Interoperability Test Bed software 1.17.0 Switch to the latest release

Published on: 20/07/2022 Last update: 09/11/2023

Version 1.17.0 of the Interoperability Test Bed software, based on the GITB CWA specifications, is now released. 

This release focuses primarily on the GITB Test Description Language (TDL) and the capabilities of the test bed’s test execution engine. The GITB TDL is extended with several new processing and messaging capabilities that simplify common operations and working with data transformations and templates. In addition, scriptlets, the GITB TDL construct for reusing test steps across test cases and test suites, are now made more flexible by allowing texts and actors to be dynamically set according to their usage context. Finally, the expression language used by GITB TDL steps for simple processing is now upgraded to the latest XPath version leading to expression simplifications and multiple new use cases becoming available.

Apart from the new GITB TDL features, changes in the test bed software include performance improvements, more extensive test suite validation, and most importantly new REST API operations to deploy and undeploy test suites. The new test suite management operations complement the previously available test session operations to further facilitate using the test bed in continuous integration processes for test development.

This new version is online in the Interoperability Test Bed service hosted by DIGIT but is also available for you to setup as a standalone instance. If a standalone instance best matches your needs, the following supporting resources are available:

If you are updating from a previous version, please follow the Test Bed's update guide.
