Source code for pySPACE.tests.HTMLTestRunner

"""
A TestRunner for use with the Python unit testing framework. It
generates a HTML report to show the result at a glance.

The simplest way to use this is to invoke its main method. E.g.

    .. code-block:: python

        import unittest
        import HTMLTestRunner

        # ... define your tests ...

        if __name__ == '__main__':
            HTMLTestRunner.main()

# The redirectors below are used to capture output during testing. Output
# sent to sys.stdout and sys.stderr are automatically captured. However
# in some cases sys.stdout is already cached before HTMLTestRunner is
# invoked (e.g. calling logging.basicConfig). In order to capture those
# output, use the redirectors for the cached stream.
#
# e.g.
#   >>> logging.basicConfig(stream=HTMLTestRunner.stdout_redirector)
