Functional or Black Box Testing of Web Applications

Functional or Black Box Testing of Web Applications

Web Browser-Page Testing:
This type of test covers the objects and code that executes within the browser, but does not execute the server-based components. For example, JavaScript and VB Script code within HTML that does rollovers, and other special effects. This type of test also includes field validations that are done at the HTML level. Additionally, browser-page tests include Java applets that implement screen functionality or graphical output.

For web browser testing we can create test cases using following guidelines:

1)

If all mandatory fields on the form are not filled then it will display a message on pressing a submit button.

2) It will not show the complete information about sensitive data like full credit card number, social security number (SSN) etc.

3) Hidden passwords.

4) Login by the user is must for accessing the sensitive information.

5) It should check the limits of all the fields given in the form.

Transaction Testing:
In this testing, test cases are designed to confirm that information entered by the user at the web page level makes it to the database, in the proper way, and that when database calls are made from the web page, the proper data is returned to the user.
Conclusion:
For trouble-free operation of a website we must follow both non-functional and functional testing methods. With these methods one can test the performance, security, reliability, user interfaces etc. which are the critical issues related to any website.
