我有一个基类，它将启动webdriver。以下页面可用于创建合同。

登录->选择计划->添加场所->添加详细信息

    public class BaseClass {
    public WebDriver driver;
    public WebDriverWait wait;

    public WebDriver getDriver() {
        return driver;
    }

    @BeforeClass(description = "Class Level Setup!")
    public void setup() {
        // Create a Chrome driver. All test classes use this.
        System.setProperty("webdriver.chrome.driver", "/Selenium/chromedriver");
        driver = new ChromeDriver();

        // Create a wait. All test classes use this.
        wait = new WebDriverWait(driver, 15);

        // Maximize Window
        driver.manage().window().maximize();
    }

}

然后登录。测试

    public class LoginTest extends BaseClass {

 @Test(priority = 0, description="This TC is for Senoko login")
  void validateLogin() {
      driver.get("https://url domain/index"); 

      WebElement email = driver.findElement(By.id("userid_txt"));   
      WebElement password = driver.findElement(By.id("password_txt"));
      WebElement login = driver.findElement(By.id("submitBtn"));
      email.sendKeys("a01");
      password.sendKeys("test123");
      login.click();
      HouseholdCheck house=new HouseholdCheck();
      house.houseCheck();
  } 

}

到此为止，一切正常。在validateLogin()方法中，调用houseCheck方法，在这里我得到NullPointerException。

  public class HouseholdCheck extends BaseClass {

@Test
void houseCheck() {
    System.out.println("=====" + driver);
    driver.get("https://a-sit.aspx?source=CSP&key=1");
    WebElement radio1 = driver.findElement(By.xpath("//input[@name='resbiz' and @value='households']"));
    WebElement radio2 = driver.findElement(By.xpath("//input[@name='resbiz' and @value='business']"));
    radio1.click();
    WebElement radbutton = driver.findElement(By.xpath("//button[contains(.,'Continue')]"));
    radbutton.click();
    PlanSelect plnslct = new PlanSelect();
    plnslct.planSelect(driver);
}

}

在HouseholdCheck类中，无法访问driver。提供NullPointerException。请指导我，如何将驱动程序传递给后续课程？如果某个类扩展了BaseClass，为什么该类无法获得驱动程序对象？

Answer 1

在HouseholdCheck house = new HouseholdCheck();中创建BaseClass的新实例，其中从未初始化driver。您将houseCheck()作为方法调用，而不将其作为测试运行，因此setup()未被执行。

一种解决方案是将driver设为静态

private static WebDriver driver;

public static WebDriver getDriver() {
    return driver;
}

Answer 2

public class BaseClass {
    public static WebDriver driver;

只需将此设置为静态，就可以了。
