Spring validation fix

Question

I have validator validating, for instance, input data. It gets object product (class Product) created with default constructor. One of Product fields is description, and it has @NotNull annotation.

When I run test it fails obviously and shows NullPointerException. I can surround part of code where NullPointerException was thrown with if-else like this

if(description!=null){
 // product validation
}else{
  errors.rejectValue("description", errorCode, defaultMessage);
} 

That works, but i need something else, maybe using annotations.

Answer 1

You con use something like Mockito to create a mock of the BindingResult that has a method hasErrors() to check for any errors.
