How to unit test @ModelAttribute in Spring MVC controller

[Nitesh Patel]

Hi All,
I am trying to develop unit test for below Spring MVC controller's method using Junit but I could not figure out how can I unit test the @ModelAttribute. Can anyone please guide me ?

	@RequestMapping(value="addperson.html",method=RequestMethod.POST)
	public String submitPerson(@ModelAttribute("person") Person person,BindingResult result){
		
		personValidator.validate(person,result);
		if(result.hasErrors()){
			return null;
		}else{
			return "persons";	
		}
		
	}

Regards,
Nitesh

How about in your unit test just doing

Person person = new Person();
// set person values
controllerInstance.submitPerson(person, …...

Now the BindingResult object is a different matter. You have to instantiate one or create a mock of one. BindingResult is an interface, and there are implementations. Here is the Javadoc for it
http://static.springsource.org/spring/docs/2.0.x/api/org/springframework/validation/BindingResult.html

Good Luck
