title: How do I specify a single test in a file with nosetests?
body: <p>I have a file called test_web.py containing a class TestWeb and many methods named like  test_something().</p>
  
  <p>I can run every test in the class like so:</p>
  
  <pre><code>$ nosetests test_web.py 
  ...
  ======================================================================
  FAIL: checkout test
  ----------------------------------------------------------------------
  Traceback (most recent call last):
    File "/Users/me/path/here/test_web.py", line 187, in test_checkout
  ...
  </code></pre>
  
  <p>But I can’t seem to run individual tests. These give me “No such test” errors when run in the same PWD:</p>
  
  <pre><code>$ nosetests test_web.py:test_checkout
  $ nosetests TestWeb:test_checkout
  </code></pre>
  
  <p>What could be wrong here?</p>
