Software testing is an indispensable step for robust and sustainable software development. For this purpose, we implemented continuous integration by adding an automated unit testing workflow into the library's repository. latest major versions of Python (3.6 -3.9). The current version of ChemPlot successfully passes all the unit tests. Moreover, the unit tests are packaged with the library so that the users can verify their installations locally. Furthermore, the automated tests are build and run when a new change is pushed into the main repository.
