Sample questions

Excerpts from this guide's answers.

Q6. What does expect provide compared with a plain assert?

expect(locator).to_have_text(...) and similar assertions retry until the condition is met or the timeout (5 seconds by default) expires.

Q21. Which locators does Playwright recommend in Python?

Prefer user-facing locators: get_by_role with a name, get_by_label, get_by_placeholder, get_by_text, get_by_alt_text and get_by_title.

Q81. What are pytest fixtures?

Fixtures are functions decorated with @pytest.fixture that provide test dependencies; tests request them by parameter name.
