To perform data-driven testing code for Selenium with Java and read input from an Excel sheet or CSV file, we’ll use Apache POI for Excel or OpenCSV for CSV.

Below is an example of how to perform data-driven testing for product feedback functionality in an e-commerce application using multiple input values from an Excel sheet or a CSV file.

Data-Driven Testing using Excel (Apache POI):
org.apache.poi poi 5.0.0

Example:
import org.apache.poi.ss.usermodel.*;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;

public class ProductFeedbackTest {

public static void main(String[] args) throws IOException {
    WebDriver driver = new ChromeDriver();
    driver.get("your_ecommerce_application_url");

    FileInputStream file = new FileInputStream(new File("path/to/your/excel_file.xlsx"));
    Workbook workbook = new XSSFWorkbook(file);
    Sheet sheet = workbook.getSheetAt(0);

    for (int i = 1; i <= sheet.getLastRowNum(); i++) {
        Row row = sheet.getRow(i);
        String productName = row.getCell(0).getStringCellValue();
        String feedback = row.getCell(1).getStringCellValue();

        // Perform the necessary steps to navigate to the product and submit feedback
        driver.findElement(By.id("product-search")).sendKeys(productName);
        driver.findElement(By.id("submit-search")).click();

        // Fill the feedback form and submit
        driver.findElement(By.id("feedback-text")).sendKeys(feedback);
        driver.findElement(By.id("submit-feedback")).click();

        // Add verification steps based on your application's behavior
    }

    driver.quit();
}

}

Finally, after processing all rows in the Excel sheet, we clean up by quitting the WebDriver, which closes the browser window.

This code demonstrates how to perform data-driven testing in Selenium with Java by reading input from an Excel sheet. You can adapt it to your specific e-commerce application and feedback functionality by adjusting the element locators and verification steps accordingly.

You can customize this script to match the structure of your application and the specifics of your test data. This is just a basic example to demonstrate the concept of data-driven testing code for Selenium with Java.
