PyTest - Basics and Setup

You want to test a function multiply(a, b) that returns the product of two numbers. Which PyTest test function correctly tests that multiply(3, 4) returns 12?

Adef test_multiply():\n assert multiply(3, 4) == 7

Bdef test_multiply():\n assert multiply(3, 4) = 12

Cdef multiply_test():\n assert multiply(3, 4) == 12

Ddef test_multiply():\n assert multiply(3, 4) == 12

Step-by-Step Solution

Solution:

Step 1: Verify test function name
The function name must start with test_, so test_multiply is correct.
Step 2: Check assertion correctness
The assertion must compare with == and the expected result is 12, so assert multiply(3, 4) == 12 is correct.
Final Answer:
def test_multiply():\n assert multiply(3, 4) == 12 -> Option D
Quick Check:
Correct name and assert with == 12 = def test_multiply():\n assert multiply(3, 4) == 12 [OK]

Quick Trick: Test functions start with test_ and assert expected == actual [OK]

Common Mistakes:

MISTAKES

Wrong expected value in assert
Wrong function name prefix
Using = instead of == in assert
