From individual components to the entire system

Software must be thoroughly tested in every conceivable scenario before it is used in the field. This is how we ensure that reliable systems are provided and avoid costly expenses caused by problems during subsequent phases.

 

We test software by working in multidisciplinary teams and using different methods and techniques and also suitable automation, which allows us to carry out the testing effectively and free of errors.

Individually adapted tests

The tests and methods which we choose are always individually oriented to the challenges and needs which are associated with the specific software. This is achieved by means of close collaboration with developers, stakeholders and quality assurance.

Of course, the test specifications, automation scripts and test protocols are always made available, and reliably document the results.

Forms of software testing

Unit testing

Unit testing involves the testing of individual components or modules of an application in isolation from each other. The majority of classic programming errors can usually be identified in the static code analysis.  The source code is then examined at functional level during dynamic unit testing. Unit testing ensures that each individual component works properly and provides the expected results (input/output analysis). The testing is usually automated.

Integration testing

Integration testing is used to check the interaction and integration of multiple components or modules of an application. The interaction and communication of the different components and functions with each other and between each other are tested during integration testing. Integration tests can basically be carried out manually or automatically, depending on the type of application.

The main focus of our work:

Electronics testing

We develop our own tools, test benches and test strategies in order to check the functionality and quality of components, circuits, PCBs and entire electronic devices. We carry out special measurements in collaboration with certified laboratories. The results are documented in detail, and compared with previously defined requirements.

Component testing

We test and evaluate how powerful and reliable the components of a system are – individually, in combination or even as complete functions of vehicles, machinery or systems, depending on the scope of the project. With appropriate test strategies and automation, we ensure that hardware and software work together without problems and ensure that complete documentation is provided.

Testing overview

A new system must not reach users without fundamental testing – this applies in the automotive sector as well as in other industries, and also electronic systems and all kinds of software.
