0This test simulates the test automation pyramid by running three types of tests: unit, integration, and UI. It verifies that each test level passes successfully, showing the pyramid's principle of many fast unit tests, fewer integration tests, and even fewer UI tests.
import unittest class Calculator: def add(self, a, b): return a + b class TestCalculator(unittest.TestCase): # Unit test def test_add_unit(self): calc = Calculator() self.assertEqual(calc.add(2, 3), 5) # Integration test (simulated) def test_add_integration(self): calc = Calculator() result = calc.add(10, 20) self.assertEqual(result, 30) # UI test (simulated) def test_add_ui(self): # Simulate UI input and output input1 = 7 input2 = 8 calc = Calculator() output = calc.add(input1, input2) self.assertEqual(output, 15) if __name__ == '__main__': unittest.main()
| Step | Action | System State | Assertion | Result |
|---|---|---|---|---|
| 1 | Test starts - unittest framework initializes | Test runner ready to execute tests | — | PASS |
| 2 | Runs unit test test_add_unit: creates Calculator instance and calls add(2,3) | Calculator instance created, add method called with inputs 2 and 3 | Check if result equals 5 | PASS |
| 3 | Runs integration test test_add_integration: calls add(10,20) | Calculator instance used, add method called with inputs 10 and 20 | Check if result equals 30 | PASS |
| 4 | Runs UI test test_add_ui: simulates UI inputs 7 and 8, calls add | Simulated UI inputs processed, add method called with 7 and 8 | Check if output equals 15 | PASS |
| 5 | All tests completed | Test report generated showing 3 tests passed | — | PASS |
