For developers of all kinds of software, testing and verification are crucial parts of the development process. Testing serves a number of purposes: It ensures software complies with technical requirements, meets business needs and is free of errors. When developing complex, embedded software, many development teams choose to utilize automated regression testing.

Often, new bugs emerge while software is still being developed. When programmers make changes to software to fix errors that have been identified, this can sometimes cause functions that were previously working properly to experience new problems.

As a result, every change made to embedded software during its development necessitates additional testing.

Automated regression testing is a powerful tool that can be used in such situations. Regression testing, also known as verification testing, is the process of analyzing software after a change has been made. In addition to ensuring an error has been fixed, regression testing involves retesting existing components of the software to make sure no new bugs have been created.

The testing process, which can be both repetitive and time-consuming, is also subject to human error. As a result, many development teams choose to utilize automated regression testing solutions. Automated regression testing enables tests to be run quickly and repeatedly, while developers continue working on a project. Because it is automated, it can test and retest the same code many times, as changes are made.

For complex embedded systems, such as aerospace software, military software, medical software, railway software, automotive software and industrial control software, automated regression testing can be an indispensable development tool.
