Abstract

xunitgen is a python module for the simple production of xunit or junit XML files for use in continuous integration. Such as with Jenkins.

It converts a stream of timed (start/finish/error) events and convert them into a report.

It brings / need no dependencies besides an installation of Python 2 or Python 3.

Using

Once you have added the directory surrounding xunitgen into your PYTHONPATH, you can create simple test steps by using the xunitgen.Recorder:

import xunitgen

destination = xunitgen.XunitDestination('.')

with xunitgen.Recorder(destination, 'my-test-suite') as recorder:
    with recorder.step('a-success') as step:
        pass

    with recorder.step('a-failing-test') as step:
        step.error('this step has failed')

    with recorder.step('another-failing-test'):
        raise Exception('I have failed too!')

Which will produce a file named my-test-suite.xml under the current directory

Lower level, event API

You can also use a lower level API (EventReceiver) if you need finer control:

import xunitgen

receiver = xunitgen.EventReceiver()
receiver.begin_case('a-test', 0, 'foo')
receiver.failure('because', 'ExceptionFoo')
receiver.end_case('a-test', 9)

print xunitgen.tostring(receiver.results())

Example (event_trace module)

The xunitgen.event_trace module shows an example of using the lower level API to convert a tracing format to xUnit files. This can be used for instance by C programs/tests to produce test traces without having to implement the xUnit format.

Contributing

If you want to make code contributions to xunitgen here are the steps to follow to get a working development environment:

Create a virtual environment and activate it

$ virtualenv venv
$ . venv/bin/activate

Install development dependencies

$ pip install -r dev_requirements.txt

With the virtual environment active, test your changes before submitting:

$ nosetests -s tests
