Hello everyone. I’m following the test on page 109, but it not works ☹  
When I ran this test, it breaks on line 10 (`assert_select 'h2', 'Programming Ruby 1.9'`

```auto
class StoreControllerTest < ActionDispatch::IntegrationTest
  test 'should get index' do
    get store_index_url
    assert_response :success
    assert_select 'nav a', minimum: 4
    assert_select 'main ul li', 3
    assert_select 'h2', 3
    assert_select 'h2', 'Programming Ruby 1.9'
    assert_select 'div', /\$[,\d]+\.\d\d/
  end
end

```

The error message:

```auto
# Running:

F

Failure:
StoreControllerTest#test_should_get_index [/home/grave/workspace/personal/learning/depot/test/controllers/store_controller_test.rb:10]:
Expected: "Programming Ruby 1.9"
  Actual: "MyString".
Expected 0 to be >= 1.

```

and my fixture:
