Should I have failing tests?


Should I have failing tests?

this one helps. When you create unit tests, they should all pass. That doesn't mean that you shouldn't test the "failing" cases. It just means that the test should pass when it "fails."
This way, you don't have to go through your (preferably) large number of tests and manually check that the correct ones passed and failed. This pretty much defeats the purpose of automation.

I think the issue was by ths following , OK got it sorted out...Your gonna love this.
In Eclipse I had a dependency checked out and had branched off master (we are using Git as well) as I was making changes to both projects. When I was running the JUnit runner to the tests it was passing fine because Eclipse was recognizing that it had this dependency however when I was running the maven build it was still using the older version of the dependency...

hope this fix your issue When you build new user object, factory girl assigns to its password given string (it is, to the instance of String class). Every time you do this, you user password is pointing to that object - if you build two users, their password are not only identical - the are the same object.
By using << method youre altering this object and hence you are altering password value for all objects which have been or will be created by this factory.
code :
 u1 = FactoryGirl.build(:user)
 u2 = FactoryGirl.build(:user)

 u1.password.object_id == u2.password.object_id   #=> true!
valid_user.password += valid_user.first_name
factory :user do
    first_name { 'Bob' }
    last_name { 'Shabbadoo' }
    ...

will be helpful for those in need You can use Object.defineProperty to hide a prototype property/method by setting it as non-enumerable.
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/defineProperty
code :
Object.defineProperty(Array.prototype, 'compare', { value : compareFunction } );
Object.defineProperty(Array.prototype, 'compare', { value : Array.prototype.compare } );
Object.defineProperty(Array.prototype, 'compare', { value : compareArray } );
function compareArray(other) {
  if (!other || other.length != this.length) return false;
  for (var i=0; i<this.length; i++) if (this[i] !== other[i]) return false;
  return true;
}

var a1 = [1, 2, 3, 4];
var a2 = [1, 2, 3, 4];
var a3 = [1, 2, 5, 6];
var a4 = [1, 2];

console.log(' a1 == a2 : ' + a1.compare(a2));
console.log(' a1 == a3 : ' + a1.compare(a3));
console.log(' a1 == a4 : ' + a1.compare(a4));

like below fixes the issue I found the solution, that (after all) is pretty obvious. Below you can see the final solution.
The key is the Database.SetInitializer that configure EF to initialize the database using the registered IDatabaseInitializers.
code :
[SetUp]
public virtual void SetupInitialData()
{
    var data = InitializeData();
    Context = new FmsDbContext();

    if (data != null)
    {
        Database.SetInitializer(new TestDataInitializer(data));
    }

    Context.Database.Initialize(true);
}

it helps some times The failing tests share a resource that affects them all when tested together. Recheck the affected tests and their subjects.
You should also look into static fields or properties in the subjects. They tends to cause issues if not used properly when designing your classes.
