-    export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:$(pwd)/tests
-
-Secondly it is also possible to explicitly load the library via `ROOT` in the
-script by adding the following lines *after* the imports from `__future__`
-
-```python
-import os
-BUILD_PATH = os.getcwd()
-
-import ROOT
-ROOT.gSystem.Load(os.path.join(BUILD_PATH, 'tests/libTestDataModel.so'))
