Test Driven Ajax (on Rails)

Wiki Tests Wiki

Add reveal() to that test case, run the test batch, wait for a web browser to pop up, and click on a test button. The target IFRAME should display, with a familiar "missing web page" error. The IFRAME can't navigate to a bogus src URI.

Until now, our YAML has been fictitious. We need to create a new Wiki page, to test our own Wiki.

  def set_wiki_test_up
    source = "--- !omap
      - setup:
        - !omap
          - script: \"\"
      - test_WikiTestPage:
        - !omap
          - color: green
          - page: /wiki/WikiTestPage
          - script: something tests our Wiki
      - teardown:
        - !omap
          - script: \"\"
      "
    @yar = YarWiki.new('TestWiki')
    @yar.save_page(source)
  end

  def self_test
    set_wiki_test_up
    get :index, :id => @yar.page_name

    assert_select 'td#wiki_panel' do |wiki_panel|
      return wiki_panel
    end
  end

  def test_surf_self
    wiki_panel = self_test
    reveal()
  end

The new page, TestWiki, will soon have commands that test our sample page, WikiTestPage. Then we will use those commands to test-first features into our Wiki.

But for now, all we can do is reveal() this new page, click the test button, and drop our jaws:

Figure 6. Our Wiki opens a panel now, revealing our Wiki.

The inner Wiki is fully functional, so if it had any more features, we could click on them, and manually test them.

Now gaze at that script node. All it says is "something tests our Wiki". We need to do better than that if we actually want to test it!
