Hello,

i am running my unit test but for some reason i am getting a null pointer on this line

[code=java

mav.addObject(
"failLog",
messageSource.getMessage("login.user.fail", new String[] {
"a", "b" }, request.getLocale()));
][/code]

Please find below the method that my unit test will be based on:



Please find below my unit test:



Please see stack trace below:



line 100 for my loginController is shown below:


I am assuming that i need to mock message source. If this is the cause of my exception, how can i mock the messagesource in my unit test please?

However when i run my application it works fine no null pointer, its only when i run the unit test that i get the null pointer exception.

Thanks in advance.

Where is messageSource defined? I don't see it as an instance variable, parameter or local variable.
