Overview

The submit() method in Selenium WebDriver is used to submit a form in a web application. This method is typically invoked on an input element, usually a <button> or <input type="submit">, or it can be used on other form elements like text fields. When you invoke submit() on a WebElement, it triggers the form submission, simulating the action of a user clicking on a submit button or pressing the Enter key in a form field.

The submit() method is most commonly used for automating tests involving form submissions, such as user registration, login, or data entry. It is a convenient way to simulate a complete form submission without needing to manually click the submit button.

Syntax

				
					element.submit();
				
			
  • element: The WebElement on which the submit action is to be performed. Typically, this is a form field (e.g., text box) or a submit button.

Usage

The submit() method is used in scenarios where you want to automate the process of submitting a form without needing to directly click on the submit button. Some common use cases include:

  1. Submitting a Form via Input Field: This is often used when the user is expected to press Enter in a form field (like a username or search field) to submit the form.

				
					WebElement searchBox = driver.findElement(By.name("q"));
searchBox.sendKeys("Selenium WebDriver");
searchBox.submit();  // Submitting the form by invoking submit() on the input field
				
			

2. Form Submission After Entering Data: You can automate the process of filling out a form and submitting it in a single sequence, which is useful for testing registration or login functionality.

				
					WebElement usernameField = driver.findElement(By.id("username"));
WebElement passwordField = driver.findElement(By.id("password"));

usernameField.sendKeys("testuser");
passwordField.sendKeys("password123");

passwordField.submit();  // Submitting the form by invoking submit() on the password field
				
			

3. Automating Login Forms: The submit() method can be used to automate login processes without having to explicitly click the submit button.

				
					WebElement loginField = driver.findElement(By.id("login"));
WebElement passwordField = driver.findElement(By.id("password"));

loginField.sendKeys("testuser");
passwordField.sendKeys("securepassword");
passwordField.submit();  // Submitting the form using the password field
				
			

4. Handling Forms with Multiple Fields: After filling out multiple fields, you can submit the form by invoking the submit() method on the last field or the submit button.

				
					WebElement firstNameField = driver.findElement(By.id("firstName"));
WebElement lastNameField = driver.findElement(By.id("lastName"));
WebElement emailField = driver.findElement(By.id("email"));

firstNameField.sendKeys("John");
lastNameField.sendKeys("Doe");
emailField.sendKeys("john.doe@example.com");

emailField.submit();  // Submitting the form by invoking submit() on the last field (email)
				
			

Example

				
					import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;

public class SubmitFormExample {
    public static void main(String[] args) {
        // Set path to the ChromeDriver executable
        System.setProperty("webdriver.chrome.driver", "path/to/chromedriver");

        // Initialize WebDriver (ChromeDriver in this case)
        WebDriver driver = new ChromeDriver();

        // Navigate to the login page
        driver.get("https://www.example.com/login");

        // Find the username and password fields, enter the credentials, and submit the form
        WebElement usernameField = driver.findElement(By.id("username"));
        WebElement passwordField = driver.findElement(By.id("password"));

        usernameField.sendKeys("testuser");
        passwordField.sendKeys("password123");

        // Submit the form using the submit() method
        passwordField.submit();

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

Importance

The submit() method is important for several reasons:

  • Form Automation: It allows testers to simulate submitting forms with a single method call, which is essential for automating user interactions such as login, registration, or data entry in web applications.
  • Simulates Real User Behavior: It mimics real user behavior of submitting forms by either pressing the Enter key or triggering the submit button action.
  • No Need to Click Submit Button: Unlike the click() method, which requires an explicit click on the submit button, submit() can be called on any form element (even the input fields), making it a more versatile option for form submission.

Limitations

While submit() is a useful method, it has some limitations:

  • May Bypass JavaScript Handlers: If the form submission is handled by JavaScript (e.g., AJAX form submission), the submit() method may bypass the JavaScript code associated with clicking the submit button. In such cases, click() might be more appropriate.
  • Does Not Trigger Click Events: Since submit() directly triggers form submission, it does not simulate the clicking of the submit button. Therefore, if there are other actions tied to the click event of the button, those will not be triggered.
  • Form Validation: If the form has validation logic that requires specific user actions (e.g., clicking a submit button to trigger validation), using submit() on an input field might bypass these validation steps.

Conclusion

The submit() method in Selenium WebDriver is an efficient way to automate form submissions without explicitly clicking a submit button. It simulates a form submission either by pressing the Enter key on an input field or by invoking the submit functionality directly on the form or input element. While it is a convenient and powerful method for automating tests involving form submissions, it is important to consider its limitations, particularly with forms that rely on JavaScript for submission handling.

In the next section, we will explore other element interaction methods, such as click(), that allow for simulating more complex user interactions.

Key Features

  • Form Submission: submit() triggers the form submission in the same way that pressing the Enter key or clicking the submit button would.
  • Versatile Usage: It can be invoked on any form element, not just the submit button, making it flexible for various form automation tasks.
  • No Need for Click Simulation: Unlike click(), which requires you to interact with the submit button, submit() directly submits the form, streamlining the process.
