Selenium与TestNG中的数据提供者不匹配 [英] Data provider mismatch in Selenium with TestNG

问题描述

我正在用硒编写以下代码，并且显示以下错误，请让我知道问题出在哪里.

I am writing the below code in selenium and below error is showing, please let me know where is the issue.

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

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:

推荐答案

我看到的唯一问题是，您是从excel读取的，因此可能所有值都在String中，除非您将其转换为Integer.但是，在测试中，您希望第三个参数age为Integer

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 age to be Integer

将类型更改为String应该可以解决问题

Changing type to String should resolve the issue

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

以下代码将引发相同的错误.

The following code would raise the same error.

@DataProvider(name = "newdata")
public static Object[][] getData() {
    return new Object[][]{
            {"20"},
            {"30"}
    };
}

@Test(dataProvider = "newdata")
public void testData(Integer age) {

    System.out.println(age);

}
