test 0.1.1 on Edge Python

test

test is a unit-test harness written in Edge Python. Tests register with decorators, fixtures are injected by keyword, and run() reports each test and exits with a code a runner can read.

from test import fixture, test, raises, run

@fixture
def user():
    return {"name": "Ana"}

@test("user has a name", "user")
def has_a_name(user):
    assert user["name"] == "Ana"

@test("division by zero raises")
def divides():
    with raises(ZeroDivisionError):
        1 / 0

run()

{
  "imports": {
    "test": "0.1.1"
  }
}

pass. user has a name
pass. division by zero raises
2 passed, 0 failed

Output

@fixture registers a factory under its function’s name. Every test that names it gets a fresh one, so no test leaks state into another. @test(description, *uses) registers a test and the fixtures it takes.

raises(exc_type, match=None) asserts that the block raises exc_type, a class or a tuple of classes. With match the message must also contain that text, so the right exception raised for the wrong reason still fails.

from test import test, raises, run

def check(n):
    if n < 0:
        raise ValueError("must be positive")
    return n

@test("rejects negatives")
def rejects():
    with raises(ValueError, match="must be positive"):
        check(-1)

run()

{
  "imports": {
    "test": "0.1.1"
  }
}

pass. rejects negatives
1 passed, 0 failed

Output

run() prints a pass., fail. or error. line per test and a summary, then raises SystemExit(1) if anything failed and SystemExit(0) otherwise. A failed assertion carries its message. edge test drives what a file registered, so a test file needs no run() of its own.

from test import test, run

@test("two plus two")
def adds():
    assert 2 + 2 == 4

@test("this one fails")
def fails():
    assert "a" in "zzz", "letter missing"

run()

{
  "imports": {
    "test": "0.1.1"
  }
}

pass. two plus two
fail. this one fails (AssertionError: letter missing)
1 passed, 1 failed

Output

edge test finds every *_test.py file and reads each verdict from that exit code.
