The class GlobalObjectMapRecord is part of the RAW data, and any changes must be backwards compatible. In order to ensure it can be read by all future CMSSW releases, there is a TestGlobalObjectMapRecordFormat unit test, which makes use of the TestReadGlobalObjectMapRecord analyzer and the TestWriteGlobalObjectMapRecord producer. The unit test checks that the object can be read properly from
- a file written by the same release
- files written by (some) earlier releases
If the persistent format of class GlobalObjectMapRecord gets changed in the future, please adjust the TestReadGlobalObjectMapRecord and TestWriteGlobalObjectMapRecord modules accordingly. It is important that every member container has some content in this test. Please also add a new file to the https://github.com/cms-data/DataFormats-L1TGlobal/ repository, and update the TestGlobalObjectMapRecord unit test to read the newly created file. The file name should contain the release or pre-release with which it was written.
