"""
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.
import unittest
import BSTestRunner
... define your tests ...
if __name__ == '__main__':
BSTestRunner.main()
For more customization options, instantiates a BSTestRunner object.
BSTestRunner is a counterpart to unittest's TextTestRunner. E.g.
# output to a file
fp = file('my_report.html', 'wb')
runner = BSTestRunner.BSTestRunner(
stream=fp,
title='My unit test',
description='This demonstrates the report output by BSTestRunner.'
)
# Use an external stylesheet.
# See the Template_mixin class for more customizable options
runner.STYLESHEET_TMPL = ''
# run the test
runner.run(my_test_suite)
