+Unit test: `testHLTFiltersDQMonitor`
+------------------------------------
+
+Test of the DQM plugin `HLTFiltersDQMonitor`.
+
+  - To run the test via `scram`
+    ```sh
+    scram build runtests_testHLTFiltersDQMonitor
+    ```
+
+  - To run the test without `scram`
+    ```sh
+    LOCALTOP="${CMSSW_BASE}" "${CMSSW_BASE}"/src/DQMOffline/Trigger/test/testHLTFiltersDQMonitor.sh
+    ```
+
+  - To show info on command-line arguments of `testHLTFiltersDQMonitor_cfg.py`
+    ```sh
+    python3 "${CMSSW_BASE}"/src/DQMOffline/Trigger/test/testHLTFiltersDQMonitor_cfg.py -h
+    ```
+
+  - To execute cmsRun with `testHLTFiltersDQMonitor_cfg.py` (example)
+    ```sh
+    cmsRun "${CMSSW_BASE}"/src/DQMOffline/Trigger/test/testHLTFiltersDQMonitor_cfg.py -- -t 4 -s 0 -o tmp.root -n 100
+    ```
+
+  - To create a bare ROOT file from the DQMIO output of `testHLTFiltersDQMonitor_cfg.py`,
+    run the harvesting step as follows
+    ```sh
+    cmsRun "${CMSSW_BASE}"/src/DQMOffline/Trigger/test/harvesting_cfg.py -- -i file:tmp.root
+    ```
