     inc_slow : bool
       Include slow tests, like IPython.parallel. By default, these tests aren't

     slimerjs : bool
       Use slimerjs if it's installed instead of phantomjs for casperjs tests.
 
     url : unicode

     xunit : bool
       Produce Xunit XML output. This is written to multiple foo.xunit.xml files.
 
     coverage : bool or str
       Measure code coverage from tests. True will store the raw coverage data,
       or pass 'html' or 'xml' to get reports.
