1. Introduction to Checkbox

Checkboxes are interactive elements commonly used in user interfaces to enable users to select multiple options from a given set of choices. They are represented by a small square box that can be checked or unchecked. When selected, a checkmark appears within the box, indicating the user’s choice.

2. How checkboxes works

When a checkbox is clicked or tapped, its state changes from unchecked to checked, or vice versa. The value associated with the checkbox is then sent to the server when the form is submitted. This enables the server-side application to process the user’s selections and perform the necessary actions based on the chosen options.

Checkboxes in HTML, uses the <input> element with the type attribute set to “checkbox.” Here’s an example of a checkbox:

<input type="checkbox" id="checkbox1" name="sampleCheckbox" value="Option 1">
<label for="checkbox1">Option 1</label>

In this example, the <input> element represents the checkbox itself, while the <label> element provides the text associated with the checkbox. The ‘for‘ attribute in the <label> element matches the id attribute of the corresponding <input> element.

3. Locating Checkboxes in the Web Page using selenium select checkbox method

To select checkboxes using Selenium, we first need to locate them on the web page. Selenium provides various methods to find web elements based on their attributes, such as ID, class name, or XPath. Here are some commonly used methods:

• findElement(By.id("checkboxId")): Locates an element by its ID attribute.
• findElement(By.className("checkboxClass")): Locates an element by its class name attribute.
• findElement(By.xpath("//input[@type='checkbox']")): Locates checkboxes using XPath.

Choose the appropriate method based on the structure and attributes of the checkboxes in your web application.

4. How to write xpath for checkbox in selenium

In the above checkbox html code, we are having id attribute to identify checkbox. However sometime deals with a checkbox having dynamic attribute. In order to handle such types of checkboxes we can create xpath or css.

For example in above case we can create xpath as mentioned below:

// —–> for relative xpath

//input —-> This html element is input tag

//input[@name=’sampleCheckbox‘] —-> we are using name attribute of input tag

Similarly we can use different properties of a webelement to create xpath.

4. Handling Checkboxes with Selenium Select Checkbox

Once we have located the checkboxes on the web page, we can use Selenium’s WebElement class to interact with them. The WebElement class provides various methods for checkbox selection. Here are a few commonly used methods:

how to check and uncheck checkbox in selenium webdriver java

• click(): Clicks on the checkbox to select or deselect it.

How to validate if checkbox is selected or not in selenium webdriver java

• isSelected(): Checks if the checkbox is selected.

By combining these methods, we can easily select checkboxes using Selenium in Java.

5. Example: Single Checkbox using Selenium Select Checkbox

Let’s start with a simple example of selecting a single checkbox using Selenium in Java:

// Import the necessary Selenium classes
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
public class CheckboxExample {
    public static void main(String[] args) {
        // Set the path to the ChromeDriver executable
        System.setProperty("webdriver.chrome.driver", "path/to/chromedriver");
        // Create a new instance of the ChromeDriver
        WebDriver driver = new ChromeDriver();
        // Navigate to the web page containing the checkbox
        driver.get("https://www.example.com");
        //
 Locate the checkbox element
        WebElement checkbox = driver.findElement(By.id("checkboxId"));
        // Check if the checkbox is selected
        if (!checkbox.isSelected()) {
            // Click on the checkbox to select it
            checkbox.click();
        }
        // Close the browser
        driver.quit();
    }
}

In this example, we import the necessary Selenium classes, set up the ChromeDriver, navigate to a web page, locate the checkbox element using its ID, and select the checkbox if it is not already selected.

6. Example: Multiple Checkboxes using Selenium Select Checkbox

Sometimes, we need to select multiple checkboxes simultaneously. Selenium provides ways to handle such scenarios as well. Here’s an example of how to select multiple checkbox using Selenium Select Checkbox:

// Import the necessary Selenium classes
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
public class MultipleCheckboxesExample {
    public static void main(String[] args) {
        // Set the path to the ChromeDriver executable
        System.setProperty("webdriver.chrome.driver", "path/to/chromedriver");
        // Create a new instance of the ChromeDriver
        WebDriver driver = new ChromeDriver();
        // Navigate to the web page containing multiple checkboxes
        driver.get("https://www.example.com");
        // Locate all the checkbox elements
        List<WebElement> checkboxes = driver.findElements(By.className("checkboxClass"));
        // Iterate over the checkboxes and select each one
        for (WebElement checkbox : checkboxes) {
            // Check if the checkbox is selected
            if (!checkbox.isSelected()) {
                // Click on the checkbox to select it
                checkbox.click();
            }
        }
        // Close the browser
        driver.quit();
    }
}

In this example, we locate all the checkboxes on a web page using their class name and iterate over them to select each checkbox that is not already selected.
