Checking for Broken Links

Applies to TestComplete 14.71, last modified on April 22, 2021

TestComplete provides scripting access to web page elements as well as to their attributes, methods and events. So, you can do more than just perform functional testing of a web page. With TestComplete, you can check different characteristics of a web page and its elements. This lets you easily check the page elements and determine whether the web page matches the quality standards adopted in your organization.

It is obvious that you want to make sure that your tested web page does not contain broken links. To perform a check for broken links, you can either use a web accessibility checkpoint, or write script code. By writing script code you can create a more specific checking procedure (for instance, you can verify only specific links). However, using a checkpoint you can quickly and easily perform typical checks.

You can perform a check both from scripts and from keyword tests.

Checking for Mailto Links from Scripts

To perform checking from a script, you can write special script code or use the Web Accessibility Checkpoint dialog.

Using the Web Accessibility Checkpoint Dialog

You can create a web accessibility checkpoint during test recording or at design time:

  • To create a checkpoint during the test recording, click Add Check on the Recording toolbar. Click Web page in the resulting Checkpoint wizard and then click Verify web page contents.

  • To create a new checkpoint at design time, on the Code Editor toolbar, click Add Checkpoint via Wizard and then click Web page.

In the wizard:

  • Select the web page you want to check and click Accessibility.

  • To specify that TestComplete should check for broken links, select the Check link accessibility check box.

  • Press OK. TestComplete will generate and display the code that you can then insert into your script units.

Note that instead of creating a new checkpoint, you can also modify the Check link accessibility property of an existing Web Accessibility project element and then use this element to perform the check.

For more information on creating and using web accessibility checkpoints, see Web Accessibility Checkpoints.

Using Script Code

The code snippet below checks the accessibility of all A elements on the tested web page.

The Test routine uses the contentDocument.links property to obtain the collection of all A elements. The VerifyWebObject routine uses the aqHTTP.CreateGetRequest method to create a request object, and the aqHttpRequest.Send method to send a request to a server and get a response. It uses the aqHttpResponse.StatusCode property to check whether the request was successful.

JavaScript

function Test()
{

  URL = "https://www.smartbear.com"
  Browsers.Item(btIExplorer).Run(URL);
  let page = Sys.Browser("*").Page("*");

  let expectedObjectData = "";

  // Obtains the links
  let links = page.contentDocument.links;
  let linksCount = links.length;

  if (linksCount > 0)
  {
    // Searches for broken links
    for (let i = 0; i < linksCount; i++)
    {
      let link = links.item(i);
      let URL = link.href;
      Log.AppendFolder(URL);
      Log.Message("The " + URL + " verification results: " + VerifyWebObject(URL, expectedObjectData));
      Log.PopLogFolder();
    }
  }

}


// Checks whether the specified URL is valid
function VerifyWebObject(link, expectedObjectData)
{
  let httpObj = aqHttp.CreateGetRequest(link);
  try
  {
    let httpObjResult = httpObj.Send();
    if (httpObjResult != null)
    {
      switch (httpObjResult.StatusCode)
      {
        case 200:
        case 302:

        if (httpObjResult.Text != expectedObjectData)
        {
          Log.Message("The " + link + " link is valid", httpObjResult.Text);
          return false;
        }

      break;
      default:
        Log.Message("The " + link + " link was not found, the returned status: " + httpObjResult.StatusCode, httpObjResult.Text);
        return false;

      }
      return true;
    }

  }
  catch(e)
  {
    Log.Warning(e.message);
    return false;

  }
}

Checking for Mailto Links from Keyword Tests

To search for broken links on a web page from keyword tests, you can use the Web Accessibility Checkpoint operation or call the script routine described in the previous section.

To add the Web Accessibility Checkpoint operation to your keyword test, drag the operation from the Operations list to the test area in the Keyword Test editor. In the ensuing Checkpoint dialog, specify the tested web page, the name of the Web Accessibility project element that will be used for the verification and in the Options list select the Check link accessibility check box.

To call the described script routine from a keyword test, use the Run Script Routine operation. Prepare the script code and then append the operation to the test. TestComplete will display the Select Test dialog where you will be able to choose this script routine.
