Tryke

Highlights

Fast Rust-powered test discovery
Concurrent tests by default
Pretty, per-assertion diagnostics
Soft assertions (like pytest-check)
Native async support — no plugin
Watch mode
Changed mode (like pytest-picked)
Client/server mode for fast editor integrations
Fixtures with setup / teardown and typed Depends() injection
Parametrized tests via @test.cases
Grouping with describe() blocks
skip, skip_if, xfail, and todo markers
In-source testing
Support for doctests
Filtering and marks
Reporters — text, dot, json, junit, llm, nextest-style, and pytest-sugar-style

Getting started

Run tryke with uvx to get started quickly:

uvx tryke

Or, check out the tryke playground to try it out in your browser.

To learn more about using tryke, see the documentation.

from typing import Annotated

from tryke import Depends, describe, expect, fixture, test


@fixture(per="scope")
def database():
    db = {}
    yield db
    db.clear()


with describe("users"):

    @fixture
    def users(database: Annotated[dict[str, dict[str, str]], Depends(database)]):
        database["users"] = {}

        return database["users"]

    with describe("get"):

        @test("returns a stored user")
        async def test_get(users: Annotated[dict[str, str], Depends(users)]):
            users["alice"] = "alice@example.com"

            expect(users["alice"], name="returns stored email").to_equal(
                "alice@example.com"
            )

    with describe("set"):

        @test("stores a new user")
        async def test_set(users: Annotated[dict[str, str], Depends(users)]):
            users["bob"] = "bob@example.com"

            expect(users["bob"], name="stores email under user key").to_equal(
                "bob@example.com"
            )

Run the tests:

uvx tryke test # run once
uvx tryke # watch mode
