What is the scope of fixtures in pytest?

In pytest, the scope of a fixture defines how long the fixture will last. It can be set to function, class, module, or session.

Can you explain the different scopes available?

Sure! The scopes are: 'function' (default), which runs the fixture for each test; 'class', which runs it once per class; 'module', which runs it once per module; and 'session', which runs it once per test session.

When should I use session scope?

Use session scope for expensive setup that you want to share across multiple tests, like database connections.

What happens if I use a fixture with a broader scope than needed?

Using a broader scope can lead to shared state between tests, which might cause tests to interfere with each other, leading to flaky tests.
