java - Selenium 与 TestNG 和 Java 中的数据提供程序不匹配错误 | org.testng.internal.reflect.MethodMatcherException

Question

我在使用 testNG、Selenium WebDriver 和 Java“读取”Excel 文件时遇到问题。我已经尝试过: 1.将.xlsx更改为.xls(XSSF更改为HSSF) 2.将Excel的数据类型更改为文本或常规 3. 将 ' 添加到我的测试数据

这是错误消息:

org.testng.internal.reflect.MethodMatcherException:

这是我的 Excel 阅读类(class):

package com.travelers.helpers;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.ss.usermodel.Sheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.util.Iterator;

public class ExcelHelper {

    public static Object[][] readExcelFile(File file) throws IOException {

        InputStream inputStream = new FileInputStream(file);
        XSSFWorkbook workbook = new XSSFWorkbook(inputStream);
        Sheet sheet = workbook.getSheetAt(0);
        int rowNumbers = sheet.getLastRowNum();
        int colNumbers = sheet.getRow(0).getLastCellNum();
        String[][] data = new String[rowNumbers][colNumbers];

        for(int i=0;i<rowNumbers;i++) {
            Row row = sheet.getRow(i+1);
            for(int j=0;j<row.getLastCellNum();j++) {
                data[i][j] = row.getCell(j).getStringCellValue();
            }
        }

        return data;

    }

    public static void main(String[] args) throws IOException {
        Object[][] data = readExcelFile(new File("src//main//resources//files//Dane.xlsx"));
        System.out.println(data[0][0]);
        System.out.println(data[0][1]);
    }

}

这是我的测试类(class):

package com.travelers.tests;

import com.travelers.helpers.ExcelHelper;

        driver.get("http://www.kurs-selenium.pl/demo/");
        HomePage homePage = new HomePage(driver);
        homePage.setCityHotel(city);

        homePage.openTravellersModal();
        homePage.addAdult();
        homePage.addChild();
        homePage.performSearch();

        ResultPage resultPage = new ResultPage(driver);

        List<String> hotelNames = resultPage.getHotelNames();

        //SeleniumHelper.takeScreenshot(driver);

        return data;
    }
}

Answer 1

测试数据与测试方法参数不匹配导致错误。

解决方案:

@Test(dataProvider = "getData")
    public void searchHotelTest(String city, String checkInDate, String checkOutDate, String fHotel, String fPrice,
            String sHotel, String sPrice, String tHotel, String tPrice) {

        System.out.println("City:" + city);
    }

数据提供者:

@DataProvider
    public Object[][] getData() {
        Object[][] data = null;

        String city = "Bilimora";
        String checkInDate = "checkInDate";
        String checkOutDate = "checkOutDate";
        String fHotel = "fHotel";
        String fPrice = "fPrice";
        String sHotel = "sHotel";
        String sPrice = "sPrice";
        String tHotel = "tHotel";
        String tPrice = "tPrice";
        data = new Object[][] { { city, checkInDate, checkOutDate, fHotel, fPrice, sHotel, sPrice, tHotel, tPrice } };
        return data;
    }

返回类型为二维数组的 DataProvider 用于使用不同的数据执行相同的测试次数。

为了说清楚，

public class DP
{
 @DataProvider (name = "data-provider")
 public Object[][] dpMethod(){
 return new Object[][] {{"First-Value"}, {"Second-Value"}};
 }

    @Test (dataProvider = "data-provider")
    public void myTest (String val) {
        System.out.println("Passed Parameter Is : " + val);
    }
}

输出:

PASSED: myTest("First-Value")
PASSED: myTest("Second-Value")
