Is there a Java unit-test framework that auto-tests getters and setters? [closed]

Answer 1

I created the OpenPojo project for solving this exact problem.

The project allows you to validate:

• Enforce Pojo coding standard (i.e. All fields private, or no native variables, ...etc)
• Enforce Pojo behaviour (i.e. setter does JUST setting, no transformation, etc)
• Validate Pojo Identity (i.e. Use annotation based equality & hashcode generation)

See Tutorial

Answer 2

I'm not aware of any readily available library or class that does this. This may mainly be because I don't care as I am on the side of strongly opposing such tests. So even though you asked there must be a bit of justification for this view:

I doubt that autotesting getters and setters benefit your code quality or your coverage: Either these methods are used from other code (and tested there, e.g. 100% covered) or not used at all (and could be removed). In the end you'll leave getters and setters in because they are used from the test but nowhere else in the application.

It should be easy to write such a test, e.g. with Apache Commons BeanUtils, but I doubt you really need it if you have good tests otherwise.

Answer 3

I've done something like that. A simple java class that takes an object and test all the getters and setter methods. http://sourceforge.net/projects/getterandsetter/

I do think you should avoid getter and setter methods as much as possible, but as long as they're around and it takes two lines to test them, it's a good thing to do it.

Answer 4

I'll favor OO design over code coverage, and see if I cannot move those fields to the class that needs them. So I would try to see if those getters and setters can be removed, as suggested before. getters and setters are breaking encapsulation.
