How to erase contents in store() after each test?

[njoshi023]

Hi guys,

I am having an issue emptying out the store across my tests. This causes errors when I define models with the same id across multiple tests. Here is a really simply JSbin to illustrate - http://jsbin.com/qiwev/4/edit

  /*=================== APP ====================*/
Ember.MODEL_FACTORY_INJECTIONS = false;
App = Ember.Application.create();

App.Foo = DS.Model.extend({
});



/*=================== TESTS ====================*/

emq.globalize();
App.setupForTesting();
App.injectTestHelpers();
setResolver(Ember.DefaultResolver.create({ namespace: App }));
App.rootElement = '#ember-testing';


moduleForModel('foo', 'Foo model', {
  teardown: function() {
    // this.store().unloadAll('foo');
  }
});

test('Test 1', function() {
  var store = this.store();

  var model = this.subject({
    id: 1
  });

  ok(true);

});

test('Test 2', function() {
  var store = this.store();

  var model = this.subject({
    id: 1
  });

  ok(true);
});

test('Test 3', function() {
  var store = this.store();

  var model = this.subject({
    id: 1
  });

  ok(true);
});

The error I get is:

Error: Assertion Failed: The id 1 has already been used with another record of type App.Foo.

The commented out this.store().unloadAll('foo'); on teardown doesn't help either. So any suggestions on how I can reset the store across each test? Should that possibly be the default case as well to keep all tests independent? Thanks

We've also had issues with what I call the lifecycle of tests in ember and run across similar issues to this.
Seems to me that there are 2 solutions, neither of which are completely satisfactory:

1. use more randomised data. Maybe use faker.js or https://github.com/danielspaniel/ember-data-factory-guy
2. Move each test into their own moduleForModel e.g.

App.Foo = DS.Model.extend({
});


moduleForModel('foo', 'Foo model 1', {
  teardown: function() {
  }
});

test('Test 1', function() {
  var store = this.store();

  var model = this.subject({
    id: 1
  });

  ok(model);

});

moduleForModel('foo', 'Foo model 2', {
  teardown: function() {
  }
});

test('Test 2', function() {
  var store = this.store();

  var model = this.subject({
    id: 1
  });

  ok(model);
});

I made a helper function:

// tests/helpers/store.js

import Ember from 'ember';

const {
  run
} = Ember;

function waitForStore(assert, timeout=50) {
  const done = assert.async();

  run.later(this, function() {
    done();
  }, timeout);
}

export {
  waitForStore
};

my tests look like that:

import Ember from 'ember';
import { test, moduleForModel } from 'ember-qunit';
import { waitForStore } from '../../helpers/store';

const {
  run
} = Ember;

moduleForModel('project', 'Project', {
  needs: ['model:task']
});

test('it creates a simple project', function(assert) {
  expect(1);

  const store = this.store();

  run(this, function() {
    let project = store.createRecord('project', {
      name: 'Simple project'
    });

    assert.equal(project.get('name'), 'Simple project');
    assert.equal(project.get('tasks.length'), 0);
  });

  // extend the timeout waitForStore(assert, 100);
  waitForStore(assert);
});

@fsmanuel Could you expand a little on what waitForStore actually does? It appears as if you're using waitForStore() to call the async callback after a specified period. And this should give anything in teardown enough time to run? I'm still having trouble getting properties of my object to properly clear out after running Ember.run App, App.destroy
