Assigns a test suite to a functional test case. You can include a test case in only one test suite. To use the same test case in a different test suite, create the same functional test case again and include it in another test suite. The operation responds with a partial-success 207 response that consists of two arrays, successes and failures. The successes array lists unique identifiers of test suites assigned successfully, whereas the failures array provides details on any remainders that failed.
