Is it possible to Link new Test Cases to Existing Test Plans using the MSO2RQM Excel and Word Import Utilities?
Yes, this is possible.
The caveat of linking new Test Cases to an existing Test Plan is that the Test Plan is the parent of the Test Case, and therefore contains the link.
Accordingly, it is necessary to not only import the new Test Cases from Microsoft Excel to IBM Rational Quality Manager, but it is also necessary to update the existing Test Plan's XML to include a link to these Test Cases.
In a normal REST implementation, this would not be feasible, but Rational Quality Manager's REST API allows for updating of test asset fields.
The sample syntax below must be implemented in the CFG file to accomplish this link.
In the above example, "urn:com.ibm.rqm:testplan:12" represents a valid internal or external ID of an existing Test Plan.
WARNING: The ability to update specific fields is not consistent across all test assets. A normal REST implementation will overwrite all fields in the existing test asset, and replace them with the fields provided in the import. The concepts in this technote have been validated to work against Test Plans, but users should test and verify this behavior before using it on production data. Failure to do so could result in the tool overwriting existing test assets.
