What Is Integration Testing?

Integration testing in DevOps involves validating the interactions and interfaces between different components or systems to ensure they work seamlessly together. It is an essential part of the continuous integration and delivery pipeline, helping identify integration issues early in the software development process.

Integration testing can be both black box and white box. In black box integration testing, the internal logic of the components being tested is not known, focusing on inputs and outputs. In white box integration testing, the internal structure is considered, evaluating how components work together based on their internal logic.

Selenium tests can be both integration tests and functional tests, depending on how they are designed and what aspects of the application they validate. Selenium is often used for end-to-end testing, which inherently involves testing integrated components.

Selenium is a widely used tool for web application integration testing and can be enhanced with tools like Parasoft Selenic. Another tool that supports web application integration testing is Parasoft SOAtest. It allows testers to automate interactions with web applications, ensuring that integrated components work seamlessly together.

Tools like Parasoft C/C++test are commonly used for integration testing in embedded systems, ensuring that individual software components work together seamlessly.
