PyTest :: Python Testing framework for unit testing, system testing , integration testing everything ....

PyTest Rough Points:

1.capsys -> The capsys builtin fixture provides two bits of functionality: it allows you to retrieve stdout and stderr from some code, and it disables output capture temporarily. Let’s take a look at retrieving stdout and stderr.

2. Marker -> can be specified in the pytest.ini  to mark the test.

3. Incremental -> if it fails we can asks remaining all to fail by calling pytest.mark.incremental decorator

4. Python Fixtures -> Autouse , scope=[function, module, session etc] for dependency injection.

5. Python Fixtures can take parameters as well.

6. Pytest to parallelise the test cases using pytest-xdist  like due to multiple platforms , multiple nodes etc

7. Fixtures in Fixtures can be used like DB table existence checking can use another fixture for DB connection.

8. Within the fixture we can skip/fail TCs if that Fixture function has abnormal o/p behaviour.

9. Assert -> Pytest test case validation.

10. Conftest.py -> for the Command Line Arguments  to pytests using pytest_addoption hooks.
