TrafficControl: Integrating QtTest Into TrafficControl

After some hours looking at official Qt Documentation, internet forum posts and blogs, I found out how to add Qt Tests to the project, and it is quite easy!

A separate folder named test was created for the test code, where I added a C++ file with the name "tst_traffic.cpp".

The project file gets a debug clause (build commands that are only applied for debug builds):
When running QMake the next time for debug builds, the file main.cpp will be removed from sources. Instead the file tst_traffic.cpp will be added to the sources. Also, the testlib is loaded.

The test cases are listed as private slots and implemented as functions. The QVERIFY macro is used for the verdict.

The test report is shown below.

The next blog posts will cover the new test cases. The target code will be developed in parallel, since I need to change it to be more testable. I'll also use Test Driven Development, which I'll describe in the next blog post.
