Similar to JUnit @Before and @After tagging a method with either of these will cause the method to run before or after each scenario runs.

Cucumber - Annotations - Annotation is a predefined text, which holds a specific meaning. @AfterConfiguration. @Before(order = int): This runs in increment order, means value 0 would run first and 1 would be after 0 It’s best to keep these feature files smaller, so that the Background information is more readily available. Similar to the above, since these steps won’t be listed with each scenario, the more vivid, the test step is, the easier time the user will have remembering it. Quit the web driver: This is most commonly used. Cucumber Hooks allows us to better manage the code workflow and helps us to reduce the code redundancy. And when you hit return is going to create.
