Cucumber, Java8: find usage of step defined by lambda expression

Question

Currently in our project's tests we switched from using annotated step definitions, e.g.:

public class Steps {
    @Given("^Step name$")
    void methodName() { 
        // do sth
    }
}

to lambda expressions:

public class Steps implements En {
    public Steps() {
        Given("^Step name$", () -> 
            // do sth
        );
    }
}

When using Intellij Cucumber Java plugin it was easy to find the usage of some step, since it looked for usages of the annotated method (I presume). Now however, we have to manually search for the regex passed as the argument.

My first question is: is there a neat way to do this with lambda expressions?

Moreover: when using Intellij's tool for version control and commiting files containing definitions of big numbers of steps, the code analysis tool goes on forever (I guess it is because of the constructor having to crank a lot of code).

So the second question is: since there is no possibility of the step library shrinking and step usage search is used very often wouldn't it be a good idea to switch back to Ye Olde Way i.e. using annotated methods?

Answer 1

Find usages for java-8 style step definitions do not yet work. One can vote and follow this request: IDEA-144648.

Answer 2

It is working here while using

• IntelliJ IDEA 2018.1.5
• 'Cucumber for Java' plugin 181.5281.24

Feature: demo for java8 glue classes

  Scenario: user login on home page
    Given user is on home page
    When user navigate to login page
    And user enters credentials to login
    Then message displayed login successfully

glue/StepPojo.java

package glue;

import cucumber.api.PendingException;
import cucumber.api.java8.En;

public class StepPojo implements En {
    public StepPojo() {
        Given("^User is on Home Page$", () -> {
            throw new PendingException();
        });
        When("^User Navigate to LogIn Page$", () -> {
            // Write code here that turns the phrase above into concrete actions
            throw new PendingException();
        });
        And("^User enters Credentials to LogIn$", () -> {
            // Write code here that turns the phrase above into concrete actions
            throw new PendingException();
        });
        Then("^Message displayed Login Successfully$", () -> {
            // Write code here that turns the phrase above into concrete actions
            throw new PendingException();
        });
    }
}

The class StepPojo.java was created by the Cucumber plugin by pressing ALT+ENTER while selecting a step in the feature file.

The feature file was shown before as

after the steps are defined as

[

when you hover with the mouse over a step while pressing down the CTRL key it looks as

when you click on a step while pressing down the CTRL key you jump to the respective method, e.g.

Given("^User is on Home Page$", () -> {
    throw new PendingException();
});
