Test t_AlignDet_AlephTPC_load failing in dev4

[andresailer]

Check duplicate issues.

• Checked for duplicates

Goal

The test should pass
It fails because under the circumstances described below
There is the line

12: Info in <TGeoManager::CloseGeometry>: 189 nodes/ 24 volume UID's in Detector Geometry

But the test wants, one more node and volume

190 nodes/ 25 volume UID's in Detector Geometry

Operating System and Version

el9

compiler

gcc13

ROOT Version

6-32-patches

DD4hep Version

master

Reproducer

The test fails when building the examples separately from the rest of DD4hep.
But it passes when building DD4hep with DD4HEP_BUILD_EXAMPLES.

Additional context

No response

The problem seems to be that the libAlignDetExample.so library is loaded from DD4hep on cvmfs, and not from the examples we build ourselves.

I should probably fix the testing of DD4hep in the LCG stacks, so that it doesn't install the example libraries.

[MarkusFrankATcernch]

I think so. If I remember correctly this test had to be changed after the fixes I introduced for Ben:
#1287
Hence the additional volume actually is an assembly.

[andresailer]

Thanks! That explains that, dev4 has DD4hep 01-29.

dev4 test is passing again.

Changed the way tests are done in the LCG nightlies. Examples are build separately and their libraries or executables are no longer deployed to cvmfs.
