A easy to use replacement to unittest to output it's results in XML format.

[Otavio Salvador <otavio@…>]

Current Bitten code has its own unittest code to export the unittests results to XML. Would be good if we have a replacement, mostly like trace.py python module, to be able to use and grab it's results without the need of code it specifically to integrate with bitten.

Actually, the unittest distutils command (from bitten.util.testrunner​) is not specific to Bitten. It is, however, specific to distutils, and cannot be easily used standalone. This should be fixable, though.

Also, it'd be nice if <python:unittest> was able to parse the standard verbose output of unittest. That will take some trickery to extrapolate the file names from the names of the test cases, but it should be possible to capture most of the info currently captured by the XML test results.

In [230] I added a command-line interface to the bitten.util.testrunner​ so that it can now be used in a standalone fashion.

I tried to use it and it fail.

Bellow you can see the log:

[cmlenz]

That error is due to the script bitten/util/testrunner.py being packaged in an egg. Thus the script does not map to an actual file on the file system, and cannot be run this way.

As a workaround, I've added a function attribute to the <python:exec> command in [253].

Now you can use the following declaration:

<python:exec module="bitten.util.testrunner" function="main"
    output="build/test-results.xml"
    args="--xml-results build/test-results.xml
          --coverage-summary build/coverage.txt
          --coverage-dir build/coverage
          tests.tests" />
