Testing for embedded systems? Hitex is the perfect test partner

The test requirements for embedded systems have increased dramatically in recent years. Product functions are increasingly shifting towards electronics, and more and more products are being integrated into overarching control structures. For example, a sauna must be able to detect when the stove is covered by a towel. Even the software for window blinds has to be tested if the motor is controlled via a microcontroller. This creates greater requirements for the test process.

The rise in test costs is usually underestimated – and you need a partner

More and more tests are being required and have to be conducted by the development departments in compliance with standardized processes. Today, not every development division is equipped to handle the work this requires – but the test department at Hitex is.

Manufacturers that are new to working with safety functions are the ones that are most surprised by the test requirements and specifications.

Our staff has the training to help you complete tests faster and with more assurance than going it alone. We're also happy to train your development team so that they can even perform the tests themselves in the future. Feel free to test us out too!

Tests are becoming increasingly complex – Hitex has the expertise to build a foundation for you

Developers enjoy being creative. Test is usually another matter, however. Test also requires a certain mindset. Hitex possesses decades of experience to give you a foundation to build upon. We have experienced testers who have internalized all of the requirements and test procedures over many years, backed by a wealth of experience from dozens of projects. Our customers include both large corporations and SMEs. An additional advantage: Hitex offers more than just test as a service; it also understands engineering and sells certain test tools such as TESSY for these purposes. Extensive experience you can rely on in the field of microcontrollers:

How do you benefit?

  • A flexible sales model that lets you purchase just what you need
  • State-of-the-art test
  • Expand your own test knowledge
  • Shorten time-to-market and development times
  • You get fully documented tests and can continue using them as regression tests
  • You don't have to purchase any test equipment
  • You don't necessarily have to invest in training

Large test division

Hitex has a large test division with flexible capacities. Large projects that, for example, require 12 testers for one year are no trouble at all. And we're just as professional when it comes to tests requiring a tester for a week.

Hitex offers integrated, qualified testing – reviews included. No matter whether you need to meet safety standards such as IEC, ISO etc., we have many years of experience working with customers when it comes to handing over the resources and documents, as well as the results, to ensure the progress of the test process is always transparent for our customers. We hand over the knowledge as well as the databases to the customer so that they can carry on with further tests themselves if necessary.

All tests are performed according to the dual control principle, which requires that there always be a tester and a reviewer (both possessing training in compliance with the safety standard).

What is the procedure and what results are achieved?

  1. You provide the code: Simply send us the source code for the C functions that you want to test. It's also useful if you can also provide the specification of the functions and/or detailed comments in the source.
  2. We define the test cases: The test cases are defined on the basis of the classification tree method (CTM), taking into consideration the software module specification and quality requirements for the application.
  3. We generate the test case database: Automated regression tests can be performed using the test case database.
  4. We perform the tests: Hitex performs the specified tests – test by test, function by function. When a test fails or returns suspicious results, we analyze the unexpected behavior to determine the reasons.
  5. We deliver the results: Once the test is complete, we present you with all test results, including the test database and the test case specification, which were created using classification methods.
  6. You review the results: The final step is for you to review the test documentation.
