Innovative technology solves problems with software tests through an AI-supported and agile automation solution

Today’s software systems are complex, and many internal dependencies remain unclear. As a result, changes to the software lead to undesired side effects that often go unnoticed, i.e. an existing and already tested functionality is impaired. In order to prevent such regressions, software must be tested again and as completely as possible after each change. Previous automation solutions only allow manually programmed tests to run automatically. This is usually not economical due to the high effort involved in creating and maintaining the tests. Against this background, 3/4 of all regression tests in practice are executed manually instead of automatically. This is why software testing and test automation are often described as the biggest bottleneck in software development.

retest wants to solve this problem with the help of a new testing paradigm called Difference Testing. The retest software automatically detects changes and makes automated tests robust and easy to maintain by means of a so-called 1-click maintenance. Using AI, retest also enables tests to be generated automatically, thus reducing time and costs.

“The HTGF investment allows us to make our approach available as an open source product to a wide range of developers and testers. Our goal is to establish this paradigm as a new standard in test automation,” says Dr. Jeremias Rößler, CEO and founder of retest GmbH.
retest was founded by a technology-driven team. Martin Vietz, co-founder and CTO has more than 10 years of experience as a software developer and technical project manager. Jeremias Rößler holds a doctorate in the application of AI in test automation and software engineering.

Daniela Bach, Investment Manager of High-Tech Gründerfonds: “retest solves a major problem in software development and thus addresses a large market potential. The innovative retest solution and the strong founders convinced us, and we are very happy to welcome the team to the HTGF portfolio”.
