My Java class is not running. I have a @DataProvider with Apache POI to read data from an Excel file and set that values in an web page. but the script is ending with No test found error. Here is my code :

package testCases;

import org.openqa.selenium.By;
import org.testng.Reporter;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;


import base.TestBase;

public class StudentRegistrationForm extends TestBase {

    
    @Test(dataProvider = "getData")
    public void addStudent(String fname, String email, String CurrentAddress,String PermAddress) {
        

        System.setProperty("org.uncommons.reportng.escape-output", "false");
        //driver.get(confg.getProperty("testsiteurl"));
        driver.get(confg.getProperty("url2"));
        log.debug("Navigated to : " + confg.getProperty("url2"));
        
        driver.findElement(By.cssSelector(or.getProperty("fullname"))).sendKeys(fname);
        driver.findElement(By.cssSelector(or.getProperty("email"))).sendKeys(email);
        driver.findElement(By.cssSelector(or.getProperty("currentAddress"))).sendKeys(CurrentAddress);
        driver.findElement(By.cssSelector(or.getProperty("permAddress"))).sendKeys(PermAddress);
        driver.findElement(By.cssSelector(or.getProperty("submit"))).click();
        log.debug("Completed Test 2 - Student Registration Form");
        Reporter.log("Completed Test 2 - Student Registration Form");
    }

    @DataProvider(name="getData")
    public Object[][] getData(){
        
            String SheetName = "sheet1";
    
            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;
    }
}

And here is my output in the eclipse console.

There is nothing wrong with the testng usage in your code above. This simply means there is no data being provided by the data provider. You can either put a debug point on your data object or print it to see if the data array is being initialized. Maybe your excel utility is not correctly written or an exception is being eaten inside.
