Selenium中的数据提供者与TestNG不匹配

我正在下面的代码写在selenium和下面的错误显示，请让我知道问题在哪里。

import org.testng.annotations.DataProvider; import org.testng.annotations.Test;

public class testngexcel { public static ExcelReader excel = null; @Test(dataProvider = "newdata") public void testData(String username, String password, Integer age) { System.out.println(username + " - " + password + " - " + age); } @DataProvider(name = "newdata") public static Object[][] getData() { if (excel == null) { excel = new ExcelReader("C:\\Users\\Anjali.Nautiyal\\Desktop\\selenium\\testngdata.xlsx"); } String sheetName = "login"; int rows = excel.getRowCount(sheetName); int cols = excel.getColumnCount(sheetName); Object[][] data = new Object[rows - 1][cols]; for (int rowNum = 2; rowNum <= rows; rowNum++) { for (int colNum = 0; colNum < cols; colNum++) { data[rowNum - 2][colNum] = excel.getCellData(sheetName, colNum, rowNum); } } return data; 

错误：

我看到的唯一的问题是，你正在阅读的Excel中，所以可能是所有的值都在String ，除非你把它转换为Integer 。 然而，在你的testing中，你期望第三个参数的age是Integer

将types更改为String应该可以解决问题

 @Test(dataProvider = "newdata") public void testData(String username, String password, String age) { System.out.println(username + " - " + password + " - " + age); } 

下面的代码会引发同样的错误。

 @DataProvider(name = "newdata") public static Object[][] getData() { return new Object[][]{ {"20"}, {"30"} }; } @Test(dataProvider = "newdata") public void testData(Integer age) { System.out.println(age); }
