org.testng.TestNGException：无法实例化 class test.AddCustomerTest

Question

我正在尝试将此代码作为 eclipse 中的 maven 项目运行，但是当我尝试将测试作为 TestNG 运行时出现错误。 这是我的所有代码：

util(包) ExcelReader.java

package util;

import java.io.FileInputStream;

import org.apache.poi.xssf.usermodel.XSSFCell;
import org.apache.poi.xssf.usermodel.XSSFRow;
import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;

public class ExcelReader {

    //Global Variables
    public String path;
    public FileInputStream fis = null;
    private XSSFWorkbook workbook = null;
    private XSSFSheet sheet = null;
    private XSSFRow row = null;
    private XSSFCell cell = null;

    // Constructor to initialize variables
    public ExcelReader(String path) {
    this.path = path;
    try {
    fis = new FileInputStream(path);
    workbook = new XSSFWorkbook(fis);
    sheet = workbook.getSheetAt(0);
    fis.close();
    } catch (Exception e) {
    e.printStackTrace();
    }
    }

    // Method to call the value
    public String getCellData(String sheetName, String colName, int rowNum) {
    // For Sheet
    int index = workbook.getSheetIndex(sheetName);
    int col_Num = 0;
    sheet = workbook.getSheetAt(index);

    // For Row
    row = sheet.getRow(0);
    for (int i = 0; i < row.getLastCellNum(); i++) {
    if (row.getCell(i).getStringCellValue().trim().equals(colName.trim())) {
    col_Num = i;
    }
    }

    // For Column
    row = sheet.getRow(rowNum - 1);
    cell = row.getCell(col_Num);
    return cell.getStringCellValue();
    }
    
}

src/test AddCustomerTest

package test;

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

import page.AddCustomersPage;
import page.DashboardPage;
import page.LoginPage;
import util.BrowserFactory;
import util.ExcelReader;

public class AddCustomerTest {

    WebDriver driver;

    ExcelReader exlread = new ExcelReader("TestData\\Test.xlsx");
    String userName = exlread.getCellData("LoginInfo", "UserName", 2);
    String password = exlread.getCellData("LoginInfo", "Password", 2);
    String fullname = exlread.getCellData("AddContactInfo", "FullName", 2);
    String companyName = exlread.getCellData("AddContactInfo", "CompanyName", 2);
    String email = exlread.getCellData("AddContactInfo", "Email", 2);
    String phoneNum = exlread.getCellData("AddContactInfo", "Phone", 2);
    String addresss = exlread.getCellData("AddContactInfo", "Address", 2);
    String country = exlread.getCellData("AddContactInfo", "Country", 2);
    String city = exlread.getCellData("AddContactInfo", "City", 2);
    String state = exlread.getCellData("AddContactInfo", "State", 2);
    String zip = exlread.getCellData("AddContactInfo", "Zip", 2);

    @Test
    public void validUserShouldBeAbleToAddCustomer() {

        driver = BrowserFactory.init();

        LoginPage loginpage = PageFactory.initElements(driver, LoginPage.class);
        loginpage.enterUserName("demo@techfios.com");
        loginpage.enterPassword("abc123");
        loginpage.clickSignInButton();

        DashboardPage dashboardpage = PageFactory.initElements(driver, DashboardPage.class);
        dashboardpage.validateDashboardPage();

        AddCustomersPage addcustomer = PageFactory.initElements(driver, AddCustomersPage.class);
        addcustomer.clickOnCustomerButton();
        addcustomer.clickOnADDCustomerButton();
        addcustomer.enterFullName(fullname);
        addcustomer.enterCompanyName("companyName");
        addcustomer.enterEmail("email");
        addcustomer.EnterPhoneNumber("phoneNum");
        addcustomer.EnterAddress("addresss");
        addcustomer.EnterCountry(country);
        addcustomer.EnterCity("city");
        addcustomer.EnterCountry(state);
        addcustomer.EnterCountry(zip);
        addcustomer.clickSaveButton();
        addcustomer.clickListCustomerButton();

        // BrowserFactory.tearDown();

    }

}

Answer 1

这是答案：

这意味着当您的 class 被静态初始化时， AddCustomerTest.java:18行。 它转到您的ExcelReader ，该类尝试通过其名称获取工作表的索引，但它返回-1 ，这意味着（如果您查看文档）它无法找到具有给定名称LoginInfo的工作表。
