Testing async code

Async test support is built in. No plugins or extra configuration required.

Writing async tests

Use @test with async def:

from tryke import expect, test

@test
async def fetches_data():
    result = await some_coroutine()
    expect(result).to_equal(42)

That's it. tryke detects async test functions and runs them on an event loop automatically.

Comparison with pytest

pytest requires pytest-asyncio and a marker:

import pytest

@pytest.mark.asyncio
async def test_fetches_data():
    result = await some_coroutine()
    assert result == 42

tryke needs neither — @test + async def is all you need.

All decorators work with async

skip, todo, xfail, and skip_if all work the same on async tests:

@test.skip("service unavailable in CI")
async def calls_external_api():
    ...

@test.xfail("race condition under investigation")
async def concurrent_writes():
    ...
