Integration testing in Rest API - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is integration testing in software development?

Integration testing checks if different parts of a program work together correctly. It tests combined modules to find issues in their interaction.

beginner

Why is integration testing important for REST APIs?

It ensures that different API endpoints and services communicate and work together as expected, catching errors that unit tests might miss.

Name two common approaches to integration testing.

1. Top-down: Test from the top module downwards.<br>2. Bottom-up: Test from the bottom modules upwards.

What is a stub in integration testing?

A stub is a fake module that simulates the behavior of a called component to help test parts of the system before all components are ready.

beginner

How does integration testing differ from unit testing?

Unit testing checks individual parts alone, while integration testing checks if those parts work well together.

What does integration testing primarily focus on?

A Testing individual functions only

B Testing database performance

C Testing user interface design

D Testing how modules work together

Integration testing checks the interaction between different modules or components.

Which of these is NOT a common integration testing approach?

A Top-down

B Bottom-up

C Sideways

D Big bang

Sideways is not a recognized integration testing approach.

In REST API testing, integration tests often check:

A The color scheme of the API docs

B If endpoints return correct combined data

C Only the database schema

D The speed of the internet connection

Integration tests verify that API endpoints work together and return correct combined results.

What is a stub used for in integration testing?

A To simulate a missing module

B To speed up the internet

C To test user input validation

D To style the user interface

A stub simulates a module that is not yet ready to help test other parts.

Which testing type comes after unit testing in the software testing process?

A Integration testing

B System testing

C Acceptance testing

D Performance testing

Integration testing follows unit testing to check combined parts.

Explain in your own words what integration testing is and why it matters for REST APIs.

Think about how different API parts need to work together smoothly.

Describe two common approaches to integration testing and when you might use each.

Consider starting tests from the main module or from smaller parts.
