I have User entity and I try validate field password for length in my test.
My User Class:
I realize the post is bit old and probably resolved. Just wanted to updated anyway if someone else encounter the same issue. As Mufanu added in the comment this will resolve if we add message attribute in the annotation
@not null works fine without message
@Size(min = 5, max = 6, message = "size must be between 5 and 6")
private String password;
