How to Write Test Cases for Login Page

Learn to write exam cases for login page covering scenarios like performance, protection, Gmail login, and more to ensure thorough testing.Test cases for a login page are predefined scenarios created to check that the login functionality of an application performs aright. These cases assess respective aspects, including successful and failed login endeavor, user interface behavior, etc. under different load conditions.

This guidebook will walk you through how to write trial cases for login pages, ensure that all critical areas are covered.

What are Test Cases for the Login Page?

Test instance for a login page are specific conditions or scenarios designed to corroborate that an application & # 8217; s login functionality works as expected. These trial cause continue different panorama, such as valid/invalid login attempts, UI deportment, security assay, fault manipulation, performance under load, etc. They help ensure exploiter can log in securely, without issues across diverse environments.

Types of Test Cases for Login Page

Here are the main types of exam lawsuit that would be require for a login page:

• Case: Verifies the right functioning of the login procedure with valid and invalid stimulant.
• Case: Verifies non-functional aspects like the system performance, usability, or reliableness, etc., under specific conditions, such as response time, scalability, or protection.
• Case: Ensures the login page layout, plan, and elements for its visual consistency and correctness.
• Security Test Case: Checks for vulnerabilities like SQL injection, password security, and untroubled access.
• Negative Test Case: Validates system behavior when incorrect or unexpected input is given.
• Case: Measures the login page & # 8217; s performance under different load and stress weather.

Characteristics and Components of a Login Page

Before diving into the test cause, it ’ s indispensable to understand the components of a typical login page. A standard login page consists of:

• Username/Email Input Field:Where users input their credentials.
• Password Input Field:A secure field that masks the user ’ s password.

Each component needs to be prove meticulously to ensure they act as intended under all circumstances.

Functional Test Cases for Login Page

Functional exam cases verify that all the elements of the login page work as expected. These are widely categorise into positive and negative scenarios.

Positive Test Cases

The undermentioned positive test cases corroborate the system & # 8217; s ability to authenticate users effectively through standard login method.

• Valid Login with Correct Credentials:Enter a valid username and password and snap the login button. The exploiter should be successfully logged in and so be redirected to the dashboard.
• Case Sensitivity of Username and Password:Test the login with different cases (uppercase/lowercase) for the username and watchword. Login should merely follow if the precise suit is habituate.

• Login with Vacuous Fields:Try to log in without entering any credentials. The system should remind the user to occupy in the required fields.
• Login with SQL Injection:Attempt to log in by enrol an SQL query in the username or password field to manipulate the database query executed by the application. The system should reject the input and not fulfil the SQL enquiry.
• Locked Account After Multiple Failed Attempts:Enter wrong credential multiple time to try account locking mechanism. After a set number of failed attempts, the account should be operate, and the user should obtain a apprisal.

Non-Functional Test Cases for Login Page

Non-functional test cases judge aspects like protection, performance, and usability, insure the login page is functional but also secure, efficient, and user-friendly.

Security Test Cases

• SQL Injection Prevention:Attempt to log in using SQL dictation in the input fields. The scheme should sanitize inputs and prevent SQL performance.
• Cross-Site Scripting (XSS) Testing:Enter JavaScript code in the username or password fields to quiz for XSS vulnerabilities. The scheme should not execute the script, and it should escape special fibre.
• Password Encryption:Ensure that passwords are encrypted in transit and at rest. Passwords should not be transmitted or store in champaign text.

Usability Test Cases

• Intuitive Design:Evaluate the design and layout of the login page to assure it & # 8217; s user-friendly. Users should find the login page easily, with clear instructions and accessible options.

3. Test if participate a single quote (& # 8216;) or double quote (& # 8220;) in the username or password field triggers an fault (e.g., syntax errors) in the application. Example input: & # 8216; OR 1=1–
4. After submitting the freight, check if any database fault messages are displayed. These messages can expose vulnerabilities.
5. Test if participate a warhead like & # 8216; OR 1=1 & # 8212; bypasses the login process and grants unauthorized accession. A successful SQL injection should log you in without valid credentials.
6. Test more advanced SQL injectant variants like UNION-based injection, time-based blind SQL injection, or error-based injection. Example: & # 8216; UNION SELECT null, username, password FROM exploiter –
7. Check if the scheme implements any security mechanisms, such as account lockout after multiple failed login attempts, to foreclose SQL injection abuse.
8. Verify that the system sanitizes stimulus properly by decline invalid or malicious input.
