Integration Test
An integration test is a type of software test that focuses on checking the interaction between multiple components of a software system. It involves executing the entire software system as a single unit, simulating the user's interactions, and verifying that each component behaves as intended.
Example:
Imagine a software system for online shopping. An integration test would verify that when a user adds an item to their cart and proceeds to checkout, the system correctly calculates the total price and updates the cart and checkout page accordingly.
Key characteristics of integration tests:
They are broader than unit tests, encompassing multiple components interacting with each other.
They focus on verifying the entire workflow of a software system, including interactions between multiple components.
They are often used after unit tests to ensure that individual components are working correctly.
Importance of integration tests:
They help to identify and fix defects early in the software development lifecycle, preventing them from reaching production.
They ensure that the software system functions as intended and meets the desired user requirements.
They provide valuable feedback for improving the overall quality and stability of the software
