An example of unified code to reuse the same functional test scenario. Gherkin is the language that Cucumber uses to define test cases (test scenarios). In Cucumber, step definitions should be stored in a named package under Test Sources Root. An annotation followed by the pattern is used to link the Step Definition to all the matching Steps , and the code is what Cucumber will execute when it sees a Gherkin Step . So, currently I am defining N number of feature files (separate feature file for each scenario), and same number of java packages. One workaround is - Keeping definitions in the default package might result in an error as IntelliJ IDEA will not be able to locate them.

Step 7 − Add dependency for Cucumber-Java − This will indicate Maven, which Cucumber files are to be downloaded from the central repository to the local repository. But usually we have some steps that we want to re-use. Over unit tests of the core component code, or exposed API and services, and finally the web application UI. Let us assume that we simply copy the missing step into the SubtractStepdefs.java file, we now have duplicate step definitions according to Cucumber, which is ofcourse correct if we think that each step is in essence globally scoped by Cucumber.
