Add screenshots in XML and HTML reports

[Galad]

Screenshots should be added in the XML and the HTML reports.
For that, we need to extend the current XmlReportingObserver in order to add custom value in the current action (because the ScreenshotInfo class is in the Tranquire.Selenium project).

We can make XmlReportObserver implement the interface IObservable<ActionAttachment> in order to add the ability to add attachment to the each action or question.
Then we can create an adapter to transform the result of IObserver<ScreenshotInfo> into ActionAttachment.

The composition will look like this:

var xmlDocumentReporting = new XmlDocumentObserver();
var directory = Path.Combine(GetTestDirectory(), "Screenshots");
_observer = new SaveScreenshotsToFileOnComplete(directory);
var screenshotObserver = new CompositeObserver<ScreenshotInfo>(
                                              _observer,
                                              new ScreenshotInfoToActionAttachmentObserver(
                                                  directory,
                                                  xmlDocumentReporting
                                              )
                                          );
var actor = new Actor("John")
               .WithReporting(xmlDocumentReporting)
               .TakeScreenshots(screenshotName, screenshotObserver)

Steps:

• Implement IObservable<ActionAttachment> in XmlDocumentObserver in order to add attachments. in the XML document. Attachments should be a single element attachments containing 0 or many attachment elements. It should have the properties:
  • filepath
  • description
• Create ScreenshotInfoToActionAttachmentObserver
• Render screenshots in the HTML report
• Create CompositeObserver<T>
