Entry and exit criteria in Testing Fundamentals - Build an Automation Script
import unittest class TestEntryExitCriteria(unittest.TestCase): def setUp(self): # Simulate checking entry criteria self.requirements_approved = True self.test_plan_available = True self.test_environment_ready = True # Assert entry criteria self.assertTrue(self.requirements_approved, "Requirements must be approved before testing") self.assertTrue(self.test_plan_available, "Test plan must be available before testing") self.assertTrue(self.test_environment_ready, "Test environment must be ready before testing") def test_execute_tests(self): # Simulate test execution self.tests_executed = True self.defects_logged = False # Assume no defects found self.all_tests_passed = True # Assertions during test execution self.assertTrue(self.tests_executed, "Tests should be executed") def tearDown(self): # Simulate checking exit criteria self.all_defects_fixed = True self.test_coverage_complete = True # Assert exit criteria self.assertTrue(self.all_defects_fixed, "All defects must be fixed before exit") self.assertTrue(self.test_coverage_complete, "Test coverage must be complete before exit") if __name__ == '__main__': unittest.main()
The setUp method checks the entry criteria before any test runs. It asserts that requirements are approved, the test plan is available, and the test environment is ready.
The test_execute_tests method simulates running tests and asserts that tests have been executed.
The tearDown method checks exit criteria after tests finish. It asserts that all defects are fixed and test coverage is complete.
This structure ensures the test phase only starts and ends when the correct criteria are met, following best practices for clear assertions and setup/teardown usage.
Now add data-driven testing to verify entry and exit criteria with different scenarios (e.g., missing requirements approval, incomplete test coverage)
Practice
entry criteria in software testing?Solution
Step 1: Understand the definition of entry criteria
Entry criteria are conditions that must be met before testing begins.Step 2: Differentiate entry from exit criteria
Exit criteria decide when testing ends, not when it starts.Final Answer:
To decide when testing can start -> Option DQuick Check:
Entry criteria = start testing [OK]
- Confusing entry criteria with exit criteria
- Thinking entry criteria fix bugs
- Assuming entry criteria list test cases
exit criteria statement?Solution
Step 1: Identify exit criteria characteristics
Exit criteria define when testing can stop, such as completing all planned tests.Step 2: Evaluate each option
Options A, C, and D relate to preparation or start, not finishing testing.Final Answer:
All planned test cases have been executed -> Option AQuick Check:
Exit criteria = finish testing [OK]
- Mixing setup tasks with exit criteria
- Choosing entry criteria as exit criteria
- Ignoring completion of test cases
Solution
Step 1: Identify entry criteria in the scenario
Testing starts after environment is ready and requirements are frozen, so these are entry criteria.Step 2: Identify exit criteria in the scenario
Testing stops when critical bugs are fixed and test cases executed, so these are exit criteria.Final Answer:
Entry criteria include environment readiness and frozen requirements; exit criteria include bug fixes and test completion -> Option AQuick Check:
Entry = start conditions, Exit = stop conditions [OK]
- Swapping entry and exit criteria
- Ignoring bug fixes as exit criteria
- Confusing frozen requirements as exit criteria
Solution
Step 1: Analyze each exit criteria item
All test cases executed is a valid exit criterion. Test environment cleaned is usually a post-testing task, not exit criteria.Step 2: Consider bug fixing in exit criteria
Requiring all bugs fixed is often unrealistic; exit criteria usually require critical bugs fixed, not all.Final Answer:
All bugs fixed is not necessary for exit criteria -> Option BQuick Check:
Exit criteria need critical bug fixes, not all bugs [OK]
- Assuming all bugs must be fixed to exit testing
- Confusing cleanup tasks with exit criteria
- Ignoring importance of test case execution
Solution
Step 1: Review exit criteria conditions
Exit criteria require 95% test cases passed and all critical defects fixed.Step 2: Compare actual results with exit criteria
Only 90% passed, which is below 95%, so exit criteria are not met yet.Final Answer:
Continue testing until 95% pass rate is reached -> Option CQuick Check:
Exit criteria must be fully met before stopping [OK]
- Stopping testing early when pass rate is low
- Ignoring pass rate in exit criteria
- Confusing entry criteria with exit criteria
