Transcript

1. webtest & pytest a quick look at Python Ireland Meetup - December 2014 Jakub Jarosz @qba73
2. webtest • test webapp without HTTP srv • full stack functional / integration testing • does not replace unit tests!
3. webtest - testing wsgi app Our app ready for testing (no http srv)
4. webtest - testing non wsgi app
5. webtest - testing non wsgi app
6. pytest - basic
7. pytest - basic verbose mode (test names)
8. pytest - fixture decorator
9. pytest - fixture decorator / caching
10. pytest - fixture scope • session • package • module • class • function Global fixtures Module fixtures
11. pytest - fixture scope module fixture module fixture
12. pytest - interdependent fixtures / scope apiapp - global fixture, session level module level fixture
13. pytest - xfail global fixture, session level
14. pytest - using markers global fixture mark tests that do not change user data
15. pytest - using markers global fixture pytest marker py.test tests/ -v -m “e2e” py.test tests/ -v -m “not e2e”
16. pytest - parametrized fixtures the same param! global fixture, session scope
17. pytest - parametrized fixtures • pytest automatically generates tests with given parameters. • It is a perfect solution for data driven tests with the same business logic.
18. pytest - parametrized fixtures
19. pytest - finalizers aka tearDown()
20. pytest - hooks project - myapp - tests - conftest.py - test_module1.py - test_module2.py • pytest_sessionstart() • pytest_sessionfinish() • pytest_runtestsetup() • pytest_runtest_teardown() • pytest_addoption()
21. pytest - plugins http://pytest-plugs.herokuapp.com/
