Java 如何在testng.xml中为路径指定动态值

我已经创建了一个用于读取excel值的类，该类位于一个包中，另外还有一个类用于检查登录名，它以testng的形式位于不同的类中。 我的ReadExcelFile.java是 包uat

public class ReadExcelFile extends BeforeAfterSuite{

    @Test
    @Parameters("filename")
    public void readXLSXFile(String fileName)   {
        InputStream XlsxFileToRead = null;
        XSSFWorkbook workbook = null;
        try {
            XlsxFileToRead = new FileInputStream(fileName);

            //Getting the workbook instance for xlsx file
            workbook = new XSSFWorkbook(XlsxFileToRead);
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

        //getting the first sheet from the workbook using sheet name. 
        // We can also pass the index of the sheet which starts from '0'.
        XSSFSheet sheet = workbook.getSheet("Sheet1");
        XSSFRow row;
        XSSFCell cell;

        //Iterating all the rows in the sheet
        Iterator rows = sheet.rowIterator();

        while (rows.hasNext()) {
            row = (XSSFRow) rows.next();

            //Iterating all the cells of the current row
            Iterator cells = row.cellIterator();

            while (cells.hasNext()) {
                cell = (XSSFCell) cells.next();

                if (cell.getCellType() == XSSFCell.CELL_TYPE_STRING) {
                    System.out.print(cell.getStringCellValue() + " ");
                } else if (cell.getCellType() == XSSFCell.CELL_TYPE_NUMERIC) {
                    System.out.print(cell.getNumericCellValue() + " ");
                } else if (cell.getCellType() == XSSFCell.CELL_TYPE_BOOLEAN) {
                    System.out.print(cell.getBooleanCellValue() + " ");

                } 
            }
            System.out.println();
            try {
                XlsxFileToRead.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }



}

在testng中，我想将参数作为文件名和路径一起传递，但它是硬编码的，我想发送动态值 因为我以后打算移动的位置位于共享路径中。

以下是您的操作方法

删除对@Parameters的依赖关系 利用JVM参数，比如filename，可以选择接受实际位置，如果未提供，则为JVM参数定义默认值。 您的代码可以如下所示

@Test
public void readXLSXFile()   {
    //To provide a different value for the excel sheet, use the JVM argument: -Dfilename
    //For e.g., -Dfilename=src/test/resources/anotherdata.xls
    //If this JVM argument is not provided, 
    //then the file name is defaulted to src/test/resources/data.xls
    String fileName = System.getProperty("filename", "src/test/resources/data.xls");
    InputStream XlsxFileToRead = null;
    XSSFWorkbook workbook = null;
    //Rest of the code goes here
}
