title: Removing tests from unittest suite
body: <p>In order to run all my unittests I use following script where test_files is a list of strings of my testfiles:</p>
  
  <pre><code>for test_file in test_files:
      test_file = test_file[:-3]
      module = __import__(test_file)
      for name, obj in inspect.getmembers(module):
          if inspect.isclass(obj):
              if str(obj).startswith("&lt;class 'test_"):
                  suite.addTest(unittest.TestLoader().loadTestsFromTestCase(obj))
  </code></pre>
  
  <p>How can I remove single tests from the suite afterwards (not all tests from a testfile)?</p>
