title: Intellij does not run tests
body: <p>After importing my project into Intellij and getting it to build successfully, I am trying to run some of my project's tests. I navigate to the test file and select Run -> Run. However, this does not run my tests, just opens a small "Edit Configurations" window, as the attached photo shows.</p>

  <p>And, when I select Edit Configurations as prompted, JUnit is not to be found. The window is shown below.</p>

  <p>What do I need to do to run the tests?</p>
