無法在Java上使用@Factory testng批注運行並行測試

Question

因此，我使用@Factory對5封不同的電子郵件運行一項測試，但是我得到了錯誤數量的參數異常，並且無法在控制台上看到完整的錯誤跟蹤。 我使用TestNG。 這是我的代碼：

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();
        }
    }
}

我的假設是，這可能是由於將用戶和消息的原始非靜態列表更改為靜態而引起的，但是DataProvider方法必須是靜態的。 有人可以指導我做錯什么嗎？ UPD：因此，我按照Krishnan的建議刪除了@BeforeMethod，並將驅動程序包含在@DataProvider中 ，但它給了我同樣的錯誤，錯誤的參數數量。 這是DataProvider現在開始的內容：

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

另外，我嘗試在BeforeMethod中初始化驅動程序，但在這種情況下Test看不到它。 看起來像這樣：

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

也許有人可以為我提供Factory的有效模擬，以便我可以同時運行5個並行測試？ 我願意征求意見。

Answer 1

您的工廠方法定義為接受3個參數。

@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;
}

您的數據提供商僅提供2個參數。 您的數據提供商未提供WebDriver。

您可以執行以下操作之一：

• 通過調用DriverObject.getDriver()增強數據提供程序以包含WebDriver對象，並刪除@BeforeMethod方法（或）。
• 更改構造函數的簽名以不接受WebDriver實例，而是通過@BeforeMethod初始化類的WebDriver實例。

那應該解決您的問題。

編輯：問題已更新。 所以也更新我的答案。

從問題的最新情況看，答案在很大程度上還是一樣的。 現在還包括一個樣本，解釋了答案。

模擬User類的外觀

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;
    }
}

模擬TestMessage類的外觀

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;
    }
}

這是測試類的樣子

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;
    }
}

這是執行日志
