The `test/` directory of the `HLTrigger/Configuration` package contains
- scripts to copy HLT menus from the `ConfDB` database into CMSSW,
as both `cff` fragments (loadable via `cmsDriver.py`) and standalone `cfg` configurations (usable with `cmsRun`);
- scripts to run tests with these HLT menus
(a version of these tests runs in CMSSW integration buils as the so-called "HLT-Validation" tests);
- a unit test to verify the availability of the EDM input files used in the HLT tests maintained in CMSSW by the Trigger Studies Group
(see `testAccessToEDMInputsOfHLTTests` below).
_Important_ : when the names of the EDM files hard-coded in
`HLTrigger/Configuration/test/cmsDriver.csh` and/or
`Configuration/HLT/python/addOnTestsHLT.py` are changed, make sure to
(1) commit your local changes, and then
(2) execute the script `HLTrigger/Configuration/test/testAccessToEDMInputsOfHLTTests_update_filelist.sh`
in order to update the file `HLTrigger/Configuration/test/testAccessToEDMInputsOfHLTTests_filelist.txt`.
The latter contains the list of files queried by the unit test `testAccessToEDMInputsOfHLTTests` (see below),
which will then be cached in the IB-EOS area at the CERN T2.
---
Unit test: `testAccessToEDMInputsOfHLTTests`
---
This unit test executes `cmsRun` jobs to verify the availability
of the EDM files listed in `HLTrigger/Configuration/test/testAccessToEDMInputsOfHLTTests_filelist.txt`.
To run the unit test via `scram`, execute
```bash
scram b runtests_testAccessToEDMInputsOfHLTTests
```
To run the unit test locally, execute
```bash
cd "${CMSSW_BASE}"/src/HLTrigger/Configuration/test && \
SCRAM_TEST_PATH=. ./testAccessToEDMInputsOfHLTTests.sh
```
The unit test does not modify the content of the file `testAccessToEDMInputsOfHLTTests_filelist.txt`.
The latter can be updated by manually executing the script `testAccessToEDMInputsOfHLTTests_update_filelist.sh`.
- The file `testAccessToEDMInputsOfHLTTests_filelist.txt` lists
the Logical File Name (LFN) of the EDM files used in HLT tests for
(1) the main CMSSW development branches (name format: `CMSSW_[0-9]*_[0-9]*_X`), and
(2) the HEAD of local CMSSW in use.
- The script `testAccessToEDMInputsOfHLTTests_update_filelist.sh` ignores other branches,
as well as local modifications which have not been committed yet.
- The file `testAccessToEDMInputsOfHLTTests_filelist.txt` lists only EDM files which are either
(1) cached in the IB-EOS area at the CERN T2, or
(2) accessible remotely via the redirector `cms-xrd-global.cern.ch`.
Here are the steps one normally executes to update the
EDM input files and the unit test `testAccessToEDMInputsOfHLTTests`.
- Update the input EDM files where needed,
e.g. `addOnTestsHLT.py` and/or `cmsDriver.csh`.
- Test, and commit the changes.
- Run `testAccessToEDMInputsOfHLTTests_update_filelist.sh`
(this will update `testAccessToEDMInputsOfHLTTests_filelist.txt`, if needed).
- Run the unit test (e.g. `scram b runtests_testAccessToEDMInputsOfHLTTests`).
- Commit the changes to `testAccessToEDMInputsOfHLTTests_filelist.txt`, if any.
