Account creds must be defined in the data/existing_user.json file. To run tests system must have corresponding webdriver for browser: Chrome - chromedriver, Firefox - geckodriver, etc.

For example:

Run test module via default browser Chrome:

$ pytest tests/test_blog.py

Run specific class or single test method:

$ pytest tests/test_blog.py::TestBlog or

$ pytest tests/test_blog.py::TestBlog::test_post_blog

Run test module via specific browser:

$ pytest --browser=firefox tests/test_blog.py

Code convention:

Use PEP-8, but with:

1. 100 symbols hard wrap.
2. Full typing. If something imported in file just for typing - we must put it in "if TYPE_CHECKING:" construction.
3. All data transfers must be done through dto object and fixture for it.
4. Every test groups in blocks GIVEN/WHEN/THEN.
