pytest-trio: Pytest plugin for trio¶
This is a pytest plugin to help you test projects that use Trio, a friendly library for concurrency and async I/O in Python. Features include:
- Async tests without the boilerplate: just write
async def test_whatever(): ....
- Useful fixtures included: use
autojump_clockfor easy testing of code with timeouts, or
nurseryto easily set up background tasks.
- Write your own async fixtures: set up an async database connection or start a server inside a fixture, and then use it in your tests.
- If you have multiple async fixtures, pytest-trio will even do setup/teardown concurrently whenever possible. (Though honestly, we’re not sure whether this is a good idea or not and might remove it in the future. If it makes your tests harder to debug, or conversely provides you with big speedups, please let us know.)
- Integration with the fabulous Hypothesis library, so your async tests can use
property-based testing: just use
@givenlike you’re used to.
- Support for testing projects that use Trio exclusively and want to use pytest-trio everywhere, and also for testing projects that support multiple async libraries and only want to enable pytest-trio’s features for a subset of their test suite.
