QSPRpred also takes advantage of continuous integration (CI) not only to run unit tests, but also to frequently run the tutorial code and check consistency of models. Therefore, it is always ensured that upon any modification of the code all tutorials are up to date, all code is working as expected and all reference models return the same expected results. The latter is especially important to guarantee model consistency across different versions of the code and its dependencies by highlighting changes that could lead to past results being unrepeatable.
