    Characteristics of a Login Page

    When it comes to designing a login page, the tester needs to consider various factors for better security. A great example of a well-designed login page is the Gmail login page which prompts the users to enter their login credentials to access the system.

    Furthermore, to write a login page, testers should ensure it is secure, intuitive, and user-friendly. To be precise, it should provide clear instructions for entering login credentials with two-factor authentication for ultimate security.

    Let’s have a look at the key characteristics of a login page

    • Simple and clear- The interface of the login page should be simple so that users can navigate the page and enter their login credentials.
    • Accessibility- It should be accessible to every user, including those with disabilities. Hence, the login page must also adhere to the accessibility guidelines.
    • Secure- Password encryption, automatic logout after prolonged periods of inactivity, and two-factor authentication, are the essential security features that every login page must have.
    • Scalability- The login page should be able to handle a massive number of users; thus, the server needs to have sufficient resources to handle authentication and login requests.
    • Branding- It must reflect the visual identity and branding of the particular application or the company. In this way, you can achieve brand recognition and uniform consistency across the world.
    • Customization- The login page should be easy to customize so you can add additional features such as CAPTCHA verification, password recovery, etc. After understanding the login page and its functionalities, let’s quickly understand the test cases.

    What is a Test Case?

    Test cases act as a fundamental component of the software testing process. It empowers QA experts to confirm that it meets desired expectations and is free from bugs or defects.

    Creating a comprehensive document ensures that the product meets the desired end-user standards by providing a set of predefined steps to conduct a robust testing process.

    Test Cases for Login Page Positive and Negative

    Positive and negative test cases in software testing are used to analyze the system behavior under different conditions. The major difference between both cases is the input that gets tested.

    Positive test cases verify that the system behaves according to the provided action or meets specific requirements. For example, login page positive test cases validate that a user can successfully log in with valid credentials.

    On the other hand, login page negative test cases are designed to verify the system behavior when unexpected or invalid input is provided by the users.

    Thus, these tests verify that the system must behave when it receives input outside the expected range. For example, negative test cases verify that the system displays the correct error message when the users enter an invalid username or password.

    Positive Test Cases for Login Page Examples

    These are some of the few examples of positive test cases for login page XLS.

    1. Verify that the application displays appropriate messages for successful login.
    2. Verify easy login through social media accounts.
    3. Verify that the system allows users to reset their password and log in again with a new password.
    4. Verify the users can successfully log in with a valid username and password.
    Negative Test Cases for Login Page Examples

    Examples of negative test cases for the login page in the excel sheet are listed below.

    1. Verify that the system displays appropriate error messages when a user enters an invalid username or password.
    2. Verify that the system doesn’t allow users to log in through a blank username or password field.
    3. Verify that the system displays an error message when users try to log in from an unauthorized IP address.
    4. Verify that the system logs out the user automatically after a particular period of inactivity.

    Different Components of a Login Page

    Each component of a login page serves a crucial purpose in ensuring the security and efficiency of the login process. These are some essential components of a login page.

    • Password Field- This field is added to the login page where the users can add their password to access their accounts.
    • Email or Username Field- In this section, the users enter their email address or user name linked with their account.
    • Sign Up or Create Account- Test cases for the signup page are one of the primary components of a login page where users click on this button after entering their credentials to access the application.
    • Forgot Password or Password Recovery Link- It is essential to add forgot password link in case they forget their password. Through this link, they can reset their password by verifying their identity and creating a new one.
    • Remember Me- Remember Me is an optional feature that allows users to save their login credentials for future sessions. Thus, its main motto is to make the platform easily accessible.
    • Error Messages- When a user enters incorrect credentials or discovers an error, it is important to display clear and concise error messages to guide them to take proper action.
    • Login Button- The login button appears beneath the email and password field. Hence, after entering the email and password, they can click on the button leading them to their concerned platform's homepage.

    Useful Tips to Keep in Mind While Writing Test Cases for Login Pages

    Test cases for login pages should cover all edge cases and possible scenarios which should encompass every functionality.

    A well-designed set of test cases promptly highlights the defects early in the development cycle leading to higher-quality software and user satisfaction. So, these are the following tips you must consider to create better test cases.

    • Defining Test Objective- Defining the objectives for creating test cases for login pages promotes testers to move ahead in the right direction. This step improves focus to determine what should be tested and how it can be done.
    • Identify the scenarios- Different scenarios that require to be tested which include system configurations, user inputs, edge cases, and preparing test data.
    • Write Test Cases- Create individual test cases for every scenario. It needs to be concise, clear and include information on the steps that need to be taken, preconditions, and expected outcomes.
    • Execute Test Cases- The next task is to execute test cases for login pages and record the results. Also, make notes of the defects or the issues which arise during testing.
    • Test Reporting- After executing test cases, the next step is to prepare a test report. Thus, the report must include a summary of the testing process, test results, along with the defects found during the test.
    • Review and Updating Test Cases- Regular review of the cases ensures that they are relevant and effective. Also, updating the test cases is necessary to reflect the change in the system or new testing requirements.
