如何在 Selenium WebDriver 中使用 Java 和 TestNG 中的 DataProvider 读取 excel 表中的多组值

Question

我对 Selenium WebDriver 还很陌生。我编写了代码来使用数据提供程序从 excel 表中读取登录凭据和值。 它贯穿第一个设置数据（登录功能），完美地给了我绿色状态栏。

在我的应用程序中，登录后，我想通过从同一个 Excel 表中发送索引和选择（在管理方法中）来选择值，但我未能读取值。 对于硬编码值，它工作正常。

谁能告诉我如何写它。 用过的 Excel 表：

下面是我的代码：

import java.io.File;

import jxl.Sheet;
import jxl.Workbook;

import org.testng.annotations.BeforeSuite;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;
import org.junit.AfterClass;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
//import org.testng.annotations.BeforeClass;

public class TestCase {

String[][] tabArray = null;
Workbook workbk;
Sheet sheet;
int rowCount, colCount;
String sheetPath = "test/Resources/Data/Auto_Increment.xls";
WebDriver login;
//int eRow, eCol, sRow = 0, sCol = 0;


@BeforeSuite
public void setUp(){
    login = new FirefoxDriver();
    login.get("http://etazo.tangosoftware.com");
    System.out.println("select the etazo web link..");
}

@DataProvider
public Object[][] getLoginData() throws Exception {
    Object[][] retObjArr = getExcelData(sheetPath, "Sheet1");
    System.out.println("getData function executed!!");
    return retObjArr;
}

//  Excel API to read test data from excel workbook
public String[][] getExcelData(String xlPath, String shtName)
        throws Exception {
    Workbook workbk = Workbook.getWorkbook(new File(xlPath));
    Sheet sht = workbk.getSheet(shtName);
    rowCount = sht.getRows();
    colCount = sht.getColumns();
    tabArray = new String[rowCount][colCount - 2];
    System.out.println("erow: " + rowCount);
    System.out.println("ecol: " + colCount);
    for (int i = 0; i < rowCount; i++) {
        for (int j = 0; j < 3; j++) {
            tabArray[i][j] = sht.getCell(j, i).getContents();
        }
    }
    return (tabArray);
}

@Test(dataProvider = "getLoginData")
public void LoginData(String distID, String asmtId, String studID)
        throws InterruptedException, BiffException, IOException {
    Administartion(distID, asmtId, studID);
}
public void Administartion(String distID, String asmtId, String studID)
        throws BiffException, IOException {
    Workbook workbk = Workbook.getWorkbook(new File(sheetPath));
    Sheet sht = workbk.getSheet("Sheet1");
    int currRow = sht.findCell(studID).getRow();
    //login.findElement(By.xpath("//*[@id='question-"+sIndex+"']/bubbles/circle["+sValue+"]")).click();     
    System.out.println(sht.getCell(3, currRow).getContents() + " Index ");
    System.out.println(sht.getCell(4, currRow).getContents() + " Answer selection");
}

}

编辑了代码。现在这将获取所有记录。

您的 Excel 工作表应类似于以下内容：

import java.io.File;
import java.io.IOException;
import jxl.Sheet;
import jxl.Workbook;
import jxl.read.biff.BiffException;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;

public class TestClass {
    String[][] tabArray = null;
    Workbook workbk;
    Sheet sheet;
    int rowCount, colCount;
    String sheetPath = "D:\\Download\\Auto_Increment.xls";

    // Excel API to read test data from excel workbook
    public String[][] getExcelData(String xlPath, String shtName)
            throws Exception {
        Workbook workbk = Workbook.getWorkbook(new File(xlPath));
        Sheet sht = workbk.getSheet(shtName);
        rowCount = sht.getRows();
        colCount = sht.getColumns();
        tabArray = new String[rowCount][colCount - 2];
        System.out.println("erow: " + rowCount);
        System.out.println("ecol: " + colCount);
        for (int i = 0; i < rowCount; i++) {
            for (int j = 0; j < 3; j++) {
                tabArray[i][j] = sht.getCell(j, i).getContents();
            }
        }
        return (tabArray);
    }

    @DataProvider
    public Object[][] getLoginData() throws Exception {
        Object[][] retObjArr = getExcelData(sheetPath, "Sheet1");
        System.out.println("getData function executed!!");
        return retObjArr;
    }

    @Test(dataProvider = "getLoginData")
    public void LoginData(String distID, String asmtId, String studID)
            throws InterruptedException, BiffException, IOException {
        Administartion(distID, asmtId, studID);
    }

    public void Administartion(String distID, String asmtId, String studID)
            throws BiffException, IOException {
        Workbook workbk = Workbook.getWorkbook(new File(sheetPath));
        Sheet sht = workbk.getSheet("Sheet1");
        int currRow = sht.findCell(studID).getRow();
        System.out.println(sht.getCell(3, currRow).getContents() + " Index ");
        System.out.println(sht.getCell(4, currRow).getContents() + " Answer selection");
    }
}

使用的依赖项：

<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi</artifactId>
    <version>3.13</version>
</dependency>

<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-ooxml</artifactId>
    <version>3.13</version>
</dependency>

<dependency>
    <groupId>org.testng</groupId>
    <artifactId>testng</artifactId>
    <version>6.14.3</version>
    <scope>test</scope>
</dependency>

代码在这里读取 xlsx 文件：

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;

import org.apache.poi.openxml4j.exceptions.InvalidFormatException;
import org.apache.poi.ss.usermodel.DataFormatter;
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;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;

public class TestDataProvider {
    static File resultFile = new File(“PATH OF THE EXCEL”);
    public static DataFormatter formatter = new DataFormatter();

    @Test(dataProvider = "readExcelFile")
    public static void test1(String slNum, String name, String Address, String email) throws  IOException {
        System.out.println(slNum+" "+ name+" "+Address + " "+email);

    FURTHER CODE GOES HERE


    }

    @DataProvider
    public static Object[][] readExcelFile() throws InvalidFormatException, IOException {
        FileInputStream fis = new FileInputStream(resultFile);
        XSSFWorkbook wb = new XSSFWorkbook(fis);
        XSSFSheet sh = wb.getSheet(“SHEET NAME”);

        System.out.println(sh.getPhysicalNumberOfRows());
        System.out.println(sh.getRow(0).getPhysicalNumberOfCells());
        int RowNum = sh.getPhysicalNumberOfRows();
        int ColNum = sh.getRow(0).getPhysicalNumberOfCells();

        String[][] xlData = new String[RowNum-1][ColNum];

        for (int i = 0; i < RowNum - 1; i++) 
        {
            XSSFRow row = sh.getRow(i + 1);
            for (int j = 0; j < ColNum; j++) 
            {
                if (row == null)
                    xlData[i][j] = "";
                else {
                    XSSFCell cell = row.getCell(j);                 
                    if (cell == null)
                        xlData[i][j] = ""; 
                    else {
                        String value = formatter.formatCellValue(cell);
                        xlData[i][j] = value.trim();                        
                    }
                }
            }
        }       
        return xlData;
    }   
}
