a bunch of these "InitTestScene" files under the assets folder.

    Seeing this in Unity 2019.3.3f1 - how is this "resolved"?
