提问by Anie
I am writing the below code in selenium and below error is showing, please let me know where is the issue.
我正在用 selenium 编写以下代码并显示以下错误，请告诉我问题出在哪里。
import org.testng.annotations.DataProvider; import org.testng.annotations.Test;
导入 org.testng.annotations.DataProvider; 导入 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;

The only problem I see is this, You are reading from excel so may be all the values are coming in String, unless you are converting that to Integer. However, in your test you expect third argument ageto be Integer
我看到的唯一问题是，您正在从 excel 中读取数据，因此可能所有值都在传入String，除非您将其转换为Integer. 但是，在您的测试中，您希望第三个参数age是Integer
Changing type to Stringshould resolve the issue
将类型更改为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);
}
The following code would raise the same error.
以下代码会引发相同的错误。
@DataProvider(name = "newdata")
public static Object[][] getData() {
return new Object[][]{
{"20"},
{"30"}
};
}
@Test(dataProvider = "newdata")
public void testData(Integer age) {
System.out.println(age);
}
