Match Patterns: You can use regular expressions to match specific patterns or text within your application's elements, such as web page titles, object properties, or text on a webpage. For example, you want to verify if a web page title starts with "Welcome to" followed by any text. You can use a regular expression as
^Welcome to.*.Dynamic Object Identification: Regular expressions can be helpful when the properties of web elements or objects are dynamic or change based on the content. By using regex, you can create more flexible and robust automation scripts. Suppose you 're are automating a web application, and the ID attribute of a button changes dynamically, but it always starts with
btn_submit. You can use a regular expression to identify this button as^btn_submit.*.Parameterization: You can use regular expressions to parameterize test data. This means you can use one test script for multiple test scenarios by defining the data pattern with regex. For example, if you have a set of email addresses, and you want to match any valid email address, you can use a regex like this:
^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}. This regex matches a wide range of valid email addresses.
Using Key Names in Parameterization
If you have a key TitleKey storing the value MyBrowser, you can use the Property Value for the Browser's title as {TitleKey}.
