Functional web testing is a type of web testing that focuses on testing the functionality of a website or web application. This includes testing to ensure that the various features and elements of the website or application work correctly and as intended. This can include testing for correct input validation, testing links and buttons to ensure they redirect correctly, testing forms to ensure they submit correctly, and testing for correct output of information. Functional web testing is often done by manually interacting with the website or application and by using automated tools to simulate user interactions.
There are several challenges that can be encountered when performing web testing:
- Browser compatibility: Websites and web applications must work correctly on a variety of web browsers, including different versions and configurations. Testing must be done to ensure compatibility across all targeted browsers.
- Device compatibility: Testing must be done to ensure that the website or web application works correctly on different devices such as smartphones, tablets, and laptops.
- Performance: Web applications must perform well under heavy loads and high traffic. Performance testing is done to identify and address any bottlenecks or other issues that can affect the performance of the website or application.
- Security: Websites and web applications are vulnerable to a wide range of security threats, such as SQL injection, cross-site scripting, and other attacks. Security testing must be done to identify and address any vulnerabilities.
- Constant change in the web technologies: With the rapid development of web technologies, it is challenging to keep up with the latest technologies, framework, and browsers. It can be difficult to ensure that the website or application is compatible with the latest technologies.
- Scaling: The website or web application must be able to handle a large number of users and increasing amounts of data. Scalability testing is done to ensure that the website or application can handle the expected number of users and data.
- Maintaining the test cases: Maintaining the test cases while the website or application is under development can be a challenge as the requirements and design can change frequently.
