Test Runner's results change after first Test run when using Singleton

Unity Test Runner

-

To reproduce:
1. Open attached project ("SingletonInstancesTest")
2. In Test Runner window click "Run All"
- Tests return positive
3. Run Tests again
- Tests return negative

Expected: Results are the same after every run
Actual: Results change to negative after first run

Reproduced with: 2017.4.20f2, 2018.3.6f1, 2019.1.0b4, 2019.2.0a6

Note:
- Issue occurs only when tests are run EditMode

    Resolution Note:

    The test is working as intended.
    The singleton is being reinitialized whenever it is not present in its static variable, which will only happen after a domain reload. When running an editmode test, no domain reload will happen, unless needed. Thus the singleton from the previous run still exists.

    A recommend solution could be to do a TearDown in the test, which destroys the singleton, as cleanup.
