Testing early on and throughout the development cycle reduces the risks that affect time to market, cost and software quality. By exercising components (application components, devices and services) at the beginning of the development cycle in a runtime environment, and by continuing to test, as components are refined, developers can be assured of continuous Software Communications Architecture (SCA) compliance up to development cycle completion. Spectra CX SCA Test can be used to test the software aspects that have been hand written, generated automatically using a Spectra CX Code Generator, or generated automatically using a 3rd party tool. Developers benefit from fully automated testing of all aspects of the SCA specified interfaces for each component. These slides will demonstrate the steps for unit testing the standard SCA interfaces of an SCA component with Spectra CX SCA Test. Topics will include: introduction to the Spectra CX unit testing framework; generation of standard unit tests; execution of unit tests on-host and on-target; and creating custom test cases.
