➡️Introduction:

Web tables are a common structure in web applications used to display structured data. Automating web tables in Selenium WebDriver is crucial for testing applications where data is presented in tabular format. This guide explores how to handle web tables in Selenium, extract data, and interact with table elements effectively.

➡️What is a Web Table in Selenium?

A web table is an HTML element used for organizing data in rows and columns. Selenium provides various methods to interact with web tables, retrieve data, and perform operations like clicking links, selecting checkboxes, or filling input fields inside a table.

➡️Types of Web Tables:

1. Static Web Tables: These tables have fixed data that does not change dynamically.
2. Dynamic Web Tables: These tables fetch data dynamically from a database or API, and the content changes in real-time.

➡️Locating Web Tables in Selenium:

Selenium WebDriver provides multiple locators to find web elements within tables:

• By.id()
• By.name()
• By.className()
• By.cssSelector()
• By.xpath() (Most commonly used for web tables)

➡️Extracting Data from a Web Table:

• From Beginner to Expert: Web Table Handling in Selenium WebDriver.

To retrieve data from a table cell, we use XPath to navigate through table rows (<tr>) and table cells (<td>).

Example Code:

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class WebTableExample {
    public static void main(String[] args) {
        String baseUrl = "http://demo.guru99.com/test/write-xpath-table.html";
        WebDriver driver = new FirefoxDriver();

        driver.get(baseUrl);
        String innerText = driver.findElement(By.xpath("//table/tbody/tr[2]/td[2]")).getText();
        System.out.println(innerText);
        driver.quit();
    }
}

➡️Explanation:

• //table selects the table element.
• /tbody/tr[2]/td[2] navigates to the second row and second column.
• getText() fetches the cell’s text.

➡️Handling Nested Tables:

Nested tables are tables within another table. XPath can be used to navigate through multiple layers.

➡️Example Code for Nested Tables:

public static void main(String[] args) {
    String baseUrl = "http://demo.guru99.com/test/accessing-nested-table.html";
    WebDriver driver = new FirefoxDriver();

    driver.get(baseUrl);
    String innerText = driver.findElement(By.xpath("//table/tbody/tr[2]/td[2]/table/tbody/tr/td[2]")).getText();
    System.out.println(innerText);
    driver.quit();
}

This retrieves the text from a nested table inside another table.

➡️Using Attributes as Predicates:

When an element is deeply nested, XPath attributes can be used as predicates instead of numeric indices.

Example Code:

public static void main(String[] args) {
    String baseUrl = "http://demo.guru99.com/test/newtours/";
    WebDriver driver = new FirefoxDriver();

    driver.get(baseUrl);
    String innerText = driver.findElement(By.xpath("//table[@width=\"270\"]/tbody/tr[4]/td")).getText();
    System.out.println(innerText);
    driver.quit();
}

Here, @width="270" is used to locate the table uniquely.

➡️Handling Dynamic Web Tables:

Dynamic tables require identifying elements based on changing attributes, such as unique class names or IDs.

➡️Example for Handling Dynamic Tables:

List<WebElement> rows = driver.findElements(By.xpath("//table/tbody/tr"));
int rowCount = rows.size();
System.out.println("Total rows: " + rowCount);

List<WebElement> columns = driver.findElements(By.xpath("//table/tbody/tr[1]/td"));
int colCount = columns.size();
System.out.println("Total columns: " + colCount);

This code dynamically counts the number of rows and columns in a table.

➡️Clicking Elements Inside Web Tables:

To click a button or link inside a table:

driver.findElement(By.xpath("//table/tbody/tr[3]/td[1]/a")).click();

This clicks a link inside the third row and first column.

➡️Using Inspect Element for XPath Generation:

1. Right-click the desired cell and select Inspect Element.
2. Identify the XPath using browser dev tools.
3. Use the XPath in Selenium WebDriver.

➡️Best Practices:

• Prefer Relative XPath over Absolute XPath.
• Use @attributes instead of numeric predicates where possible.
• Avoid hardcoding row and column indexes for dynamic tables.
• Utilize loops to traverse tables dynamically.

➡️Conclusion:

Handling web tables in Selenium WebDriver is essential for testing web applications effectively. Using XPath, CSS selectors, and attributes as predicates, testers can efficiently interact with table elements, retrieve data, and perform actions like clicking buttons or links within tables.
