Question

我正在尝试加载一个菜单，但是得到了这个错误：

Preview

功能文件：

Preview

代码如下：

Step Definition (Failing @When step):
public class ThresholdsAndAlertsPageSteps {
    
    private LoginPage loginPage = new LoginPage(DriverFactory.getDriver());
    private DashboardPage dashboardPage;
    private ThresholdsAndAlertsPage thralertPage;
    
    @When("user clicks on ThresholdsAndAlerts link")
    public void user_clicks_on_thresholds_alerts_link() {
        dashboardPage.clickMenu();
        thralertPage = dashboardPage.clickMenu();
    }

    @Then("user gets the title of the page menu {string}")
    public void user_gets_the_title_of_the_page_menu(String expectedTitle) {
        String actualTitle = thralertPage.getPageMenu();
        Assert.assertTrue(actualTitle.contains(expectedTitle));
        System.out.println(actualTitle);
    }
}

页面：

package com.pages;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;

public class ThresholdsAndAlertsPage {
    
    private WebDriver driver;
    
    //1. Locators

    private By menu_title = By.xpath("//div/div[2]/div[2]/div/div/div/h3/span");
    
    //2. Constructor
    public ThresholdsAndAlertsPage(WebDriver driver) {
        this.driver = driver;
    }
    
    //3. Page Actions   
    public String getPageMenu() {
        return menu_title.toString();
    }
    
    public ThresholdsAndAlertsPage navigateThresholdsAndAlertsPage() {
        return new ThresholdsAndAlertsPage(driver);
    }
    
    public void clickDefineThresh() {
        driver.findElement(dfn_thrs).click();
    }
    
}

会永远感谢你的帮助！

未初始化DashboardPage和ThresholdsAndAlertsPage类。而且你还得超过司机。

Step Definition (Failing @When step):
public class ThresholdsAndAlertsPageSteps {
    
    private LoginPage loginPage = new LoginPage(DriverFactory.getDriver());
    private DashboardPage dashboardPage;
    private ThresholdsAndAlertsPage thralertPage;
    
    @When("user clicks on ThresholdsAndAlerts link")
    public void user_clicks_on_thresholds_alerts_link() {
        dashboardPage = new DashboardPage(DriverFactory.getDriver());
        dashboardPage.clickMenu();
        thralertPage = new ThresholdsAndAlertsPage(DriverFactory.getDriver());
        thralertPage = dashboardPage.clickMenu();
    }

    @Then("user gets the title of the page menu {string}")
    public void user_gets_the_title_of_the_page_menu(String expectedTitle) {
        String actualTitle = thralertPage.getPageMenu();
        Assert.assertTrue(actualTitle.contains(expectedTitle));
        System.out.println(actualTitle);
    }
}
