Test Automation

We increase the performance of your QA through automated testing on real devices in frontend, backend and through monitoring. 

Efficient and stable
development cycles

Automated testing can be integrated into different phases of software development. We will find the right time and the right solution for you.
Test automation can save time and money. Our tests interact with your system on real devices and simulate user input. Errors are detected in real time and you will receive the results right away. This ensures more stable development and maximum quality for your product. 

Test Automation Pyramid. Code level - unit tests - test review. API level - integration & system tests - load & performance tests, functional API tests, API monitoring. GUI level - E2E tests - regression tests, data-driven tests, end-to-end monitoring


Test Automation on all levels

Test methods at different levels of the test pyramid ensure structured and cost-efficient QA. At the code level, unit tests can be used to quickly isolate and check individual functions. At the API level, integration tests and system tests provide information on whether all interfaces work and the quality of performance is ensured. At the GUI level, user interaction is simulated and the overall availability and performance of the system is monitored by end-2-end tests.

GUI Testing

Do you want to improve your QA processes sustainably and save time and costs? Our GUI tests give you insights into what your users think, while we record the performance of your product in real time.  

Through Test Automation more tests can be carried out in less time. This leads to an increase of test coverage, because scenarios can be tested that could be overlooked manually or not covered due to time constraints.

GUI Testing

Long-term time and cost savings
The tests can be carried out quickly and repeatedly, allowing faults to be detected and rectified at an early stage.

Stopwatch time icon

Fast execution
Automated tests can process large amounts of data faster compared to manual tests and perform complex calculations.

Path Fork icon

The tests can be run in parallel on several devices and are not tied to sequential execution.


Dedicated & real devices
Realistic factors such as network speed and hardware properties can be integrated through tests on selected devices.


GUI Testing

The ideal time for use

Regression tests

By automated regression tests, testers can focus on complex scenarios and exploratory testing. This improves test quality and allows potential problems to be investigated more thoroughly.

of structured content

GUI tests are suitable for content-rich apps and websites in which the individual areas are structured in the same way, for white label solutions or for testing the same app/website in different languages.
Data-driven tests
GUI testing is worthwhile for test cases with lots of different input data, as the consistent and fast execution significantly increases test coverage.

GUI Testing

Our most frequent use cases

We use GUI testing particularly for the QA of media libraries, in e-commerce, for newspapers, in the tourism industry or for our partners in public transport.

API & Integration Testing

You don't develop all the interfaces of your system yourself? Is your system based on numerous microservices? And the external interfaces have a negative impact on customer feedback? Our API and integration tests will help you to ensure that the API delivers the right data and responds appropriately to requests. 



API & Integration Testing

Load- & Performance-Testing

Suitable methods

Stress Testing

Capacity tests gradually increase the load to find the system limits. Small steps provide more accurate results.



Soak Testing

Detect long-term stability and performance: Through continuous testing under constant load, long-term problems such as memory leaks and bottlenecks in the database can be detected and rectified.



Spike Testing

Simulate advertising campaigns by generating a peak load. The system is tested for sudden load changes and its performance to check its resilience. This prevents your users from bouncing.




End-to-End Monitoring

Are you currently registering system failures mainly due to customer complaints? Do you lack insight into the functionality of all system components and any irregularities? In end-to-end monitoring, we provide you with an insight into your application for early error detection.
