B) Links/URL Testing:

This testing is very much interesting and can be helpful for SEO of you r page. Following types of testing should be carried out for Link or URL testing:

  • Internal links: The link which are pointing to the pages of same websites. This testing make sure that the internal links are properly linked to expected pages of your websites link like Home page, Contact Us, About Us etc.
  • External links: The link which are pointing to the pages of external websites. This testing makes sure that the internal links are properly linked to expected pages of external websites.
  • Email links: Such link need to make sure that the if user clicks on the email link then default email client should open with To address should be pre-filled.
  • Broken links: Broken links are also called as Dead links. Such links are not linked to any of the pages either internal or external pages of the website. Such link generated with the spelling mistakes in the link URL or linked page is removed or no more exists. To check broken link you can use online tools to validate the broken links in the website.


C) Web Forms Testing:

In Website Testing Checklist the web forms are the most commonly used in the websites, so it is one of the most important part of the website testing. Consider a scenario where user fills an enquiry form and click on Submit button, now what next or they just fill in the form and do nothing, the details do not get captured correctly and so are lost. While doing forms functional testing make sure that they should be consistent and should contain the required input and output controls. The data should be captured properly.


D) Database Testing:

Now days with the new technologies like android and smart phones computer applications are more complex.

If the front end is more complicated then the back ends are also convoluted. As a result, introduce more complex database schema to support such intricate computer applications. So it’s more important to validate the databases to make sure the quality and website able to handle the data processing effectively.


E) Cookies Testing:

A Cookie is information stored in text file on user’s hard drive (client side) by web server. This information is used later by web browser while accessing the website. Ideally the cookie is used to store the personalized user information or data in encrypted or secured manner. This is small size files which act as unique identifiers and allow websites to remember a particular user for a given time. These files are not harmful for users. Sometimes if the user’s personal information is stored in the cookie and if hackers stolen the cookie then hacker can get the confidential information which leads to security issues. That’s why the testing of Cookie is most important. There are two types of cookies Persistent Cookie and Non-Persistent Cookie.


F) Testing of Error Messages:

In the well developed website the error messages are very much helpful to guide users for success and erroneous conditions. While navigating through application if poorly designed error messages will easily misguide the end users. Many of the websites are used different interesting pages when 404 error is displayed.


G) Required field and optional field validation:

The proper handling of required and optional fields should be efficiently handled. Ideally the application should not be submitted unless and until all required fields are filled properly. The required error message should be displayed when user proceed with not filling the mandatory fields. It should not restrict you for proceeding further if the optional fields are not filled.


H) Client-side Testing:This type of testing is subset of Security testing. In this testing need to check if the sensitive data is not stored in the temporary internet files or stored in encrypted format like passwords, credit card information, bank number etc.

The main aim of Performance testing is not to find the defects in the application but to get rid of bottlenecks and find out the amount of load/stress the site is able to sustain. Performance testing is used to understand the scalability of application under test, response time means time required to send request from client machine to time required to reply by the server under different varity of load conditions which mimic the real world use.

Performance testing can be applied to understand the website’s scalability, any loopholes in the load balancing and to test the response time between a request (from the client) and the reply (from the server) and the amount of load/stress the site is able to sustain.
