Follow at your own risk!

Tips for using the Selenium WebDriver

1. Make sure to use driver methods to see where you're at! eg: driver.page_source tells you what page you're on!
2. Make sure test cases are proper - you can check if an element exists; and more!

Using the pytest command on the CLI

In this section you'll find different ways you can use the pytest command on CLI; most notably i found these to be helpful. (http://doc.pytest.org/en/latest/usage.html)
pytest -v --cov - this throws verbose and coverage
pytest -v --cov=<projectname> this throws verbose and coverage for specific project

Otherwise, you can also set up configuration files - so you don't have to type in pytest with long flags each time.

Configurating Pytest for Django

PS: Not required for CA.
You'll need the two plugins for pytest

1. pytest-django
2. coverage.py plugin (is installed by default - I believe!)

Step 1. Create two files in the root of your project directory (./pytest.ini & ./.coveragerc)
Step 2. Configure the two files in the following manner:
pytest.ini (http://doc.pytest.org/en/latest/customize.html)

[pytest]
python_files = tests.py test_*.py *_tests.py
DJANGO_SETTINGS_MODULE = personal_portfolio.settings
addopts = --cov=. --cov-report html --cov-config=.coveragerc 

.coveragerc (https://coverage.readthedocs.io/en/latest/config.html)

[run]
omit = */manage.py, */wsgi.py, */urls.py, */views.py, */forms.py
branch = true
source = .

[report]
show_missing = false

Most importantly, check that the two files are coupled with the --cov-config=.coveragerc flag.
Step 3. You can run pytest with just the pytest -v now and it should run it with all the addopts.
