title: Error when running Python parameterized test method
body: <p><strong>IDE:</strong> PyCharm Community Edition 3.1.1<br>
  <strong>Python:</strong> 2.7.6  </p>
  
  <p>I using <strong>DDT</strong> for test parameterization <a href="http://ddt.readthedocs.org/en/latest/example.html" rel="noreferrer">http://ddt.readthedocs.org/en/latest/example.html</a></p>
  
  <p>I want to choose and run parameterized test method from test class in <strong>PyCharm</strong> -> see example:</p>
  
  <pre><code>from unittest import TestCase
  from ddt import ddt, data
  
  
  @ddt
  class Test_parameterized(TestCase):
      def test_print_value(self):
          print 10
          self.assertIsNotNone(10)
  
      @data(10, 20, 30, 40)
      def test_print_value_parametrized(self, value):
          print value
          self.assertIsNotNone(value)
  </code></pre>
  
  <p>When I navigate to the first test method <code>test_print_value</code> in code and hit <kbd>ctrl</kbd>+<kbd>Shift</kbd>+<kbd>F10</kbd> (or use <code>Run Unittest test_print...</code> option from context menu)
  then test is executed.</p>
  
  <p>When I try the same with parameterized test I get error:</p>
  
  <pre><code>Test framework quit unexpectedly
  </code></pre>
  
  <p>And output contains:</p>
  
  <pre><code>/usr/bin/python2 /home/s/App/pycharm-community-3.1.1/helpers/pycharm/utrunner.py
  /home/s/Documents/Py/first/fib/test_parametrized.py::Test_parameterized::test_print_value_parametrized true
  
  Testing started at 10:35 AM ...
  
  Traceback (most recent call last):
    File "/home/s/App/pycharm-community-3.1.1/helpers/pycharm/utrunner.py", line 148, in &lt;module&gt;
      testLoader.makeTest(getattr(testCaseClass, a[2]), testCaseClass))
  AttributeError: 'TestLoader' object has no attribute 'makeTest'
  
  Process finished with exit code 1
  </code></pre>
  
  <p>However when I run all tests in class (by navigating to test class name in code and using mentioned run test option) all parameterized and non parameterized tests are executed together without errors.</p>
  
  <p>The problem is how to independently run prameterized method from the test class - workaround is putting one parameterized test per test class but it is rather messy solution.</p>
