checklist of Web application testing:

checklist of Web application testing:

1) Functional Testing (Regression, Integration, Smoke Testing)
2) Browser Compatibility Testing
3) Performance Testing
4) Security Testing
5) Production Monitoring
6) Usability Testing


Check links:
Test links to a page from external pages
Test all links on a page for correct operation
Test links to anchors on the same page
Test email mail-to linksIdentify orphan pages - pages that are not linked from other pages


Test Web forms on the page:
Check the field validation logic for each fieldCheck default values for each field
Check that password fields do not show the password contents
Negative test invalid input values for each field
Validate the response to a form submit

Session and Cookie Management Testing:
Check application log-in sessions by enabling and disabling cookies
Negative test cookies by using a mismatching domain
Check that session cookies reset between browser sessions
Check application security by selectively deleting cookies while a test operates

Validate Cascading Style Sheet (CSS) tags:
Identify CSS tags that return 404 or other CSS load errors
Identify HTML id, class, and name attributes that do not match any CSS tags
Validate JavaScript tags:
Identify Script tags that return 404 or other load errors
Identify id, name, on... attributes that do not match any Script tag
Dynamic content testing (aka Database testing):
Check data consistency in database-driven Web forms
Check create, edit, delete, update (CRUD) tasks
Verify data retrieval delivers the correct data
Identify database connectivity and query errors


2) Browser Compatibility Testing:
Differences in Web browsers, operating environments, and hardware devices impact the correct operation of your Web application.
Browser compatibility:

Test your Web application for correct function on several browsers, including Firefox, IE, Chrome, Opera, and Safari. Ideally your Web application handles browser differences elegantly.
Check application function with a variety of browser security profile settings
Verify application function with browser features turned-off (JavaScript, Cookies)
Check browser rendering of your application's user interface
Check the browser's security settings for cross domain access and hacks
Verify consistent application function across multiple versions of a browser
Operating Environment Compatibility:
Check application user interface rendering on OS windowing systems
Check desktop integration functions, including drag-and-drop and file selection
Test your web application on different operating systems, including Windows, Unix, MAC, Linux, and Solaris
Mobile Device Compatibility:
Check application compatibility with device services, including location and dialing services
Check user interface rendering on mobile device screen sizes, including screen rotation


3) Performance Testing:

Web Load Testing
Linear scalability - where an application's performance does not vary as the number of users increases - is the Holy Grail of Web application testing. Load testing identifies a Scalability Index for your Web application performance.
Check server response to browser form submit requests
Identify performance changes over a period of time
Test for functions that stop working at higher levels of user load
Identify the network latency problems on Web application function

Web Stress Testing

Determine how the application responds under high levels of load
Identify portions of the Web application that fail under high levels of load
Identify application function after a system crash or component failure
Identify forms and links that operate differently under high levels of load
Verify correct application operation when device is in and out of range of network services


4) Security Testing:
Protect Web application data and maintain functionality as designed.
Check URLs for operation without loging
Test basic authentication using false user name and password credentials
Check X.509 security certificates on secure Web pages
Test for correct application function upon invalid URL attribute values
Check for application function with invalid input fields, including text fields
Check for Web server protection of inaccessible Web directories or files
Check for Web application identification of security breaches, including error messages and security breach attempts being logged
Test CAPTCHA fields for Web forms and logins
Test browser security settings for moving from secure to insecure pages


5) Production Monitoring
Operate the Web application tests periodically and save the test logs as proof of Servlice Level Agreement (SLA) compliance
Periodically check the end user experience
Provide auto-scaling and load balance systems with end user experience metrics
Check for correct application function from a variety of geographic locations

6) Usability Testing
The design and presentation of an application has a large impact on the success your users will have in using the Web application.
Check for the user to have apparent and easy controls to move from page to page.
Test the flow of a Web application by observing how the user accomplishes their goals
Check that the user can find instructions should they not intuitively know how to operate a function
Test that common navigation objects appear on every page consistently
Test search functions for proper application functions
Content Checking:
Test that content is logically arranged and easy for users to understand
Check for spelling errors
Check that pages adhear to color and pattern style guidelines, including fonts, frames, and borders
Check that images load correctly and with proper sizes
