Cucumber - Undefined Steps Though defined

Question

I'm creating a Simple Selenium Cucumber project and defined steps using "Lambda Expressions Constructor" way for a feature file but when I ran the CucumberTest class I'm getting failure exception as

There are undefined steps!

My StepDefinition is below one

And Feature file is the below one

CucumberRunner class is below:

So please suggest me is there any different approach for calling Step Definition File if I use Lambda Expressions?

Answer 1

As already mentioned in my comment. The option glue expects a list of package names, not directories. Changing it from

glue = {"src/test/java/my.project.automation.wolfram_alpha" }

to

glue = {"my.project.automation.wolfram_alpha" }

will solve the issue.

Find working snippets below. Assuming following structure

src/test/java/my/project/automation/wolfram_alpha/StepDef.java
src/test/java/my/project/automation/wolfram_alpha/cucumberTest.java
src/test/resources/wolfram.feature
pom.xml

StepDef.java

package my.project.automation.wolfram_alpha;

import cucumber.api.java8.En;

public class StepDef implements En {
    public StepDef() {
        Given("URL of WolframAlpha" , () -> {
            System.out.println("Given URL of WolframAlpha");
        });
        When("user logged in as {string} with {string}" , (String user, String password) -> {
            System.out.printf("When user logged in as {%s} with {%s}%n", user, password);
        });
        And("login is successful" , () -> {
            System.out.println("And login is successful");
        });
        And("user search for a {string}" , (String topic) -> {
            System.out.printf("And user search for a {%s}%n", topic);
        });
        Then("results are displayed in a creative way" , () -> {
            System.out.println("Then results are displayed in a creative way");
        });
    }
}

wolfram.feature from the question

Running the test with mvn test produces following output.

Running my.project.automation.wolfram_alpha.cucumberTest
Configuring TestNG with: org.apache.maven.surefire.testng.conf.TestNG652Configurator@726f3b58
Given URL of WolframAlpha
When user logged in as {user} with {password}
And login is successful
And user search for a {IDOL}
Then results are displayed in a creative way
