尝试下面的代码，但收到数据提供程序不匹配错误。任何人都可以帮忙吗？

package appModules;

}

  return arrayObject;

}

您传递的arrayObject返回值的数据类型不正确，您需要从数据提供程序方法中的Excel文件中获取字符串值，并且需要传入Object。

参考下面的示例，参考：

    @DataProvider
    public Iterator<Object[]> getTestData()
    {
        ArrayList<Object[]> testdata = new ArrayList<Object[]>();

        try {
            reader = new excelUtility(excelTestDataFile);
        } catch (Exception e) {
            e.printStackTrace();
        }

        sheetName = className;
        for (int rowNumber = 2; rowNumber <= reader.getRowCount(sheetName); rowNumber++) {
            String caseNo = reader.getCellData(sheetName, "Case", rowNumber);
            String emailid = reader.getCellData(sheetName, "Email ID", rowNumber);
            String password = reader.getCellData(sheetName, "Password", rowNumber);
            String message = reader.getCellData(sheetName, "Expected Result", rowNumber);

            Object ob[] =
            { caseNo, emailid, password, message };
            testdata.add(ob);
        }
        return testdata.iterator();
    }

这是@Test数据提供者接收者：

    @Test(dataProvider = "getTestData")
    public void calllogin(String caseNO, String emailid, String password, String expectedResult) throws Exception
    {
     ******
    }
