使用 Cucumber JVM 运行测试时出现 UndefinedStepException

Question

I develop a test for the mobile application using Cucumber+Junit+Appium. When I try to run a test using cucumber and JUnit runner I receive: io.cucumber.junit.UndefinedStepException: The step "I install the application" is undefined. You can implement it using the snippet(s) below: io.cucumber.junit.UndefinedStepException: The step "I install the application" is undefined. You can implement it using the snippet(s) below:

I tried some of the solutions from the medium blog and stack question, but this doesn't help.

I have a project structure:

src
 |-main
 |--java
 |---{project-name}
 |----config
 |----models
 |----screens
 |----services
 |-test
 |--java
 |---{project-name}
 |----helpers
 |----stepDefinitions
 |-----LoginStep.java
 |-----BaseStep.java
 |-----LoginStep.java
 |----RunCucumber.java
 |--resources
 |---feature
 |----Login.feature 

RunCucumber.java

package com.mobile.automation.framework;

import com.google.inject.Guice;
import com.mobile.automation.framework.module.ServiceModules;
import com.mobile.automation.framework.service.AppiumServer;

@RunWith(Cucumber.class)
@CucumberOptions(
        strict = true,
        monochrome = true,
        glue = "src.test.java.com.mobile.automation.framework.stepDefinition",
        features = "src/test/resources/feature",
        plugin = {"pretty", "html:target/cucumber-report/cucumber.html",

        driver = new DriverFactory().getDriver();
    }

    @After
    public void tearDownDriver() {
        if (driver != null) {
            driver.quit();
            new AppiumServer().stopServer();

    }

    private void init() {
        Guice.createInjector(

    }
}

Login.feature

Feature: Sign In feature

  Background:
    Given I install application
    And I enable all network activity
    Then I am on Sign Page

  Scenario: Sign In scenario
    Given I am go to the Login Page
    And I fill valid user data using "Config"
    And I click sign in button

    Then I am login in the application

LoginStep.java

package com.mobile.automation.framework.stepDefinition;

import javax.inject.Inject;

import com.mobile.automation.framework.config.ProjectConfig;
import com.mobile.automation.framework.models.User;
import com.mobile.automation.framework.screens.DashboardScreen;
import com.mobile.automation.framework.screens.SignInScreen;
import io.cucumber.java.ParameterType;
import io.cucumber.java.en.And;
import io.cucumber.java.en.Given;
import io.cucumber.java.en.Then;

import static org.assertj.core.api.AssertionsForClassTypes.assertThat;

/**
 * @author Tomash Gombosh
 */
public class LoginStep {
    @Inject
    private SignInScreen signInScreen;
    @Inject
    private DashboardScreen dashboardScreen;

    @Given("^I am go to the Login Page$")
    public void iAmGoToTheLoginPage() {
        dashboardScreen.tapLogin();
    }

    @And("I fill valid user data using {string} {string}")
    public void iFillValidUserDataUsing(String userName, String password) {
        signInScreen.fillLogin(userName, password);
    }

    @And("I fill valid user data using {string}")
    @ParameterType("Config")
    public void iFillValidUserDataUsing() {
        signInScreen.fillLogin(new User(data -> {
            data.setEmail(new ProjectConfig().getBaseUser());
            data.setPassword(new ProjectConfig().getBaseUserPassword());
        }));
    }

    @And("I click sign in button")
    public void iClickSignInButton() {
        signInScreen.clickLogin();
    }

    @Then("I am login in the application")
    public void iAmLoginInTheApplication() {
        assertThat(signInScreen.isDisplayed()).isEqualTo(true);
    }

}

Some of the steps on the Login class is missing, but that is because I want to put all the code to the question.

I expected to run that feature, but actually that is not work.

Answer 1

Typically src.test.java is not part of the package name. Try using:

glue = "com.mobile.automation.framework.stepDefinition",

And because Cucumber will search the runners package for glue by default can also remove the glue entirely.

Answer 2

New here myself working on Junit Runner, I agree with @MPKorstanje with classpath. Although I just had to change glue to refer the stepDefs with classpath too - wasn't getting recognized before.

So basically this is what I did to catch the necessary files to be triggered

feature = { "classpath:path-from-repo-root.feature" },
glue = { "classpath:reference-to-stepDef-folder" }

Bear in mind: for glue - I used to the reference to the folder containing the stepDefs and not the stepDef file itself. Hope this helps someone. Thanks
