int4 IFTT is delivered with API service that can be used in order to perform testing from external testing suites like Microfocus UFT and others. The API can be also called locally from custom SAP ABAP programs to speedup or automate testing operations.
The test case execution API is exposed as:
Both synchronous and asynchronous execution of test cases is possible with IFTT API.
Alternatively you can record the Int4 IFTT API invocation as an UI script:
It allows to pass the test case numbers or scenario numbers.
Passing scenario gives more flexibility as the scenario can be called for example 'SAP PI unit tests for Sales interfaces' and can be setup once in external testing software. The content of scenario can be continuously managed in IFTT (new test cases can be added or removed), while the integration with external software stays as is.
