Conducting Web Testing (part 1: Functionality Testing)


There are six types of website testing, and in this notes, I will be focusing first on Functional Testing.

So what is Functionality Testing?

Basically, this is when QA checks if the website functions correctly according to the set list of requirements. Let’s list down the things you need to check when doing Functionality Testing:

  1. Links  - check the following if these are behaving accordingly and that there are no dead links.
    • Internal links. This includes your navigation, other links that will point the user to other pages inside your website. You can find these at the header, sidebars, footer and in the content in some pages.
    • Mailto: links or the links which when clicked will open the email client with preset recipient and allows the users to compose their email.
    • Links that are pointed other websites which most of the times will open new tabs.

  1. Forms our users use to submit information to our site. The following should be checked:
    • How the inputs are being validated.
    • The default values of each input field
    • How the fields behave to invalid input
    • Any options to modify the forms

  1. Cookies where the user data is temporarily stored in the user’s computer. It contains login sessions and other user activity-related data.
    • Check how the site behaves with enabled and disabled cookies in your browser options
    • Check if the cookies are encrypted
    • Check for login sessions after the cookie expired
    • Try to delete the cookie manually then check how the website will behave

  1. Validate HTML/CSS
    • Check for any HTML syntax error. There are online tools which can help like https://validator.w3.org/
    • Check if your site can be indexed by Search Engines
    • You can also verify if you have accurate site map in XML and HTML format

  1. Data Integrity - do database related activities to check for consistency of the data retrieved from and sent to the database. Check if there are any errors in displaying the data.

There are tools you can use to do Functionality testing. Below are some of the suggestions:

  1. Selenium - for open source enthusiasts. This functionality testing tool is well known with many active users/ organizations
  2. Telerik Test Studio
  3. CUITE - a tool by Microsoft which is now moved to Github
