In the WebPollId field, select the poll that you have just created. Now open the Web Sites form from the main application menu path Administration Setup Internet Web Sites and go to the Setup tab. Click on the pencil icon to the right of the Web Application field. This displays the project structure in the Project Manager window. Find the Web Pages folder at the root and expand it and the Standard subfolder. Select the page where you want to include the poll for now, select the EP home page, entitled EPHomePageOnline. Double-click on the icon that represents the node, or right-click and select the Edit menu option. This opens the page in the Web application editor where you can define the content and layout of the page in question. It will resemble Figure 16-10, but without the poll Weblet and menu. Now select the Insert Navision Axapta Element Weblet menu option. It opens the Weblets form, from which you can select the Weblet to add select the Online Poll Weblet and double-click on it or press the OK button on the form. A large rectangular bitmap representing the Weblet is placed wherever your cursor is positioned on the Web application. This automatically displays the properties form for the Weblet (see Figure 16-9), where you have to select your poll in the WebPollId field. Then drag your poll to a position where it looks relatively attractive below the Error Handler Weblet, for example.

Figure 6 6. Test scenarios for the Dates are correct controller As you can see in Figure 6 6, we ve replaced the Default Run scenario with four of our own scenarios. Each one represents a particular check that we ll want the code to perform, in order to validate that the dates are correct. You may be wondering about the tabs running along the bottom of the screen in Figure 6 6: Unit, Integration, System, Acceptance, and Scenario. We ve put the controller test scenarios on the Unit tab, as controller tests essentially are just big ol unit tests. When it comes to writing the code for them and running them, most of the same rules apply (except for the white box/gray box stuff, which we ll discuss elsewhere in this chapter).

Methods such as getElementById and getElementsByTagName are extremely useful for retrieving information about the structure and content of a document. The DOM is a representation of the document. The information contained in the DOM reflects the information in the document. Once you know how to ask the right questions (using the right methods), you can get the details of any node in the DOM. The DOM is a two-way street. You can query the contents of a document and you can also update the contents of a document. If you change the DOM tree, you will change the document as viewed in a browser. You ve already seen this voodoo in action with setAttribute. Using that method, you can alter an attribute node in the DOM. This change is reflected in the document displayed in the browser. You haven t physically changed the document. If you open the document in a text editor instead of a browser, you won t see a changed attribute. The changes to the document can be seen only when a browser renders the document. This is because the browser is really displaying the DOM tree. As far as the browser is concerned, the DOM tree is the document. Once you understand this, the idea of creating markup on the fly isn t quite so strange. You aren t really creating markup, you re updating the DOM. The key to doing this is to think in the same terms as the DOM. According to the DOM, a document is a tree of nodes. If you want to add to this tree, you need to insert new nodes. If you want to add markup to a document, you need to insert element nodes.

Note When you insert a Weblet, it s a good idea to place the cursor where you want to display the results

If you look at Figure 6 6, each test scenario has its own Description, Input, and Acceptance Criteria fields. These define the inputs and the expected valid outputs (acceptance criteria) that we ve been banging on about in this chapter. It s worth spending a little time filling in these details, as they are really the crux of each test scenario. In fact, the time spent doing this will pay back by the bucket-load later. When EA generates the test classes, the notes that you enter into the Description, Input, and Acceptance Criteria fields will be copied right into the test code as comments, making the perfect test recipe from which to implement the tests.

at runtime, or it will be placed at the top automatically, and it s not easy to reposition it afterward.

The test.html file should contain an empty <div> with the id value of "testdiv": <div id="testdiv"> </div> Now suppose you want to insert a paragraph into "testdiv". To use the language of the DOM, you want to add a p element node as a child node of the div element node (which already has one child node: an id attribute node with the value "testdiv"). This is a two-step process: Create the new element. Insert the element into the node tree.

Note The Web application editor is not totally WYSIWYG when it comes to Weblets, so the page may look
