[UT coverage] How can the industry improve QT code coverage

[xurongqin]

Hi
Thanks for reply on my question. Now we have a complete QTest framework in out QT application, including many metrics on it. But R&D found it was hard to write the UT since they sometimes felt that it was not smooth enough to cover all of the classes.
Now in our QT application, we found that refactor the code by the MVC (Model-Viewer-Controller) design to decouple the classes might be also a possible way to help the R&D to write the unit test coding since some classes did not well follow the MVC design.

If you have more detailed idea on it, pls share more information with us.

Refactoring your code into an MVC design might be a good way to allow implementing unit tests more easily, since the data model is not tightly coupled to the UI in this case. You can test the model using a command line program since the model does not require a user interface.

Depending on how deeply you want to refactor, you could even package your model into a separate library that could allow testing outside of your application.
