Handling Dynamic Web Tables in Java Selenium: Example Program

Web tables are a fundamental part of many web applications, presenting data in a structured format. However, dealing with dynamic web tables using Java Selenium automation can be tricky due to their ever-changing nature. In this guide, we’ll explore how to effectively handle these dynamic tables using Selenium with Java, along with an illustrative example program.

Understanding Dynamic Web Tables

Dynamic web tables are tables whose contents, rows, or columns change dynamically based on user interactions, inputs, or backend updates. They pose a challenge for test automation as their structure isn’t static and may require different approaches to locate and interact with elements.

Approaches to Handle Dynamic Web Tables

1. Locating Elements Using XPath or CSS Selectors

XPath and CSS selectors are robust methods to locate elements within HTML. For dynamic tables, XPath expressions or CSS selectors can be used to identify rows, columns, or specific cells based on their attributes or positions.

2. Using Selenium’s FindElements() Method

Selenium’s findElements() method helps capture multiple elements that match a specified locator strategy. Iterating through these elements allows extraction of data or performing actions on them.

3. Working With Table Element Properties

Understanding the structure and properties of the table elements (such as <tr>, <td>, <th>) assists in traversing and interacting with the dynamic table contents.

Example Program

Let’s consider a scenario where we need to retrieve data from a dynamic table on a web page. Here’s a Java Selenium code snippet to demonstrate how to extract table data:

// Import necessary Selenium libraries
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;

public class DynamicTableExample {
public static void main(String[] args) {
// Set the WebDriver path (ensure proper WebDriver setup)
System.setProperty(“webdriver.chrome.driver”, “path_to_chromedriver”);

// Initialize ChromeDriver
WebDriver driver = new ChromeDriver();

// Navigate to the web page
driver.get(“https://example.com”);

// Locate the table
WebElement table = driver.findElement(By.id(“dynamicTableId”));

// Find all rows within the table
java.util.List<WebElement> rows = table.findElements(By.tagName(“tr”));

// Iterate through rows and print cell data
for (WebElement row : rows) {
java.util.List<WebElement> cells = row.findElements(By.tagName(“td”));
for (WebElement cell : cells) {
System.out.print(cell.getText() + “\t”);
}
System.out.println(); // Move to the next line for the next row
}

// Close the browser
driver.quit();
}
}

This code snippet demonstrates how to find a dynamic table by its ID, extract rows and cells, and print the data within them.
