Test for - all the links in web pages, database connection, forms used in the web pages for submitting or getting information from user, Cookie testing.
Cookies are small files stored on user machine. These are basically used to maintain the session mainly login sessions. Test the application by enabling or disabling the cookies in your browser options. Test if the cookies are encrypted before writing to user machine. If you are testing the session cookies (i.e. cookies expire after the sessions ends) check for login sessions and user stats after session end. Check effect on application security by deleting the cookies.
Validate your HTML/CSS:
If you are optimizing your site for Search engines then HTML/CSS validation is very important. Mainly validate the site for HTML syntax errors.
Data consistency is very important in web application. Check for data integrity and errors while you edit, delete, modify the forms or do any DB related functionality. Check if all the database queries are executing correctly, data is retrieved correctly and also updated correctly. More on database testing could be load on DB, we will address this in web load or performance testing below.
2) Usability Testing:
Test for navigation:
Navigation means how the user surfs the web pages, different controls like buttons, boxes or how user using the links on the pages to surf different pages.Usability testing includes:
Web site should be easy to use. Instructions should be provided clearly. Check if the provided instructions are correct means whether they satisfy purpose. Main menu should be provided on each page. It should be
Content should be logical and easy to understand. Check for spelling errors. Use of dark colors annoys users and should not be used in site theme. You can follow some standards that are used for web page and content building. These are common accepted standards like as I mentioned above about
annoying colors, fonts, frames etc.Content should be meaningful. All the anchor text links should be working properly. Images should be placed properly with proper sizes. These are some basic standards that should be followed in web development. Your task is to validate all for UI testing
3) Interface Testing:
The main interfaces are:
Web server and application server interface
Application server and Database server interface.
Check if all the interactions between these servers are executed properly. Errors are handled properly. If database or web server returns any error message for any query by application server then application server should catch and display these error messages appropriately to users. Check what happens if user interrupts any transaction in-between. Check what happens if connection to web server is reset in
4) Compatibility Testing:
Compatibility of your web site is very important testing aspect. See which compatibility test to be executed:
Operating system compatibility
5) Performance testing:
Web application should sustain to heavy load. Web performance testing should include:
Web Load Testing
Web Stress Testing
Test application performance on different internet connection speed. In web load testing test if many users are accessing or requesting the same page.Site should handle many simultaneous user requests,large input data from users, Simultaneous connection to DB, heavy load on specific pages etc.
6) Security Testing:
Following are some test cases for web security testing:
Test by pasting internal URL directly into browser address bar without login. Internal pages should not open.
If you are logged in using username and password and browsing internal pages then try changing URL options directly. I.e. If you are checking some publisher site statistics with publisher site ID= 123. Try directly changing the URL site ID parameter to different site ID which is not related to logged in user. Access should denied for this user to view others stats.
