Which of the following is the correct syntax to parameterize a test function with two parameters username and password using pytest?

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

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

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

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

Step-by-Step Solution

Solution:

Step 1: Recall pytest parameterize syntax
The correct syntax uses @pytest.mark.parametrize with a string of comma-separated parameter names and a list of tuples for values.
Step 2: Compare options
@pytest.mark.parametrize('username, password', [('user1', 'pass1'), ('user2', 'pass2')]) matches the correct syntax exactly. Others have wrong decorator names or wrong argument formats.
Final Answer:
@pytest.mark.parametrize('username, password', [('user1', 'pass1'), ('user2', 'pass2')]) -> Option D
Quick Check:
Correct decorator and tuple list = @pytest.mark.parametrize('username, password', [('user1', 'pass1'), ('user2', 'pass2')]) [OK]

Quick Trick: Remember: mark.parametrize with string params and list of tuples [OK]
