Software development is a lengthy and complex process in which the quality of the product to be developed plays a decisive role. Because the software development process involves various stakeholders and is an iterative process, quality assurance measures must be taken in order to deliver a product that meets the requirements of the customer. One of these quality assurance measures is software testing, which is used to validate the software in relation to its intended use.

In this paper to the already held presentation the generic term of the software tests does not stand in the foreground, instead an insight into the subset of the regression tests is given. Regression tests differ in their basic mode of operation from the widely used module and integration tests, but are nevertheless a cornerstone of software quality assurance.
