Which of the following shows the correct way to use pytest's parametrize decorator for multiple parameters in Selenium tests?

A@pytest.parametrize('username password', [('user1', 'pass1'), ('user2', 'pass2')])

B@pytest.mark.parametrize('username, password', [('user1', 'pass1'), ('user2', 'pass2')])

C@pytest.mark.parametrize(['username', 'password'], ['user1', 'pass1'])

D@pytest.parametrize('username, password', 'user1', 'pass1')

Step-by-Step Solution

Solution:

Step 1: Syntax of parametrize
pytest.mark.parametrize takes a string of comma-separated parameter names and a list of tuples with values.
Step 2: Verify options
@pytest.mark.parametrize('username, password', [('user1', 'pass1'), ('user2', 'pass2')]) correctly uses the decorator with parameter names and a list of tuples.
Final Answer:
@pytest.mark.parametrize('username, password', [('user1', 'pass1'), ('user2', 'pass2')]) -> Option B
Quick Check:
Parametrize needs parameter names string and list of tuples [OK]
