Ember Testing: Cannot read property 'createRecord' of null

It appears that store is not available in my Ember tests, whether in the context of an ObjectController or within any unit tests. My unit test:

`import {test, moduleFor} from "ember-qunit"`
`import DS from "ember-data"`

moduleFor "controller:register", "RegisterController", {
}

test "store is working", ->
    expect 1
    controller = @subject()
    Ember.run(->
        sampleUser = controller.get("store").createRecord("user", {
            username: "myuser"
            password: "otherpassword"
        })
        ok(sampleUser instanceof DS.Model)
    )

The test will give:

Died on test #1 at test (http://localhost:4200/assets/vendor.js:73539:13) at eval (app/tests/unit/controllers/register-test.js:19:5) at requireModule (http://localhost:4200/assets/vendor.js:54:29) at http://localhost:4200/assets/test-loader.js:14:29: Cannot read property 'createRecord' of null

Can anyone explain why I am not able to access DS capabilities from either within my tests or from within the controller itself (when running tests)?

Could you create an instance of the store manually -then inject that /add that to your controller (under test) to verify this works as you'd expect? - Toran Billups

Because ember-qunit doesn't inject the store into your controllers, it's meant for unit tests, not integration tests. And Ember Data's store is outside of the scope of that controller.

You can add the ember-data store to the "needs" section of the unit test. You will also need to add any models being created to the "needs" section like so:

needs: ['service:store', 'model:user']

This will inject a real instance of the store into the object (controller, component, route, etc.) being tested.
