Junit5 and Instrumentation Tests running when running unit tests

Question

I upgraded my tests to junit5 now when I run my unit tests it also runs my instrumentation test which of course causes errors as they're not running in a simulator. How do I stop it from running them? I was able to solve some of the errors using @RunWith(AndroidJUnit4::class) but I still have one error and it's driving me crazy

this is the error, however, I do not understand why my instrumentation tests are now running when I click on Run???

multiple options first individually for tests:

• @Ignore if you want to completely disable

• put assumeTrue(condition); to deactivate a test on runtime conditions

• and then you can also do this: start the test first then click on the dropdown menu at the top that displays your run configuration click on Edit Configurations

  • change the folder of the configuration to one that excludes your specific tests
  • or switch test kind to pattern and hope you have some kind of naming convention for the excluding testfiles then you can write a regex pattern that only includes the ones you want
