Add test for EDM persistency for Acts
Recent developments showed that issues with EDM persistency may present only at runtime. And previous experience showed that there may be problems in reading persistified EDMs from AOD, that will go totally undetected without some quick early test
This test checks that:
- EDM can be persistifies successfully
- Persistified EDM can be properly read back from AOD, both with Acts Analysis algorithms and IDPVM
We have in place an ART test that persistifies Acts Clusters and then runs IDPVM, but I'd like to catch this kind of problems at the MR level instead of waiting for nightly to be made and ART tests to run (and crash misteriously)
