    • DOM
    • link textual content
    • PartialLinkText
    • Xpath
    • CSS Selector
  14. What’s XPath?

    XPath is used to find net components primarily based on their XML (Extensible Markup Language) paths. It may also be used to find HTML components.

  15. What’s the distinction between single slash (/) and a double slash (//) in Xpath?

    Single slash (/) is used to create Xpath with an absolute path. On this case, the Xpath begins choice from the doc begin node.
    Double slash (//) is used to create Xpath with a relative path. On this case, the Xpath begins choice from anyplace inside the doc.

  16. What’s an Object Repository? How is it created in Selenium?

    An object repository permits a tester to retailer net components of the Utility Below Check (AUT) along with their locator values, in a number of centralized places versus hard-coding them inside the check scripts.

  17. How are you going to deal with home windows primarily based popups with Selenium?

    Selenium solely helps net software testing. It doesn’t help the testing of Home windows-based purposes. To deal with Home windows-based pop-ups, third social gathering intervention is required.
