我使用Cucumber+Junit+Appium为移动的应用程序开发了一个测试。io.cucumber.junit.UndefinedStepException: The step "I install the application" is undefined. You can implement it using the snippet(s) below:
我尝试了一些来自中型博客和堆栈问题的解决方案，但这没有帮助。
我有一个项目结构：

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;

/**

 */
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);
    }

}

Login类上的一些步骤丢失了，但那是因为我想把所有的代码都放到这个问题上。
我希望运行该功能，但实际上这是行不通的。
