从.bat文件运行时，TestNG脚本无法打开Excel

Question

我的TestNg脚本使用DataProvider从Excel输入数据。 当我从Eclipse运行testng.xml文件时，它工作正常。 但是，当我尝试从.bat文件运行相同的文件时，它不起作用。 在尝试打开Excel文件时失败。 请帮忙。

这是我的DataProvider类：

@DataProvider(name="DataProvider")
public static Object[][] passExcelData(Method m) throws BiffException,   IOException
{
    String sheetName = m.getName();
    config = new ExcelDataConfig("inputData.xlsx", sheetName);
    int rows = config.getRowCount(sheetName);
    int cols = config.getColCount(sheetName);
    Object[][] data = new Object[rows][cols];

    for(int i=0; i<rows; i++)
    {
        for(int j=0; j<cols; j++)
        {
            data[i][j] = config.getData(sheetName, i, j);
        }
    }
    return data;
  }

下面是BeforeClass和测试调用DataProvider：

@BeforeClass
public void setup() throws InterruptedException
{
    System.setProperty("webdriver.chrome.driver", rootFolder +"Drivers\\chromedriver.exe");
    driver = new ChromeDriver();
    driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
    driver.manage().window().maximize();
    System.out.println("setup done");
}

@Test(priority = 7, dataProvider="DataProvider")
public void EmailAlerts(String Product, String URL, String username, String password) throws InterruptedException
{   
    functionName = Product + "_EmailAlerts_" +username;
    HomePage(URL);
    Login.loginProcess(username, password);
    EmailAlerts.EmailAlerts_Process();
    Logout();
}

它不会出现任何错误。 BeforeClass运行没有问题。 它会打开浏览器并显示“设置已完成”消息。 它甚至调用DataProvider类，但无法打开excel文件。 仅当我从.bat文件运行时，才会发生此问题。 如果我从excel部件中读取并进行硬编码，请在DataProvider类中输入数据-相同的bat文件可以正常工作。

我已经简化了脚本并将“详细”设置为10。以下是最新的：

public class Master {
@Test
public void sample() throws Exception 
{
    System.out.println("INSIDE SAMPLE");
    FileInputStream fis = new FileInputStream ("C:\\Automation\\Test\\inputData.xlsx");
    System.out.println("FILE");
    XSSFWorkbook wb = new XSSFWorkbook(fis);
    System.out.println("WORKBOOK");
    wb.getSheet("MyDetails");
    System.out.println("SHEET");

    System.out.println(wb.getActiveSheetIndex());
}

}

以下是从bat文件运行时的日志：

Answer 1

数据提供者方法不应引发异常。 将它们管理到您的方法中，您将了解代码的问题。

我敢打赌，您遇到类路径问题，并且与bat文件一起运行时， inputData.xlsx在预期位置不可用。

Answer 2

是的，现在解决了。 我的poi文件位于项目文件夹\\ lib \\ poi文件夹中。 我已经将它们移至项目folder \\ lib。 而且有效。 谢谢@Julien Herr。
