We consider the following before building a Selenium Cucumber automation application:- Determine the type of application you'll be testing. Is it a Web app, a mobile app, or a desktop application? Is there a need for backend testing? Databases or SDKs, for example. Is it necessary to run the app through an internationalization test? It must include a report that allows you to track down a problem with minimal effort. It must be able to generate parametrization tests automatically. Any setup-related settings or global attributes should be defined in a config file. To segregate the functionality, use abstraction at every level.
