Comparing values (equality, inequality) in PyTest - Test Execution Trace

Test Overview

This test checks if two values are equal and if two other values are not equal using simple assertions in pytest.

Test Code - pytest

PyTest

import pytest

def test_compare_values():
    a = 5
    b = 5
    c = 10
    d = 20

    assert a == b, "Values a and b should be equal"
    assert c != d, "Values c and d should not be equal"

Execution Trace - 5 Steps

Step	Action	System State	Assertion	Result
1	Test starts	pytest test runner initialized	-	PASS
2	Assign values a=5, b=5, c=10, d=20	Variables set in test function	-	PASS
3	Assert that a equals b	a=5, b=5	Check if a == b	PASS
4	Assert that c does not equal d	c=10, d=20	Check if c != d	PASS
5	Test ends successfully	All assertions passed	-	PASS

Failure Scenario

Failing Condition: If a and b are not equal or c and d are equal

Execution Trace Quiz - 3 Questions

What does the assertion 'assert a == b' check?

A If a is less than b

B If a and b have the same value

C If a is greater than b

D If a and b are different types

Key Result

Use clear and simple assertions to compare values. Always include a helpful message in assertions to understand failures quickly.
