Question

这些是不同包装中的各种代码。

这是我的AutoConst界面：

package generic;
public interface AutoConst 
{
    String Gecko_Key="webdriver.gecko.driver";
    String Gecko_Value="./software/geckodriver.exe";
    String Chrome_Key="webdriver.chrome.driver";
    String Chrome_Value="./software/chromedriver.exe";
    String IE_Key="webdriver.ie.driver";
    String IE_value="./software/IEDriverServer.exe";
}

这是我的BaseTest抽象类：

package generic;

import java.util.concurrent.TimeUnit;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.annotations.AfterClass;
import org.testng.annotations.AfterMethod;

public abstract class BaseTest implements AutoConst 
{
    public WebDriver driver;
    public void BrowserOpening(String url)
    {
        System.setProperty(Chrome_Key,Chrome_Value);
        driver=new ChromeDriver();
        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
        driver.manage().window().maximize();
        driver.get(url);
    }

public void BrowserClosing()
{
    driver.quit();
}
}

这是我的BasePage Abstract类：

package pom.aut;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.PageFactory;
import org.openqa.selenium.support.ui.ExpectedConditions; 
import org.openqa.selenium.support.ui.WebDriverWait;
import org.testng.Assert;
import org.testng.Reporter;
public abstract class BasePage 
{
    public WebDriver driver;
    public BasePage(WebDriver driver)
    {
        this.driver=driver;
        PageFactory.initElements(driver, this);
    }

//this method is used for verifying the title of the page
public void verifyTitle(String eTitle)
{
    WebDriverWait Wait=new WebDriverWait(driver,10);
    try
    {
        Wait.until(ExpectedConditions.titleContains(eTitle));
        Reporter.log("Title is matching");
    }
    catch(Exception e)
    {
        Reporter.log("title is not matching");
        Assert.fail();
    }
}

//this method is used to verify Element is present or not
public void verifyElementIsPresent(WebElement element)
{
    WebDriverWait Wait=new WebDriverWait(driver,10);
    try
    {
        Wait.until(ExpectedConditions.visibilityOf(element));
        Reporter.log("Element is present");
    }
    catch(Exception e)
    {
        Reporter.log("Element is not present");
        Assert.fail();
    }
}
}

这是我的Pom课程：

package pom.aut;

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

public class LoginPage 
{
WebDriver driver;
public LoginPage(WebDriver ldriver)
{
    this.driver=ldriver;
}
@FindBy(xpath="//input[@id='Email']")
private WebElement emailTB ;

@FindBy(xpath="//input[@id='Password']")
private WebElement passwordTB;

@FindBy(xpath="//button[contains(text(),'Log')]")
private WebElement loginBTN;

public void LoginAccount(String email,String password)
{
    emailTB.sendKeys(email);
    passwordTB.sendKeys(password);  
    loginBTN.click();
}
}

这是我的考试班：打包测试脚本；

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

import generic.BaseTest;
import pom.aut.LoginPage;

public class Login_tc003 extends BaseTest
{

@Test
public void testValidLoginPage()
{
    Login_tc003 login=new Login_tc003();
    login.BrowserOpening("https://dev.autkit.com/Account/Login");
    LoginPage l=new LoginPage(driver);
    l.LoginAccount("tomharry001@gmail.com", "tomharry1");
}

}

Answer 1

在您的POM类中创建一个构造函数。

public LoginPage(){
        PageFactory.initelements(driver,this);

}

希望在此之后可以尝试。

Answer 2

您的问题是尝试将按钮存储为WebElement，然后单击它。

直接执行driver.find .... click（）或使用操作。

Actions actions = new Actions(a);
actions.moveToElement(loginBTN);
actions.click();

我正在尝试处理自动化框架，并且出现了空指针异常
