TESTING.md

@@ -26,12 +26,15 @@ Build scitran-core image and run automated tests in a docker container:
 * To skip building the image, use `--no-build` (`-B`)
 * To pass any arguments to `run-tests-ubuntu.sh`, use `-- TEST_ARGS`
 
+
 #### Example
 Without rebuilding the image, run only integration tests matching `foo`, use the highest verbosity level for test output and jump into a python debugger session in case an assertion fails:
 ```
 ./tests/bin/run-tests-docker.sh -B -- -i -- -k foo -vvv --pdb
 ```
 
+**NOTE:** The mongodb version is pinned via the `MONGO_VERSION` variable in `tests/bin/run-tests-docker.sh`.
