Pytest and coverage Toolpy.test <files>
| Run py.test tool | --maxfail=X
| Exit after failing X tests | --durations=10
| Use this to Profile your tests (time taken) | --cov=path
| Run coverage within the project path | --cov-report term-missing
| Add this to show which lines were not covered |
Packages to install:
pip install pytest
pip install pytest-sugar
pip install pytest-cov Pytest with Flaskclient = app.test_client()
| Gives you an Test Client object | client.get(url)
| Makes a GET request | client.post(url, data=[])
| Makes a POST request | client.put(url, data=[])
| Makes a PUT request |
You can create a test client to test your Flask app Coverage Configuration File.coveragerc
| Default filename looked for | [report]
| Section defining the report | exclude_lines =
| Exclude lines defined after | |
Write after exclude_lines = the lines as they are in Python code | | Fixture@pytest.fixture()
| Fixture decorator | scope="session"
| Scope for the fixture: Can be session, module, class or function | params=[]
| For each value, the fixture will be called with that value (this makes multiple calls) | autouse=False
| All tests in the session use the fixture automatically | def my_fixture(request)
| Putting request object in fixture gives you access to the pytest request (e.g. put a finalizer) | pytest --fixtures
| See all available fixtures |
The purpose of test fixtures is to provide a fixed baseline upon which tests can reliably and repeatedly execute. pytest-mockIn short, mocking is creating objects that simulate the behaviour of real objects. |
