Test case development

7layers has been developing test cases for the wireless industries for many years and at the very earliest development stages of new technologies. Thanks to the structure of the 7layers group our development services can be complemented with strictly separate validation services.

For test cases development we proceed as follows

  1. Description of test cases in prose
  2. Writing test cases with help of
    • Formal test notations (e.g. TTCN), or
    • Conventional programming languages (e.g. C, C++, Visual.Net)
  3. Implementation of test cases in special test systems
    of 7layers used as development environment

7layers has developed test cases for radio, protocol, interoperability and field test specifications. We verified and validated for example the first FDD-7 protocol test cases for the LTE technology.

Test case development for products
with wireless connectivity

Industries developing and/or employing products with integrated wireless connectivity often face problems formerly unknown to them.  In order to make the upcoming M2M world a success, requirements regarding safety, security and interoperability have to be taken care of. Depending on the service you are planning to offer, standard test specifications and test cases may not be sufficient. 7layers can help in such cases with the development of customized test cases and even test specifications.  

Early test case development supporting
your leading-edge product development

Product developers benefit from being able to conduct testing early, before official test specifications and test case releases from standardization groups are available. Based on our experience and objectivity 7layers supports product and test equipment manufacturers with early test case development. These test cases generally corresponded very closely to the official versions released by standardization groups later on.
