title: Prevent IntelliJ from compiling src-Classes when Unit-Testing
body: <p>I have the following Project Structure</p>
  
  <pre><code>/
     src/  # src-files for the app
      org.mayapp.main.Main/
   test/ # unit-tests
      org.myapp.test.main.MainTestSuite/
  </code></pre>
  
  <p>When I want to run my Unit-Tests, e.g. <code>org.myapp.test.main.MainTestSuite</code>, IntelliJ always tries to compile <strong>all</strong> the packages in the whole project.</p>
  
  <p>I want to prevent this, because I am currently developing on a part of my app and still want to run the Unit-Tests on other parts of the app.</p>
  
  <p>Is there a way to prevent IntelliJ from compiling the whole project before running the Unit-Tests?</p>
