haas: Extensible Python Test Runner

haas is a Python test runner that is backward-compatible with Python's built-in unittest Test Cases, but supports more advanced features, such as project-specific plugins.

Features

• Runs unittest.TestCase based tests!
• Plugin system, based on stevedore.
  • Still subject to change and revision to clean the plugin APIs.
  • Plugins for whole-test-run environment configuration (run before any client-code is imported).
  • Plugins for test result output formatting.
  • Plugins for test runner scheme (e.g. parallel runner)
• Generic test result collection, presentation & output handled by plugins.
• (Very) Basic parallel test run support.

Missing (unittest) Features

• Does not support the unittest.load_tests protocol.
• Does not support subtests.

Future Features

• Per-project config file
• Improve parallel test runner to allow conditional splitting of tests, or allow tests to be run in the main process.
• Improve plugin system
• More result output plugins/options (xunit, result summary)
• ... ?
