  • Clean - Low redundancy in output. Result statistics for each test is vertically aligned.

  • Colorful - Terminal output makes good use of color when the terminal supports it.

  • Fast - Tests run in independent processes. (One per processor by default. Does not play nicely with gevent.)

  • Powerful - Multi-target + auto-discovery.

  • Traditional - Use the normal unittest classes and methods for your unit tests.

  • Descriptive - Multiple verbosity levels, from just dots to full docstring output.

  • Convenient - Bash-completion and ZSH-completion of options and test targets.

  • Thorough - Built-in integration with coverage

  • Modern - Supports Python 3.5+. Additionally, PyPy is supported on a best-effort basis.

  • Portable - macOS, Linux, and BSDs are fully supported. Windows is supported on a best-effort basis.

  • Living - This project grows and changes. See the changelog
