Understanding the layers of the Test Automation Pyramid

Which layer of the Test Automation Pyramid typically contains the most tests and runs the fastest?

A Integration tests

B Manual tests

C End-to-end tests

D Unit tests

💡 Hint

Think about which tests check small pieces of code and run quickly.

Unit tests are at the bottom of the pyramid, are the most numerous, and run the fastest because they test small parts of the code in isolation.

Purpose of integration tests in the Test Automation Pyramid

What is the main role of integration tests in the Test Automation Pyramid?

A Test individual functions in isolation

B Test how different modules work together

C Test the entire application from the user interface

D Test performance under heavy load

💡 Hint

Integration tests check connections between parts, not just one part alone.

Integration tests verify that different modules or components work together correctly, which is the middle layer of the pyramid.

Test execution order in the Test Automation Pyramid

Given this test suite execution order, which layer is being tested first?

Testing Fundamentals

def run_tests():
    print('Running unit tests')
    print('Running integration tests')
    print('Running end-to-end tests')

run_tests()

A Unit tests

B Integration tests

C End-to-end tests

D Manual tests

💡 Hint

Look at the first print statement inside the function.

The first print statement shows 'Running unit tests', indicating unit tests run first in the suite.

❓ assertion

advanced

Correct assertion for verifying a unit test result

Which assertion correctly checks that a function add(a, b) returns 5 when called with 2 and 3?

Testing Fundamentals

def add(a, b):
    return a + b

A assert add(2, 3) != 5

B assert add(2, 3) = 5

C assert add(2, 3) == 5

D assert add(2, 3) > 5

💡 Hint

Remember the syntax for equality comparison in assertions.

Option C uses the correct syntax and logic to assert the function returns 5.

Choosing the best test type for fast feedback in CI/CD pipeline

In a continuous integration pipeline, which test type from the Test Automation Pyramid should run first to provide the fastest feedback?

A Unit tests that verify small code parts

B Integration tests that check module interactions

C End-to-end tests that simulate user actions

D Manual exploratory tests

💡 Hint

Think about which tests are fastest and easiest to run automatically.

Unit tests run quickly and provide immediate feedback, making them ideal for early CI pipeline stages.
