Question

我遇到使用selenium运行Page Factory with maven的问题，如果有人可以帮助解决这个问题，我会很感激。当我运行TestPage类时，我得到以下错误：

org.testng.TestNGException: 
Cannot inject @Test annotated Method [SelectCourse] with [interface org.openqa.selenium.WebDriver].
For more information on native dependency injection please refer to http://testng.org/doc/documentation-main.html#native-dependency-injection

package pageObjectFactoryMaven;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.FindBy;
import org.openqa.selenium.support.PageFactory;

public class SelectCoursePage {

    WebDriver driver;
    public SelectCoursePage (WebDriver driver) {
        PageFactory.initElements(driver,this);
    }

    @FindBy (id = "navBlue")
    WebElement studying;

    @FindBy (css = "element")
    WebElement findacourse;

    @FindBy ( id = "query")
    WebElement entersearchitem;

    public WebElement studying(){
        return studying;
    }

    public WebElement findacourse(){
        return findacourse;
    }

    public WebElement entersearchitem(){
        return entersearchitem;
    }
}

package pageObjectFactoryMaven;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.FindBy;
import org.openqa.selenium.support.PageFactory;

public class SignInPage {

    WebDriver driver;

    public SignInPage (WebDriver driver) {
        PageFactory.initElements(driver, this);
    }

    @FindBy (id ="MUA_CODE")
    WebElement enterusername;

    @FindBy (id ="PASSWORD" )
    WebElement enterpassword;

    @FindBy (name = "OK.DUMMY.MENSYS.1")
    WebElement clickLogin;

    public WebElement enterusername() {
        return enterusername;   
    }

    public WebElement enterpassword() {
        return enterpassword;
    }

    public WebElement clickLogin() {
        return clickLogin;
    }
}

package TestClass;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.Test;

import pageObjectFactoryMaven.SelectCoursePage;
import pageObjectFactoryMaven.SignInPage;

public class TestPage {

    @BeforeMethod
    public void setup (){
        System.setProperty("webdriver.chrome.driver", "D:/Drivers/chromedriver.exe");
        WebDriver driver = new ChromeDriver();
        driver.get("wwww.hhg.com");
    }

    @Test
    public void SelectCourse (WebDriver driver) {
        SelectCoursePage POF1 = new SelectCoursePage (driver);
        POF1.studying().click();
        POF1.findacourse().click();
        POF1.entersearchitem().sendKeys("computer science");    
    }

    @Test
    public void SignIn (WebDriver driver) {
        SignInPage POF2 = new SignInPage (driver);
        POF2.enterusername().sendKeys("kff");
        POF2.enterpassword().sendKeys("jdnd");
        POF2.clickLogin().click();     
    }
}

Answer 1

问题在于您的测试代码。您的@Test方法签名表明它需要一个WebDriver对象作为参数，但您还没有告诉TestNG应如何查找实例然后将其注入@Test方法。 TestNG本身只能将以下参数作为参数注入您的@Test方法（这就是所谓的原生注射）

ITestResult对象代表测试结果。
Method表示实际方法的对象。
ITestContext对象代表正在执行的<test>。

有关所有这些内容的更多信息，请访问official documentation site。

要解决您的问题，您有两种方法可以解决问题。

方法1（这不会让你并行运行测试）

从

@BeforeMethod

@BeforeMethod
public void setup (){
    System.setProperty("webdriver.chrome.driver", "D:/Drivers/chromedriver.exe");
    WebDriver driver = new ChromeDriver();
    driver.get("wwww.hhg.com");
}

这样的事情：

private WebDriver driver = null;

@BeforeMethod
public void setup (){
    System.setProperty("webdriver.chrome.driver", "D:/Drivers/chromedriver.exe");
    driver = new ChromeDriver();
    driver.get("wwww.hhg.com");
}

您的代码正在使用WebDriver中的本地@BeforeMethod变量。改变后的版本基本上利用了数据成员，而@BeforeMethod只是实例化它。您还需要从WebDriver方法中删除@Test参数。

方法2

您使用方法1中提到的相同详细信息，但您使用的是ThreadLocal变体，而不是常规WebDriver对象。您可以从我的博客文章here中了解有关使用ThreadLocal变量的更多信息。
