Performance test planning in Testing Fundamentals - Test Execution Trace

Test Overview

This test plans a performance test to check if a website can handle 100 users loading the homepage simultaneously within 5 seconds.

Test Code - unittest

Testing Fundamentals

import unittest
from performance_testing_tool import PerformanceTester

class TestHomepagePerformance(unittest.TestCase):
    def test_homepage_load_under_5_seconds(self):
        tester = PerformanceTester(url="https://example.com/homepage")
        tester.set_user_load(100)
        tester.set_max_response_time(5)  # seconds
        result = tester.run_test()
        self.assertTrue(result.passed, f"Performance test failed: {result.details}")

if __name__ == "__main__":
    unittest.main()

Execution Trace - 6 Steps

Step	Action	System State	Assertion	Result
1	Test starts	Test framework initializes the test case for homepage performance	-	PASS
2	PerformanceTester instance created with URL https://example.com/homepage	Performance test setup ready with target URL	-	PASS
3	Set user load to 100 simultaneous users	Test configured to simulate 100 users	-	PASS
4	Set maximum acceptable response time to 5 seconds	Performance threshold defined	-	PASS
5	Run performance test	Simulated 100 users load the homepage concurrently	Check if all responses are within 5 seconds	PASS
6	Assert test result passed	Test result received from performance tool	Assert that result.passed is True	PASS

Failure Scenario

Failing Condition: The homepage response time exceeds 5 seconds under 100 user load

Execution Trace Quiz - 3 Questions

What does the test verify in this performance test plan?

A Homepage content is correct

B Homepage layout is responsive

C Homepage loads within 5 seconds for 100 users

D Homepage links are clickable

Key Result

Always define clear performance goals like user load and max response time before running tests to measure system capacity effectively.
