How To Write Test Cases For Yahoo Login Page

Hey there! Today, I want to share with you my experience and insights on writing test cases for the Yahoo login page. As a software tester, crafting effective and comprehensive test cases is crucial to ensure the functionality and security of the login process. So, let’s dive deep into the details of test case creation for the Yahoo login page!

Understanding the Yahoo Login Page

Before we start writing test cases, let’s understand the components and functionality of the Yahoo login page. The login page usually consists of:

  • Username or Email field
  • Password field
  • Remember Me option
  • Sign In button
  • Forgot Password link
  • Create New Account link
  • Error messages for invalid login attempts

Having a clear understanding of the login page elements will help us in designing effective test cases.

Test Case Scenarios

Now, let’s explore some important test case scenarios that we can consider while testing the Yahoo login page:

1. Valid Login

This test case scenario verifies if a valid username and password combination successfully logs the user into the Yahoo account. Here are the steps:

  1. Enter a valid email/username in the username field.
  2. Enter the correct password in the password field.
  3. Ensure the “Remember Me” option works as expected.
  4. Click on the “Sign In” button.
  5. Verify that the user is successfully logged in and redirected to the Yahoo account dashboard.

2. Invalid Login

This test case scenario validates the error handling of the Yahoo login page for invalid login attempts. Here’s how we can test it:

  1. Enter an invalid email/username in the username field.
  2. Enter an incorrect password in the password field.
  3. Click on the “Sign In” button.
  4. Verify that the appropriate error message is displayed for invalid credentials.
  5. Repeat the above steps with different combinations of invalid credentials.

3. Forgot Password

This test case scenario validates if the “Forgot Password” functionality is working as expected. Follow these steps to test it:

  1. Click on the “Forgot Password” link.
  2. Enter a valid email/username associated with the Yahoo account in the provided field.
  3. Click on the “Continue” button.
  4. Verify that a password reset email is sent to the entered email/username.
  5. Access the email account and verify if the password reset link is received.
  6. Click on the password reset link and ensure that the user is redirected to the password reset page.

Similarly, we can create more test cases to cover other functionalities of the Yahoo login page, such as account creation, handling special characters in username/password, validation of minimum password length, and more.


Writing test cases for the Yahoo login page is a critical step in ensuring its functionality and security. By covering various test case scenarios, we can identify potential issues and ensure a smooth user experience. Remember to consider both positive and negative test cases to cover all possible scenarios.

So, the next time you test the Yahoo login page, put on your tester hat and follow the steps we discussed above. Happy testing!
