micropytest 0.3.1

A micro test runner

microPyTest

microPyTest is a minimal, pure python-based test runner that you can use directly in code.

Key Points

• Code-first approach: Import and run tests from your own scripts.
• Artifact tracking: Each test can record artifacts (files or data) via a built-in test context.
• Lightweight: Just Python. No special config or advanced fixtures.
• Optional CLI: You can also run tests via the micropytest command, but embedding in your own code is the primary focus.

Installation

pip install micropytest

Usage in Code

Suppose you have some test files under my_tests/:

# my_tests/test_example.py
def test_basic():
    assert 1 + 1 == 2

def test_with_context(ctx):
    ctx.debug("Starting test_with_context")
    assert 2 + 2 == 4
    ctx.add_artifact("numbers", {"lhs": 2, "rhs": 2})

You can run them from a Python script:

import micropytest.core

results = micropytest.core.run_tests(tests_path="my_tests")
passed = sum(r["status"] == "pass" for r in results)
total = len(results)
print("Test run complete: {}/{} passed".format(passed, total))

• Each test that accepts a ctx parameter gets a TestContext object with .debug(), .warn(), .add_artifact(), etc.
• Results include logs, artifacts, pass/fail/skip status, and duration.

Differences from pyTest

If you’re coming from pytest:

1. No fixtures or plugins

   microPyTest is intentionally minimal. Tests can still share state by passing a custom context class if needed.

2. No complex configuration

   There’s no pytest.ini or conftest.py. Just put your test functions in test_*.py or *_test.py.

3. Artifact handling is built-in

   ctx.add_artifact("some_key", value) can store files or data for later review. No extra plugin required.

4. Time estimates for each test

5. Code-first

   You typically call run_tests(...) from Python scripts. The CLI is optional if you prefer it.

Quickstart

See the examples subfolder

Optional CLI

If you prefer a command-line flow:

micropytest [OPTIONS] [PATH]

• -v, --verbose: Show all debug logs & artifacts.
• -q, --quiet: Only prints a final summary.

Example:

micropytest -v my_tests

Changelog

Enjoy your micro yet mighty test runner!
