API API Test Automation

Question 1

Which Python library is commonly used for writing automated REST API tests?

Accepted Answer

Requests + PyTest

Answer

The `requests` library handles HTTP calls while `pytest` provides the test framework, making them the standard Python combo for API test automation.

Question 2

What is the purpose of a test fixture in API automation frameworks?

Accepted Answer

Set up and tear down test preconditions consistently

Answer

Fixtures prepare the environment before tests run (setup) and clean up after they finish (teardown), ensuring consistent, isolated test conditions.

Question 3

What does 'data-driven testing' mean in the context of API automation?

Accepted Answer

Running the same test logic with multiple sets of input data

Answer

Data-driven testing separates test logic from data, running the same test scenario with different inputs from an external source like CSV or JSON.

Question 4

Which concept in API test automation ensures tests do not depend on each other or share state?

Accepted Answer

Test isolation

Answer

Test isolation ensures each test runs independently with its own setup and teardown, preventing one test's state from affecting another's result.

Question 5

What is a mock server used for in API test automation?

Accepted Answer

Simulating an API dependency without calling the real service

Answer

A mock server simulates the behavior of a real API dependency, allowing tests to run without relying on external services that may be unavailable or slow.
