Include functional test cases in a test suite

Includes a list of functional test cases in a test suite. If the test suite is locked, you can call this operation only if you have the owner or edit access. Because test cases can't be shared between test suites, you can't use functional test cases that are already part of other test suites. If you do that, the operation fails, and you need to create the test cases again and rerun this operation. The operation responds with a partial-success 207 response that consists of two arrays, successes and failures. The successes array lists unique identifiers of functional test cases included successfully, whereas the failures array provides details on any remainders that failed.
