Question

我正在尝试使用Cucumber的功能文件运行自动化测试。运行功能文件后，我得到：

cucumber.runtime.CucumberException: Failed to instantiate class stepdefs.DashboardWidgets.PMovers
at cucumber.fallback.runtime.java.DefaultJavaObjectFactory.cacheNewInstance(DefaultJavaObjectFactory.java:45)

我有一个由另一个实习生制作的帮助程序文件，其中包括诸如在其构造函数中初始化实际ChromDriver的帮助程序方法。奇怪的是，所有这些测试都是在一个月前进行的，但是当我切换回该分支时，却遇到了很多奇怪的问题。

我尝试更新chromedriver版本，开始一个新项目，进行全新整洁的重建，并查看我的依赖项。

这是我正在谈论的GeneralFactory帮助器类的摘要，当它到达this.driver = new ChromeDriver（）行时，将引发错误：

public class GeneralFactory {
    /*
    General factory class that contains functions used by all stepdefs
     */
    public ChromeDriver driver;

    public GeneralFactory() {
        this.driver = new ChromeDriver();
    }

    public void login_to_desktop() {
        //driver.manage().window().maximize();
        driver.get("https://develop.q4desktop.com/");
        LoginPage loginPage = new LoginPage(driver);
        loginPage.loginUserCloseWelcomeNote();
    }

这是我的实际功能文件：

Feature: PeerMovers Widget
  User can use the Peer Movers widget

  Background: User can add a Peer Movers widget
    Given the user can login to test Peer Movers
    Then the user can add a peer movers widget

  Scenario: User can see the peer movers page
   When the peer movers widget loads in
   Then the user can see the peer movers widget

如您所见，这是一些非常简单的内容，现在是与此功能文件相关联的实际Java文件片段：

 public GeneralFactory factory = new GeneralFactory();
    private String peerName;

    @Given("^the user can login to test Peer Movers$")
    public void login_() {
        factory.login_to_desktop();
    }

    @Then("^the user can add a peer movers widget$")
    public void addPeerAlertsWidget() {
        DashBoardWidgetPage dashBoardWidgetPage = new DashBoardWidgetPage(factory.getDriver());
        dashBoardWidgetPage.goToNewDashboardPage();
        dashBoardWidgetPage.addPeerMoverToDashboardPage();
    }

    @When("^the peer movers widget loads in$")
    public void peerMoversLoaded(){
        PeerMoversWidget peerMoversWidget = new PeerMoversWidget(factory.getDriver());
        peerMoversWidget.waitForElement(peerMoversWidget.getItemNames());
    }

    @Then("^the user can see the peer movers widget$")
    public void canSeePeerMovers(){
        PeerMoversWidget peerMoversWidget = new PeerMoversWidget(factory.getDriver());
        Assert.assertTrue("The user does not see the Peer Movers Widget", peerMoversWidget.
                getValues() != null);
    }

完整错误可以在这里看到：
