Asserts that a every class in the directory (or it's sub directories) has at least one test class. It's assumed that the name of the
test class follows the pattern <code>XxxxxTest</code>, where <code>Xxxxx</code> is the name of the class that is tested. The class
must contain at least one method annotated with {@link Test}. No special class filter applies.

@param baseDir
Root source directory like ("src/main/java").
