Increasing complexity of systems means that more and more tests are necessary. However, too few tests are often created. devmate is a new startup product developed as part of an EU research project that supports the (semi-)automatic generation of unit and integration tests. On the one hand, this improves the quality of the tests and, on the other hand, relieves developers of the boring writing of unnecessary unit test code. In the presentation, the methodological background of this new development will be presented and a live insight into the product and code generation will be given.
