Question

问题： 我是 selenium 和自动化测试的初学者，我正在使用 java、TestNG 和 maven 编写 selenium 脚本。当我将所有内容都写在一个 class 中时，一切正常，但我想要一个包含所有对象的包，一个用于测试的包，以及具有主要设置的 Base Class。该项目将为网站的每个页面包含一个 class，并为所有测试包含一个 class。 当我尝试修改某些内容时，另一个错误来自 BaseClass 中的构造函数，我不知道为什么基础class是这样的：

我试过的

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

或 PagegeFactory.initElements(new AjaxElementLocatorFactory(driver, TimeoutValue), this); 并没有奏效。

package com.selenium.Base;
import org.openqa.selenium.By;
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
import org.testng.annotations.*;
import page_objects.AnalizesiPreturi;

import java.util.concurrent.TimeUnit;

public class BaseClass  {


    public WebDriver driver;
    protected static AnalizesiPreturi baseClass;

    public BaseClass(WebDriver driver) {  }

    public BaseClass() {    }

    @BeforeMethod
    public void setUp() {

        System.setProperty("webdriver.driver.chrome", "C://SeleniumWebdrivers//chromedriver.exe");
        driver = new ChromeDriver();
        //implicit wait
        driver.manage().window().maximize();
       driver.manage().timeouts().implicitlyWait(10, TimeUnit.MINUTES);

        //launch URL
        driver.get("http://googl.com/");

        //scroll
        JavascriptExecutor js = (JavascriptExecutor) driver;
        js.executeScript("window.scrollBy(0,500)", "");

        //WebDriverWailt for all objects located by class name
        WebDriverWait wbd = new WebDriverWait(driver, 1000);
        wbd.until(ExpectedConditions.presenceOfAllElementsLocatedBy(By.className("AnalizesiPreturi")));
    }
    @AfterMethod
    public void tearDown(){
        driver.close();
    }
}

页面对象class这是来自另一个包

package page_objects;
import com.gargoylesoftware.htmlunit.Page;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.FindBy;
import com.selenium.Base.BaseClass;
import org.openqa.selenium.support.PageFactory;
import org.testng.annotations.Test;

public class AnalizesiPreturi extends BaseClass {
    public AnalizesiPreturi(WebDriver driver) {
        this.driver = driver;
        PageFactory.initElements(driver, this);
    }

    @FindBy(css = "#onetrust-accept-btn-handler")
    WebElement cookie;
    @FindBy(css = "#footable_501 > tbody > tr.ninja_table_row_0.nt_row_id_77 > td.ninja_column_1.ninja_clmn_nm_pret.footable-last-visible")
    WebElement plus1Button;
    @FindBy(css = "#footable_501 > tbody > tr.ninja_table_row_1.nt_row_id_78 > td.ninja_column_1.ninja_clmn_nm_pret.footable-last-visible")
    WebElement plus2Button;
    @FindBy(css = "#calculator > div.body > div.products > div.innerProducts > div > div.right")
    WebElement minusButton;
    @FindBy(css = "#show-hide > div.hide")
    WebElement closeButton;
    @FindBy(css = "#footable_501 > thead > tr.footable-filtering > th > form > div > div > input")
    WebElement search;
    @FindBy(css = "#footable_501 > thead > tr.footable-filtering > th > form > div > div > div > button.btn.btn-primary")
    WebElement findButton;

    @Test
    public AnalizesiPreturi addAnalises(){
        PageFactory.initElements(driver, this);
        cookie.click();
        plus1Button.click();
        plus2Button.click();
        closeButton.click();
        return null;
    }
}

最后一个是测试包

package Test;
import com.selenium.Base.BaseClass;
import org.openqa.selenium.WebDriver;
import org.testng.annotations.Test;
import page_objects.AnalizesiPreturi;
import page_objects.Centers;

public class TestsPage extends BaseClass {
    public TestsPage(WebDriver driver) {
        super(driver);
    }
    public WebDriver getDriverInstance() {
        return driver;
    }

    @Test
    public void TestAnalises()throws Exception{
        //Tests
        driver.get("");
        AnalizesiPreturi analise = new AnalizesiPreturi(driver);
        analise.addAnalises();
    }
    public void TestCenters(){
        Centers centre = new Centers(driver);
        centre.checkCenters();
    }
}

下面是收到的异常：

或

Answer 1

您需要为 TestsPage 定义默认构造函数。（不只是针对基础 class） TestNG 尝试通过以下方法创建测试 class 的对象：

循环所有构造函数：

检查是否使用 @Parameters
检查是否有任何用 @Factory 注释的构造函数。

如果没有这样的构造函数则：

最后它会检查是否使用默认构造函数创建测试 class。

所以目前您的代码不符合上述三个标准。因此例外。

尝试添加默认构造函数，它会起作用。

public TestsPage() {

}
