Internal Program Version: python-subunit  1.4.0

Subunit is a streaming protocol for test results.  The protocol is a
binary encoding that is generated and parsed.  By design, all the
components of the protocol conceptually fit into the xUnit TestCase -
TestResult interaction.

Subunit comes with command line filters to process a subunit stream and
language bindings for Python, C, C++ and Shell. Bindings can be
written for other languages.

A number of useful things can be done easily with subunit:
- Test aggregation: Tests run separately can be combined and then
  reported/displayed together.  For instance, tests from different
  languages can be shown as a seamless whole.
- Test archiving: A test run may be recorded and replayed later.
- Test isolation: Tests that may crash or otherwise interact badly with
  each other can be run separately and then aggregated, rather than
  interfering with each other.
- Grid testing: subunit can act as the necessary serialization and
  deserialization to get test runs on distributed machines to be
  reported in real time.
