How does Selenium WebDriver verify successful login?

Hey Tim,

I would love to reply to your query, so to verify a successful login, you must follow the below points.

  • Create an instance for Selenium WebDriver.
  • Configure the browser if needed.
  • Navigate to the web page.
  • Locate the desired WebElement.
  • Perform some actions on the WebElement.
  • Verify and validate the action.

Hope my answer was helpful. To learn more about various login scenarios, follow this blog on how to automate the login page.

To verify a successful login using Selenium WebDriver, start by creating and configuring an instance of the WebDriver. After navigating to the login page, you’ll want to interact with the necessary web elements, such as the username and password fields, and the login button. Once the actions are performed, verification involves checking if the expected changes occurred on the web page, such as the appearance of specific elements that only show post-login. For detailed examples of handling various login scenarios, consider checking out resources like the LambdaTest blog on automating login pages.

Building on Tim’s method, another robust way to confirm a login’s success is by using assertions in Selenium. After executing the login, you can enhance the reliability of your test by asserting the presence of elements that should appear after a successful login. For instance, verifying a welcome message ensures that the user has genuinely accessed their dashboard. Here’s a snippet to demonstrate this:

WebElement welcomeMessage = driver.findElement(By.xpath("//span[contains(text(),'Welcome')]"));
Assert.assertTrue(welcomeMessage.isDisplayed());

This method ensures that your tests are not only checking for UI changes but are also validating that the correct UI elements are visible post-login.

Adding to what Ian mentioned, incorporating the Page Object Model (POM) enhances maintainability and readability of your test scripts. By abstracting the login page and subsequent pages into separate classes, you streamline the process of writing and updating tests. For instance, after logging in through a LoginPage object, you can transition to a DashboardPage object, which might look something like this:

LoginPage loginPage = new LoginPage(driver);
loginPage.login("username", "password");
DashboardPage dashboardPage = new DashboardPage(driver);
Assert.assertTrue(dashboardPage.isDashboardDisplayed());

This approach not only confirms the login but also simplifies interactions with the webpage by treating pages as objects, making your tests easier to manage and more scalable.
