While the notion of use case object might seem very simple on the first sight, implementing them properly takes quite a bit of skill in practice. Therefore, in this post, I’ll describe how to design proper use
Before demonstrating how to write test cases in Java, let’s learn how different WebElements used in the test flow can be located using their locator strategies. We will use XPath or ID locators to locate all the WebElements for this test case. You can use one of the most common methods...

In this section, you will create your first programming loop in Java using thewhilekeyword. You’ll use a singleintvariable to control the loop. Theintvariable will be calledxand will have an initial value of3. While, or as long as,xis bigger than0, the loop will continue executing a...
Java Copy In this example, we useArrays.sort()to sort an array of integers. The output shows the array sorted in ascending order. How to Sort a List in Java WithStream.sorted() Features in Java 8included the Stream API, which provides asorted()method that returns a stream consisting of...

The Adapter design pattern in Java , also known as the Wrapper pattern, is another very useful GOF pattern that helps bridge the gap between two classes in Java. According to the Gang of Four pattern list, Adapter is a structural pattern, m
