title: VS Code does not recognize unit tests in Flutter
body: <p>Visual Studio Code does not recognize unit tests grouped in <code>group(...)</code>. But it recognizes unit tests which are not grouped. I mean they are standalone <code>test(...)</code>. I want to use group, because I need <code>setUp()</code>.</p>
  
  <p>There is <code>Run | Debug</code> link above <code>group</code>. When I click Debug or Run the Debug console shows <code>No tests match regular expression "^LocalRepository$".</code></p>
  
  <p>The tests are running correctly with <code>flutter test</code> command.</p>
  
  <p>Dart SDK: >=2.1.0 &lt;3.0.0</p>
  
  <p>Flutter channel: master</p>
  
  <p>Edit: I found workaround - I just don't use <code>group</code> callback. But I can't run all tests by clicking <code>Run</code> above <code>group</code>.</p>
