java - Cucumber Undefined Step, Though Defined Using IntelliJ

Question

I'm trying to run a .feature file to test a simple RESTEasy web application: https://github.com/dashorst/jaxrs-quickstart-resteasy.

However, the IntelliJ keeps saying that:

Undefined step: Given  I am an invalid username

Undefined step: When  I perform a hello request with null username

Undefined step: Then  I receive a http response code of 400

Undefined step: When  I perform a hello request with empty username

Undefined step: Then  I receive a http response code of 400

You can implement missing steps with the snippets below:

@Given("^I am an invalid username$")
public void I_am_an_invalid_username() throws Throwable {
    // Express the Regexp above with the code you wish you had
    throw new PendingException();
}
// similar results...

Below is my hello.feature file:

Feature: hello

#-------------------------------------
#next block is got the GET entry point
#-------------------------------------

#verify that with malformed input hello fails 
Scenario: invalid username should fail
Given I am an invalid username
When I perform a hello request with null username
Then I receive a http response code of 400
When I perform a hello request with empty username
Then I receive a http response code of 400

#verify that you can get correct hello response with valid username. This is the 'everything works fine' path.
Scenario: User can get correct hello response with valid username
Given I am a valid username
When I perform a hello request with valid username
Then I receive a http response code of 200

import cucumber.annotation.en.Given;
import cucumber.annotation.en.Then;
import cucumber.annotation.en.When;
import cucumber.runtime.PendingException;

I used IntelliJ option "generate steps" and got the MyStepdefs file.

/**
 * Created by z on 5/21/17.
 */
public class MyStepdefs {
    @Given("^I am a valid username$")
    public void iAmAValidUsername() throws Throwable {
        // Write code here that turns the phrase above into concrete actions
        throw new PendingException();
    }

    @Given("^I am an invalid username$")
    public void iAmAnInvalidUsername() throws Throwable {
        // Write code here that turns the phrase above into concrete actions
        throw new PendingException();
    }

    @When("^I perform a hello request with null username$")
    public void iPerformAHelloRequestWithNullUsername() throws Throwable {
        // Write code here that turns the phrase above into concrete actions
        throw new PendingException();
    }

    @Then("^I receive a http response code of (\d+)$")
    public void iReceiveAHttpResponseCodeOf(int arg0) throws Throwable {
        // Write code here that turns the phrase above into concrete actions
        throw new PendingException();
    }

    @When("^I perform a hello request with empty username$")
    public void iPerformAHelloRequestWithEmptyUsername() throws Throwable {
        // Write code here that turns the phrase above into concrete actions
        throw new PendingException();
    }

    @When("^I perform a hello request with valid username$")
    public void iPerformAHelloRequestWithValidUsername() throws Throwable {
        // Write code here that turns the phrase above into concrete actions
        throw new PendingException();
    }
}

I had tried to specify glue path for each scenario, but it doesn't work. I'm not sure what went run. Thanks for any advice!

I have looked into several existing questions but none of them helps:

Cucumber: undefined step, although step should be defined

Cucumber JVM undefined step

This is my project structure:

Answer 1

Sometimes it happens when there are saved references to the old names of the packages. If the packages have been renamed you should check if there are references to the old names (Cucumber Run/Debug Configurations) and delete them.

Kind regards
