title: What does "'tests' module incorrectly imported" mean?
body: <p>I have copied a working test line by line and just changed a few names (at least so I thought) and now I get this very cryptic error: (I have replaced some stuff with FOO, BAR)</p>
  
  <pre><code>ImportError: 'tests' module incorrectly imported from 'FOO/exports/tests'. Expected 'FOO/exports'. Is this module globally installed?
  </code></pre>
  
  <p>The problem is that I do not understand the error at all. What does this error message mean?</p>
  
  <p>Complete stacktrace:</p>
