@oliverbarnes see the mocha docs on using before, beforeEach etc. at http://mochajs.org

describe('hooks', function() {

  before(function() {
    // runs before all tests in this block
  });

  after(function() {
    // runs after all tests in this block
  });

  beforeEach(function() {
    // runs before each test in this block
  });

  afterEach(function() {
    // runs after each test in this block
  });

  // test cases
});

Also do you know if the ember-mocha provides this.container ?

I don't, looking into it. about beforeEach, you mean they should be within the describe('#toggleSupport', function() { block rather than the describeModule?

@oliverbarnes yeah the way I have the beforeEach in the EJR blueprint is specifically for the Ember-QUnit test module setup and teardown. So with Mocha that is done differently, more BDD like syntax.
