Testing in Scrum sprints in Testing Fundamentals - Test Execution Trace

Test Overview

This test simulates how testing is integrated into Scrum sprints. It verifies that test cases are created, executed, and defects are logged within the sprint cycle.

Test Code - PyTest

Testing Fundamentals

class ScrumSprintTest:
    def __init__(self):
        self.test_cases = []
        self.defects_logged = []

    def add_test_case(self, test_case):
        self.test_cases.append(test_case)

    def execute_tests(self):
        for test in self.test_cases:
            if not test():
                self.defects_logged.append(f"Defect in {test.__name__}")

    def sprint_complete(self):
        return len(self.defects_logged) == 0

# Example test cases

def test_login():
    # Simulate a passed test
    return True

def test_payment():
    # Simulate a failed test
    return False

# Test execution
sprint_test = ScrumSprintTest()
sprint_test.add_test_case(test_login)
sprint_test.add_test_case(test_payment)
sprint_test.execute_tests()
assert sprint_test.sprint_complete() == False, "Sprint should not complete due to defects"

Execution Trace - 6 Steps

Step	Action	System State	Assertion	Result
1	Create ScrumSprintTest instance	Empty test cases and defects lists	-	PASS
2	Add test_login to test cases	test_cases contains test_login	-	PASS
3	Add test_payment to test cases	test_cases contains test_login and test_payment	-	PASS
4	Execute test_login	test_login returns True (pass)	No defect logged for test_login	PASS
5	Execute test_payment	test_payment returns False (fail)	Defect logged for test_payment	PASS
6	Check if sprint is complete	defects_logged contains one defect	Sprint complete returns False	PASS

Failure Scenario

Failing Condition: Sprint complete returns True even when defects exist

Execution Trace Quiz - 3 Questions

What happens when a test case fails during the sprint?

A The test case is removed from the sprint

B A defect is logged for that test case

C The sprint automatically completes

D The test case is ignored

Key Result

Integrating testing within Scrum sprints ensures defects are identified early and the sprint only completes when quality goals are met.
