Make sure that files with the complete datamodel can be read

• Refactor createEDM4hepFile.py script to facilitate testing. Apart from the obviously different values in the objects, the overall structure is almost unchanged for the output file.
  • The MCVertexRecoParticleLinkCollection has been renamed to the VertexRecoParticleLinkCollection
  • The subdetectorHoleNumbers are also populated for Tracks.

ENDRELEASENOTES

I have refactored the createEDM4hepFile.py script to effectively reset the counter to 0 for every datatype in order to make testing a bit easier, because we won't have global changes in expected values in case some data members are added or removed. With this we can use this script to generate an EDM4hep file for every tag we have and store it somewhere (probably EOS, the same way we do it for podio) and download them on-the-fly for testing to be able to check that we don't accidentally break backwards compatibility with changes to the datamodel.

This is the first part of #358 without the backwards compatibility parts yet, to disentangle the two and to make it possible to tag this part first before adding backwards compatibility tests. In this way the latter will have a clearly reproducible path to regenerating input files if necessary.

For this PR I don't have any more comments, I'll think about the other PR related to backwards compatibility.

Just to confirm, the cppyy version coming with ROOT 6.30.06 is 1.6.2 and with ROOT 6.32.02 is 3.1.2, right?

[tmadlener]

Yes.

It looks like GaudiTesting produces some <DartMeasurement ... XML output that contains the complete test file as a string, which in turn matches the FAIL_REGULAR_EXPRESSION from the test environment. I have disabled this matching for the new tests. Hopefully now everything that we expect to pass should also pass.

[jmcarcell]

Hmm locally I get that is loading GaudiTesting but the tests pass. The last change here doesn't change anything for me, the tests always pass. To remove GaudiTesting from the plugins one can add -p no:gaudi_fixtures -p no:collect_for_ctest -p no:ctest_measurements_reporter to the configuration or to the command. Maybe it's worth to add it but there is some ongoing work for tests right now in Gaudi so these things may change.

[tmadlener]

The tests were always passing. However, the output contained things like getEnergyError (from the test code) which trigger this regular expression
