Identify by index So, it will be a nice idea to keep them like defaults. Related. Wrapping Selenium calls is one of the Selenium best practices that can significantly impact maintaining a complex test suite (or test code). In my humble opinion all the other examples that are using try-catch to see if an element exist are bad programming style. XPath is more brittle as reordering elements in a page or introducing a new web element can cause the existing implementation with XPath to fail. With LambdaTest, you can perform automated testing with Selenium for 3000+ browser and operating systems. Avoiding duplication also helps in the reduction of code size and improves the maintainability of the test code. These two headers are the only settings that truly matters.
