I'm using the community edition (2016.3.2 64 bit). After I ran a test, I clicked the "Toggle auto-test" button in the debugger: https://www.jetbrains.com/help/img/idea/2016.3/icon_toggleAutoTest.png
However, that doesn't seem to have any effect. I have changed the tests, I have changed the class under test, I have force-saved my files using Ctrl+S - the tests aren't rerun. What am I doing wrong?
