Mobile testing types in Testing Fundamentals - Test Execution Trace

Test Overview

This test simulates checking different types of mobile testing: functional, usability, and performance testing. It verifies that the mobile app behaves correctly, is easy to use, and performs well under load.

Test Code - unittest

Testing Fundamentals

import unittest

class MobileTestingTypes(unittest.TestCase):
    def test_functional(self):
        # Simulate checking a button click works
        button_clicked = True  # Assume button click simulated
        self.assertTrue(button_clicked, "Button should be clickable")

    def test_usability(self):
        # Simulate checking if app navigation is intuitive
        navigation_easy = True  # Assume navigation tested
        self.assertTrue(navigation_easy, "Navigation should be easy")

    def test_performance(self):
        # Simulate checking app response time under load
        response_time_ms = 450  # Simulated response time
        self.assertLessEqual(response_time_ms, 500, "Response time should be under 500ms")

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

Execution Trace - 5 Steps

Step	Action	System State	Assertion	Result
1	Test starts	Test framework initialized	-	PASS
2	Runs test_functional to check button click	Simulated button click state is True	Assert button_clicked is True	PASS
3	Runs test_usability to check navigation ease	Simulated navigation_easy state is True	Assert navigation_easy is True	PASS
4	Runs test_performance to check response time	Simulated response_time_ms is 450	Assert response_time_ms <= 500	PASS
5	All tests completed	Test suite finished with all passes	-	PASS

Failure Scenario

Failing Condition: If the button click simulation returns False

Execution Trace Quiz - 3 Questions

What does the test_functional verify in this mobile testing example?

A That the response time is under 500ms

B That the app navigation is easy

C That the button click works correctly

D That the app installs successfully

Key Result

Testing different mobile testing types separately helps catch specific issues early, like functionality, usability, and performance problems.
