Test result publishing in PyTest - Test Execution Trace

Test Overview

This test runs a simple function and publishes the test result using pytest's reporting. It verifies that the function returns the expected output and that the test result is correctly reported as pass.

Test Code - pytest

PyTest

import pytest

def add(a, b):
    return a + b

def test_add():
    result = add(2, 3)
    assert result == 5

Execution Trace - 4 Steps

Step	Action	System State	Assertion	Result
1	Test starts	pytest test runner initializes and loads test_add function	-	PASS
2	Calls add(2, 3)	Function add executes and returns 5	-	PASS
3	Assert result == 5	Test checks if returned value is 5	assert result == 5	PASS
4	Test result published by pytest	pytest records test as PASSED in test report	Test outcome is PASS	PASS

Failure Scenario

Failing Condition: Function add returns incorrect result, e.g., add(2, 3) returns 4

Execution Trace Quiz - 3 Questions

What does the assertion in the test verify?

A That the test runner starts

B That add(2, 3) returns 4

C That add(2, 3) returns 5

D That pytest publishes the test report

Key Result

Always include clear assertions in your tests so the test runner can publish accurate pass/fail results.
