In the last post, we discussed hand coding web application in coded UI testing and also we faced problem while trying to identify controls of next page (which was User Form Page)
The problem was, every time while identifying a control from next page, we were needed to re-identify BrowserWindow and HtmlDocument as the parent of the control within the page, hence, the hierarchy for identifying any given control was this
Figure 1: Parent-Child Relationship
We can also view the same relation in UIMap.Uitest window, which looks something like this
Figure 2: UIMap.Uitest of Visual Studio
Why do we need relationship?
Before answering this question, let’s take our most popular browser automation testing tool Selenium.
Let’s examine the code snippet below
Figure 3: Selenium Code Snippet (JAVA)
The above code snippet leaves us with following questions
- Where is the relationship of controls maintained?
- How does Selenium manage to identify the controls?
As shown in the code snippet, we are first creating the instance for WebDriver and then using this instance, we are finding all the controls, thus, the in selenium the relationship for identify each and every controls are by default maintained using the instance of Web Driver.
Needless of where the browser takes the page, the web driver has the handle for every controls, hence there require no relationship.
