Testing

• Read existing tests inside /tests/ folder to get an idea of how the tests are organized.
• Get yourself familiar with fixtures & factories. They are your friend.
• Read https://splinter.readthedocs.org/en/latest/api/driver-and-element-api.html to get your self with all the methods available with browser fixture. You must include base_url fixture, in your test cases to start a Live Test Server.

Run tests partially

py.test tests/unit # Will only the tests inside tests/unit folder
py.test tests/unit/tests/app_model.py # Will only test inside app_model.py

This approach will reduce your testing time, while you are writing a new feature or fixing a bug. Once your sure, the test in a particular section is passing you can run all the test with py.test.

Run test with html coverage report

py.test --cov-report=html --cov

Open htmlcov/index.html in your browser to see all the lines that are not getting covered during testing. Try to increase the overall percentage of test coverage in the project.

Faster browser test with headless browser

py.test --splinter-webdriver=phantomjs

Functional test with selenium using Firefox can be quiet time consuming. You can install phantomjs and use --splinter-webdriver=phantomjs parameter with py.test. Checkout all the parameters available at https://github.com/pytest-dev/pytest-splinter#command-line-options

Use pdb while testing

py.test --pdb

Whenever a test fails, it will drop you into into a interactive python debugger where you can inspect the local variable and step into codebase.

Always obey the testing goat!
