How To Perform Website Testing?
- Define Test requirements - Identify the core functionalities, user journeys, devices, and browsers to be tested. Align testing goals with business and user expectations.
- Test Planning - Create a test plan outlining scope, objectives, types of testing, timelines, and responsibilities. Prepare test cases and data based on requirements.
- Types of Website Testing - Perform different types of testing based on priority. Ensure proper security testing is also performed, as websites are susceptible to vulnerabilities and threats.
- Automation Testing - Select the tests that can be automated like regression testing and other repetitive tests to improve test coverage.
- Set Up Test Environment - Prepare a staging environment that replicates production. Ensure all integrations, databases, and configurations are ready for testing.
- Final Review - Conduct User Acceptance Testing (UAT) to validate from an end-user perspective. Review, fix any bugs, and ensure readiness before launch.
Points To Consider While Testing A Website
Website UI & Layout
Pay special attention to verifying the UI, layout, and content on the website application.
- Test the UI specifications as per the UI deck requirement document.
- The size of buttons, menus, and text fields should be properly aligned with other controls as per the height and width of the page.
General Validations
General validations are performed considering the overall architecture of the software.
- Module-wise, ensure to test all the functionalities of a web application. Test the web forms at all the steps, right from filling the form to verifying until the confirmation page.
- Verify that the fonts and images used in the application are uniform across all browsers.
- Verify that the fields that are by default to be kept disabled are not clickable.
- On the login page, verify that the cursor points to the username text field as an indicator to input details in this field.
- Test the working of scroll bars and popups on the web page.
- Test if there′s any broken links on the web page application.
- Focus on properly testing the fields like dropdowns, check boxes, list boxes, text boxes, etc.
- Verify if the values in the dropdown list are present in alphabetical order.
- In the case of a text box, test that the fields are marked with a (*) mandatory indicator, which will help users understand this better.
Database Validations
Databases form the backbone of web applications. Hence, they are essentially important as an application′s front-end requests are processed by fetching results from the database.
- The database should be validated to check the password encryptions.
- Verify that a column does not allow a “NULL” value until any such condition is specified.
- Test if the data is stored in the correct format in the database.
- Test the time taken for a stored procedure to execute a command.
Security Validations
Security validations are done to identify security loopholes in software and the key areas that are prone to security breaches.
- Validate sensitive data does not appear in the URL
- Test all web application data transmitted over the web using ′′shttps′′, for example, payment information, passwords, etc.
- After the session timeout of an application, the same user should be prompted to log in again.
- Monitor denial of service attacks.
What Are the Challenges Faced During Website Testing?
- Browser Compatibility - It is important to ensure that your website is compatible with different browsers like Chrome, Mozilla, Edge, etc.
- Responsiveness - The website should be responsive in different devices, adhering to the devices screen sizes, resolutions, etc. Testing in different types of devices either physically or virtually via a simulator/emulator can be challenging.
- Dynamic and Asynchronous content - Modern websites often use AJAX or dynamic content loading (e.g., infinite scroll), making it harder to validate elements that don′t load immediately.
- Security - Testing webpages should include testing for critical vulnerabilities like SQL injection, CSRF, XSS, and other exploits.
- Scalability - One of the biggest challenges in maintaining a website is scalability. With heavy traffic, the website becomes less stable. It is mandatory to ensure that load and performance testing are performed by simulating such conditions.
