In Cucumber, each line of the Gherkin scenario maps to a method in a Java class, known as a 'Step Definition'. If the conversion would have been other way around, then you would have a list of Maps as Data table would have multiple rows (values for different maps) against the columns (keys). So our test should enter Username & Password once, click on LogIn button and repeat the same steps again.
