In this chapter, we have learned about various concepts and examples. The knowledge of DOM, JavaScript, and XPath is very handy for creating scripts. The XPath and DOM are the least used concepts in the QTP for script creation and validation, but these are helpful in creating manual checkpoints by retrieving the data from the web pages conveniently. Path is a really good way to navigate your site when there are no IDs on elements that you need to work with or near the element you want to work with. The next chapter talks about capturing and sharing the lessons learned during the test automation framework designing, and implementing them for future reference.
