Testing and integration –
full service for a fault-free system.

We believe a system is more than the sum of its parts. For an integral system to function properly, the interactions between all components are crucial. As your independent development partners, our engineers and technicians can implement testing projects for you throughout the V-model. We verify and validate complex electronic components, modules and systems. From component tests to module tests and integration tests to system tests, thanks to our expertise in the planning, automation and implementation of test procedures across various domains, we stand ready to assist as your dependable partner. Automated testing allows us to increase the depth and breadth of test procedures and guarantee the maximum level of quality assurance. In our work, your requirements for the system take priority. With our own lab spaces, workshops and testing infrastructure, we meet all preconditions for successful implementation of your testing processes.

 

Our testing and integration services

Inspecting individual components in isolation forms the basis of our subsequent integration and system tests. This allows us to exclude external influences and interactions during testing. Our ASAP experts examine whether components meet all functional and non-functional requirements. This involves testing components at their interfaces against the specifications – which makes complete specifications essential. We produce detailed test reports for you to demonstrate technical operability and show that components meet all specific requirements for your individual use case.

Integration testing is an important stage in the development of robust and fault-free applications. To ensure the integral system functions properly, our specialists combine and test independent modules and subsystems. This involves connecting control units, actuators and sensors. We commission individual modules within an integrated network and make sure they function properly. Our employees measure and analyse the behaviour of individual control units up to protocol level to ensure complete, end-to-end reporting. The foundation of efficient integration testing and software testing is a specification set down in detail. Drawing on our expertise from past projects, we can ensure your components are integrated quickly and efficiently in the vehicle. 

To ensure an entire system is fault-free, we define individual system requirements in accordance with your wishes. We develop test methods and processes and ensure comprehensive test management. To ensure efficient quality assurance processes, we offer automated testing according to your individual requirements. We use tools such as EXAM, CANoe, CANape and ecoTest to do so and also conduct text and image analyses. Our ASAP experts integrate, configure and code the individual components and conduct vehicle integration tests. In system testing, our engineers and technicians aim to examine whether the integral system fulfils the pre-defined specifications. We document the results of these tests with detailed protocols and test incident reports as well as a final test report.

Whether in the lab or in the vehicle itself, we can conduct testing on networked electronic components for you. Before doing so, we update control unit hardware and software and perform manual and automated testing. In doing so, our engineers and technicians use simulations of physical wire harness conditions. We use CANoe and ODIS tools plus an extensive range of equipment to perform detailed fault analysis. Expertise developed over many years, combined with state-of-the-art technology, enables us to identify flaws up to the bus protocol level. We believe comprehensive fault analysis should be extensive: we investigate causes, isolate issues, verify flaws and take an active role in the rectification process.

ISTQB-certified test specialists.

Whether in relation to software life cycle, software test processes or test management, our employees have in-depth knowledge of software testing. They are trained and certified to ISTQB® Certified Tester Foundation Level (CTFL) – a fixed component of our in-house training offering. As certified software testers, our developers have in-depth testing expertise and have an excellent command of all established standards and processes. This means that, even as software complexity increases, we can ensure the maximum level of quality assurance in your software project and support you from the test phase through to final approval.

 

Boosting efficiency in HMI validation.

Control and display systems represent an important interface between man and machine in vehicles, as the driver sees a wide range of information across several monitors simultaneously. This includes around 17,000 different messages in over 30 languages. As a result, around 600,000 different text variants need to be displayed flawlessly. Manual testing is not suitable for such large-scale validation – it would take too long, cost too much and lack the requisite test depth. Our ASAP experts have developed a specific software solution that automatically tests all information displays. “The software features very precise text and image recognition functions,” explains Tim Bayer, Head of Electronics Development/Control and Display Systems. “Consequently, automated testing is capable of generating images of all displays to be validated using our customers’ design data. These target images are generated in a fully automated process.” As a result, we achieve markedly higher test coverage in a short period of time and react flexibly to any changes the customer might make to their design data.

 

Development edge through white-box testing.

For more efficient validation processes, our developers increase the level of test automation with white-box testing. In contrast to black-box testing, the white-box method provides information on the internal structure of the software to be tested. This means we can draw on code-based validation, which allows us to examine program code before it is applied in a control unit. A decisive advantage of this approach is the ability to begin validation as soon as development is underway. The flexibility, reliability and speed of test automation solutions have already proven a decisive edge in development processes.  White-box testing will allow us to exploit this edge further still.  

 

Verification and validation of power electronics.

From specification and test automation to validation and diagnosis, we offer support in the validation of high-voltage power electronics. We believe efficient and effective testing begins with defining the requirements in detail. Building on this, our ASAP experts specify scenarios, create test catalogues and conduct the actual tests. We use tools such as EXAM to develop automation concepts that enhance efficiency in spite of the expanding scope of testing. Our engineers and developers can conduct manual testing for you at component test stations, in networked HiL simulations and in the vehicle itself. But that’s not all: in coordination with your specialist department, our ASAP experts can validate test results, adjust the diagnosis scope and generate comprehensive reporting. From the conceptual phase through to start of production, as your competent development partner we stand ready to assist with our years of expertise.

Aleatory functional validation.

The increasing diversity and flexibility of vehicle functions is creating additional challenges when it comes to validation. Using artificial intelligence makes it possible to validate complex event chains including the lateral influence of different control units in a comprehensive and time-saving manner. As a capable partner for innovative technologies, ASAP experts have developed a validation method based on reinforcement learning, namely aleatory functional validation. It represents an effective complement to requirement-based functional validation in numerous respects. The self-learning validation method has already been used following a change in US law. This is because US law FMVSS111 required all vehicles sold in the USA since May 2018 to be equipped with a rear-view camera. The key aspect here is that the image must be displayed within a maximum of two seconds of the driver shifting into reverse gear and must not be overlaid with other displays. By developing aleatory functional validation, ASAP was able to provide the perfect solution – a method to validate functions more effectively, more precisely and with a far greater range of scenarios than with conventional methods.

 

Nina Friedrich – Project Manager, Electronics Development.

Emphasising the features: Nina Friedrich and her team are responsible for more than 30 different control units – from air-conditioning and comfort electronics to keyless entry. “As a neutral testing body, my colleagues test the functions of RGB LED modules,” says Project Manager Friedrich. These modules are part of the ambient lighting system and illuminate the vehicle in different colours in the footwells, door areas, centre console and dashboard. “Even before a vehicle is provided to us, we conduct measurements using a system comprising Ulbricht spheres and spectrometers. That allows us to identify colour deviations under the influence of temperature and voltage,” the physicist explains.  “For us, the challenge lies in planning, coordinating and ensuring the proper functioning of control units over the period from pre-series development through to final approval,” says Friedrich.
