But what if we want to call the main () method from somewhere in our program? And we want to execute its main method from the command line via Maven. In order to do this, we can use the exec-maven-plugin. To be more specific, the exec:java goal from this plugin executes the supplied Java class with the enclosing project's dependencies as the classpath. To call a method in Java, write the method name followed by a set of parentheses (), followed by a semicolon (;). A class must have a matching filename (Main and Main.java). Running the main () method means running the run () method which can take a long time and changes the scope of the test.

This is an useful way to reuse the same code over and over again. IMO the best way to test the main method is by having the main method do absolutely nothing but set up the world and kick it off.
