How To Write Test Cases in Java

Writing test cases in Java is a fundamental skill for ensuring the reliability and robustness of code. Test cases can help identify bugs and validate that the code works as intended. Java is one of the most used programming languages for automation testing, and writing test cases in Java involves building an entire automation project that follows OOP concepts. Automated test cases execute some flow on a webpage and then use assertions to verify if the output matches the desired output. To write effective test cases in Java, several things need to be considered, like the test flow, the test scope, naming, assertions, test data, grouping, locating WebElements, etc. TestNG is often used as a testing framework for handling test execution and implementing setup and teardown methods. To leverage all the features of cloud-based platforms like LambdaTest, some modifications need to be made in the code to use Selenium RemoteWebDriver, which helps connect to the cloud grid and execute cases over there.
