Unit Tests for Main method

Posted on by AnawI

Hello all :)

So i have a class with three methods , main() , construct(), & calc() .

I wrote a test class and in there set up unit tests for all of the branches in calc() & one additional test for the construct method. And with that leaving me with a point to how to test the main method?

In there I have just basic code.

So this is maybe dumb but any suggestions on how to test this class without duplicating the code from the test method for calc?

 public static void main(Args _args)
    {
        ProcessClass obj = ProcessClass::construct();
        obj.calc(_args);
    }

I have the same question (0)

Hi,

By testing the main method do you mean executing it?

To execute the main method, you can create an action menu item and specify the class for the main method on it or you can directly execute this class using the following URL in your browser:

Regards,

Kamal

Running main() method from a test class is trivial: ProcessClass::main(new Args()).

But the question is what you would test by it. What would be the "evaluation" part of your unit test?

If you know what you want to test, then do it. If you don't know, ask yourself about the value of this test. Isn't it just to get a higher number of code coverage and not about bringing business value?

If you want to test that main() calls calc() but not to actually execute logic in calc(), you would need something like a test stub. The currenct implementation would require ProcessClass::construct() to return the test stub instead of the actual ProcessClass class instance. It can be done, but it's quite cumbersome without any mocking framework.

It again brings the question of the value of the test. You may end up with a lot of work just to run a test that gives you little information.
