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

"a", "b" }, request.getLocale()));

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.
