无法在 java 上使用 @Factory testng 注释运行并行测试

Question

所以我使用@Factory 对 5 封不同的电子邮件运行一项测试，但我得到 error number of arguments 异常，并且在控制台上看不到完整的错误跟踪。我使用TestNG。这是我的代码：

package com.task.lab.facadetask;

public class GmailTest {
    private WebDriver driver;
    private static List<User> usersList;
    static List<TestMessage> mess;

    public GmailTest(){}


    @Factory(dataProviderClass = GmailTest.class, dataProvider = "getData")
    public GmailTest(WebDriver driver,List<User> usersList, List<TestMessage> mess ){
        this.driver = driver;
        GmailTest.usersList = usersList;
        GmailTest.mess = mess;
    }

    @BeforeMethod
    public void setUpDriver(){
        driver = DriverObject.getDriver();
    }

    @DataProvider
    public static Object[][] getData() {
        File usersXml = new File("src\\\\main\\\\java\\\\com\\\\task\\\\lab\\\\facadetask\\\\testdata\\\\users.xml");

        try {
            usersList = JAXB.unmarshal(usersXml);
        } catch (JAXBException e) {
            e.printStackTrace();
        }
        TestMessages messages =  UnMarshell.unmarshaller();
        assert messages != null;
        mess = messages.getTestMessages();
        return new Object[][]{
                {mess.get(0), usersList.get(0)},
                {mess.get(1), usersList.get(1)},
                {mess.get(2), usersList.get(2)},
        };
    }

    @Test
    public void testGmail(TestMessage message, User users) {
        String gmailURL = "https://accounts.google.com/signin";
        driver.get(gmailURL);
        Login loginPage = new Login();
        loginPage.login(users.getEmail(), users.getPassword());
        GmailMessage gmailPage = new GmailMessage();
        gmailPage.sendMessage(message.getReceiver(), message.getSubject(), message.getMessage());
        gmailPage.removeMessage();
        Assert.assertTrue(gmailPage.isRemoved());
    }
    @AfterMethod
    public void quitBrowser(){
        try{
            driver.close();
        }finally{
            driver.quit();
        }
    }
}

我的假设是它可能是由于将原始的非静态用户和消息列表更改为静态引起的，但 DataProvider 方法需要是静态的。有人可以指导我做错什么吗？ UPD：所以，我按照 Krishnan 的建议删除了 @BeforeMethod 并将驱动程序包含在 @DataProvider 中，但它给了我同样的错误，错误的参数数量。下面是 DataProvider 现在开始的内容：

@DataProvider
public static Object[][] getData() {
    driver = DriverObject.getDriver();
    File usersXml = new File   //The rest remains the same

另外，我尝试在 BeforeMethod 中初始化驱动程序，但在这种情况下，Test 看不到它。它看起来像这样：

@BeforeMethod
public void setUpDriver(){
    WebDriver driver = DriverObject.getDriver();
}

也许有人可以为我提供一个有效的 Factory 类似物，以便我可以同时运行 5 个并行测试？我愿意接受建议。

Answer 1

您的工厂方法被定义为接受 3 个参数。

@Factory(dataProviderClass = GmailTest.class, dataProvider = "getData")
public GmailTest(WebDriver driver,List<User> usersList, List<TestMessage> mess ){
    this.driver = driver;
    GmailTest.usersList = usersList;
    GmailTest.mess = mess;
}

您的数据提供者仅提供 2 个参数。您的数据提供商未提供 WebDriver。

您可以执行以下操作之一：

• 通过调用DriverObject.getDriver() 增强您的数据提供程序以包含WebDriver 对象并删除您的@BeforeMethod 方法（或）
• 将构造函数的签名更改为不接受 WebDriver 实例，但通过 @BeforeMethod 初始化类的 WebDriver 实例。

这应该可以解决您的问题。

编辑：问题已更新。所以也更新我的答案。

看问题的更新，答案在高层次上还是一样的。现在还包括一个示例，它解释了答案。

模拟 User 类的外观

import java.util.ArrayList;
import java.util.List;

public class User {
    private String name;

    public User(String name) {
        this.name = name;
    }

    public String getName() {
        return name;
    }

    public static List<User> newUsers(String... names) {
        List<User> users = new ArrayList<>();
        for (String name : names) {
            users.add(new User(name));
        }
        return users;
    }
}

模拟 TestMessage 类的样子

import java.util.ArrayList;
import java.util.List;
import java.util.UUID;

public class TestMessage {
    private String text;

    public TestMessage(String text) {
        this.text = text;
    }

    public String getText() {
        return text;
    }

    public static List<TestMessage> newMessages(int howMany) {
        List<TestMessage> msgs = new ArrayList<>();
        for (int i = 0; i < howMany; i++) {
            msgs.add(new TestMessage(UUID.randomUUID().toString()));
        }
        return msgs;
    }
}

测试类应该是这样的

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.Assert;
import org.testng.annotations.AfterClass;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Factory;
import org.testng.annotations.Test;

import java.util.Collections;
import java.util.List;

public class GmailTest {
    private WebDriver driver;
    private List<User> users;
    private List<TestMessage> testMessages;

    @Factory(dataProvider = "getData")
    public GmailTest(WebDriver driver, List<User> users, List<TestMessage> testMessages) {
        this.driver = driver;
        this.users = users;
        this.testMessages = testMessages;
    }

    @Test
    public void testMethod() {
        Assert.assertNotNull(driver);
        Assert.assertNotNull(users);
        Assert.assertNotNull(testMessages);
    }

    @AfterClass
    public void cleanupDrivers() {
        if (driver != null) {
            driver.quit();
        }
    }

    @DataProvider(name = "getData")
    public static Object[][] getData() {
        List<User> users = User.newUsers("Jack", "Daniel", "John");
        int size = users.size();
        List<TestMessage> testMessages = TestMessage.newMessages(size);
        Object[][] data = new Object[size][1];
        for (int i = 0; i < size; i++) {
            data[i] = new Object[]{new FirefoxDriver(), Collections.singletonList(users.get(i)),
                    Collections.singletonList(testMessages.get(0))};
        }
        return data;
    }
}

这是执行日志
