![]() ![]() XPath certainly can be used to identify elements of an HTML web UI in Tosca. Since the question was originally posted, the "Forgot Password?" link at appears to have changed so that it's text is now "Forgot your password?" and is actually located at. It seems that XPath expressions need to be wrapped in double quotes (") so that XScan knows when to start evaluating XPath instead of using its normal rules.Some things to keep in mind when using XPath in Tosca: With the text modification, the expression works to idenfity the element in XScan after wrapping it in double quotes: "(//*)" To account for that change, this answer uses "(//*)" instead of the expression provided in the original post. Looking closely at the expression that is pregenerated when XScan starts, we see that it is wrapped in double quotes:Ī valid XPath expression doesn't necessarily guarantee uniqueness, so it is helpful to pay attention to any feedback messages at the bottom of XScan. There is a significant difference between "The selected element was not found" and "The selected element is not unique". The former simply indicates XScan can't find a match, the latter indicates that XScan matches successfully, but cannot uniquely identify the element. In this measure, you can choose to throw a custom exception, only to. Explicitly check for null from method calls and throw a custom exception. In order to avoid object reference not set to an instance of an object, you can choose to check for the null and provide a default value. My experience has been that it helps to explicitly identify the element to reduce the possibility of ambiguity. Explicitly check for null and provide a default value. If the idea is to target the anchor element in order for tests to click a link, then reducing scope from any element i.e. "(//*)" to only match anchor elements with that text "//a". In general, Tricentis (or at least the trainers with whom I have spoken) recommends using methods other than XPath to identify a target if they are available. An XPath expression is visible and editable in the XModuleAttribute properties without having to rescan.That said, in my experience I've had better luck with XPath than with "Identify by Anchor". If you do not want Tosca XScan to create screenshots, change Settings ->TBox ->Recorder ->Attach screenshot to modules to False.With Anchor, I've had issues where XModuleAttributes scanned in one browser can no longer be found when switching to another browser, specifically from IE to Chrome.Personally, I find it easier to work with than the XML value of the RelativeId property that is generated when using Identify by Anchor. ![]() If you run very large tests, these screenshots can take up a substantial amount of disk space. Identify controls by image: Image-Based Test Automationīy default, Tosca XScan attaches a screenshot to each Module that it creates.

Alternatively, use the keyboard shortcut Ctrl + Shift + A.or further information, see chapter Scan Modules. If controls cannot be uniquely identified by their controls, there are additional ways to identify them. Tosca XScan identifies controls based on their attributes, the default identification method. Tosca XScan automatically selects an engine to scan the application. Tosca XScan: To assist you in identifying controls in your test application, Tosca XScan provides various identification options.
