两个测试一个接一个

Question

我在我的WebDriver测试中遇到问题。

在第一个包我有2个类（页）HomePage，LoginPage。

在secound包中我有测试 - goToLiginPageTest和LoginTest。

在goToLiginPage我检查，我在主页上，进入登录页面。

在LoginTest中检查我是否在登录页面并登录。

但是来自goToLiginPageTest的两个测试通过，但是来自LoginTest的测试失败。

我不确定这是不是我的textng.xlm错误，或者我犯了错误。请帮帮我。

public class HomePage { 
    WebDriver driver; 

    public static final String PAGE_TITLE = "page title"; 
    public static final String PAGE_URL = "www.blbl.pl"; 

@FindBy(xpath = "//*[@id='global-nav']/div/div/div[3]/ul/li[1]/a") 
WebElement LogInLink; 

    public HomePage(WebDriver driver){ 
     this.driver = driver; 
    } 

    public void isHomePage(){ 
     String pageTitle = driver.getTitle(); 
     Assert.assertEquals(pageTitle, PAGE_TITLE); 
    } 

    public void goToLoginPage(){ 
     LogInLink.click(); 
    } 
} 

LoginPage

public class LoginPage { 
WebDriver driver; 

public static final String PAGE_TITLE = "Login"; 

@FindBy(id="user_email") 
WebElement inputUserEmail; 

@FindBy(id="user_password") 
WebElement inputUserPassword; 


public LoginPage(WebDriver driver){ 
    this.driver = driver; 
} 

public void isLoginPage(){ 
    String pageTitle = driver.getTitle(); 
    Assert.assertEquals(pageTitle, PAGE_TITLE); 
} 

public void fillUserEmail(){ 
    inputUserEmail.sendKeys("asdfasd@gmail.com"); 
    Assert.assertEquals(inputUserEmail.getAttribute("value"), "asdfasd@gmail.com"); 
} 

public void fillUserPassword(){ 
    inputUserPassword.sendKeys("123456"); 
    Assert.assertEquals(inputUserPassword.getAttribute("value"), "123456"); 
} 

} 

GotoLoginPageTest

import pages.HomePage; 

public class GotoLoginPageTest { 
    WebDriver driver; 
    HomePage hp; 


    @BeforeClass 
    public void setup(){ 
     this.driver = new FirefoxDriver(); 
     hp = PageFactory.initElements(driver, HomePage.class); 
     driver.get(HomePage.PAGE_URL); 
    } 

    @Test(priority = 1) 
    public void isHomePage(){ 
     hp.isHomePage(); 
    } 

    @Test(dependsOnMethods = "isHomePage") 
    public void gotoLoginPage(){ 
     hp.goToLoginPage(); 
    } 

} 

LoginTest

public class LoginTest { 
    WebDriver driver; 

    LoginPage lp = PageFactory.initElements(driver, LoginPage.class); 

    @Test 
    public void cheskIsLoginPage(){ 
     lp.isLoginPage(); 
    } 

    @Test 
    public void logInBase(){ 
     lp.fillUserEmail(); 
     lp.fillUserPassword(); 
    } 

} 

我的testng.xml

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd"> 
<suite name="Suite" parallel="none"> 
    <test name="Test">

     <class name="tests.GotoLoginPageTest"/> 
     <class name="tests.LoginTest"/> 
    </classes> 
    </test> <!-- Test --> 
</suite> <!-- Suite -->

Answer 1

你从来没有实例化的驱动程序在LoginTest类。在那里实例化驱动程序并将其传递给页面对象。这样的事情：

public class LoginTest { 
    WebDriver driver; 
    driver = new FirefoxDriver(); 

    LoginPage lp = PageFactory.initElements(driver, LoginPage.class); 

    @Test 
    public void cheskIsLoginPage(){ 
     lp.isLoginPage(); 
    } 

    @Test 
    public void logInBase(){ 
     lp.fillUserEmail(); 
     lp.fillUserPassword(); 
    } 
}
