How To Write Selenium Code For Login Page

How To Articles

Writing Selenium code for a login page is an essential skill for any software tester or developer. In this article, I will guide you through the process of writing Selenium code specifically for a login page. So grab your favorite code editor and let’s dive in!

Setting Up Your Environment

Before we start writing Selenium code, we need to make sure we have the necessary tools and libraries installed. First, you’ll need to have the latest version of Java Development Kit (JDK) installed on your machine. You can download it from the official Oracle website and follow the installation instructions.

Next, let’s set up our Selenium WebDriver. WebDriver is a powerful tool that allows us to automate browser interactions. To start, we need to download the Selenium WebDriver JAR file from the official Selenium website. Once downloaded, you can add the JAR file to your project’s classpath.

Now that our environment is ready, let’s move on to writing the code!

Writing the Login Test

The first step is to create a new Selenium WebDriver instance and open the browser. We can do this by instantiating the WebDriver class and calling the `get()` method with the URL of the login page. For example:

WebDriver driver = new ChromeDriver();

Next, let’s locate the username and password fields on the login page. We can use the `findElement()` method to locate elements by their ID, name, class name, or any other supported locator strategy. For example, if the username field has an ID of “username”, we can locate it as follows:

WebElement usernameField = driver.findElement("username"));

Similarly, we can locate the password field and the login button. Once we have located these elements, we can interact with them by using various methods such as `sendKeys()` to enter text into the fields and `click()` to click the login button.

WebElement passwordField = driver.findElement("password"));
WebElement loginButton = driver.findElement("login-button"));


Now that we have entered the username and password and clicked the login button, we can move on to the next step.

Handling Login Success or Failure

After clicking the login button, the login page may redirect to a different page depending on the success or failure of the login attempt. To handle this, we can use the `getCurrentUrl()` method to get the current URL of the page. We can then compare this URL with the expected URL of the successful login page to determine if the login was successful.

String currentUrl = driver.getCurrentUrl();
String expectedUrl = "";

if (currentUrl.equals(expectedUrl)) {
System.out.println("Login successful!");
} else {
System.out.println("Login failed!");

And that’s it! We have successfully written Selenium code for a login page. Remember to handle any exceptions that may occur during the execution of the test, and make sure to close the browser after the test is complete.


Writing Selenium code for a login page is a crucial skill for automating browser interactions. In this article, we learned how to set up our environment, write code to interact with login page elements, and handle login success or failure. With these techniques, you can now automate the testing of login functionality in your web applications.
