The end purpose of performing website testing is to make a user comfortable in learning, understanding, using and navigating the website, and thus includes almost all types of testing like:

  • Functionality testing for ensuring the intended and appropriate functionalities and features of a website.
  • Usability testing to ensure user-friendliness features of a website.
  • Compatibility testing looks after the compatibility of a website on multiple variants of browsers, OS, network, hardware, software, devices and many such elements, which are needed in the functioning of a website.
  • Performance testing ensures the smooth performance of a website both under the expected and undesirable load, conditions and environment.
  • Database testing concerns with the veracity, integrity, consistency, accuracy of the diverse range of data stored at backend of the website.
  • Security Testing ensures that no loopholes or security glitches left undetected in the website, which may grant access to unauthorized or malicious users to website and may victimize the website with other malicious attacks.

Each of the above stated testing types including some more types focuses and targets multiple aspects of a website. Thus, there is lot to test in a website and a tester may likely to miss one or more critical testing/elements which may need to be considered and tested. Here, we are listing out some of the essential elements in a checklist format, which are generally needs to be carried out to test a website.

1. Functionality Testing:

Following things are usually needs to be tested while performing functionality test of a website.

  • Forms testing: Forms on a website is used by the users to either store or retrieve information. Testing the form to ensure its consistency and integrity throughout the website. Further form testing may include following activities:
    • Validating each field of the form.
    • Validating each field with negative or invalid value.
    • To ensure default values for each field.
    • Highlighting the mandatory field with asterix * symbol.
    • Testing password field ability to conceal the entered password.
  • Link testing:Testing various links present or defined for a website and includes following types
    • External link: links which directs the website to any other web page or website outside its domain.

  • Verifying and validating the data integrity throughout the database in the event of addition, deletion and update of data.
  • Accurate retrieval of data against the injected query.
  • Testing tables along with the triggers, stored procedures, and views properties of a database.
  • Verifying all sorts of keys used in the database system.

3. Performance Testing:

In performance testing, certain specified parameters needs to be evaluated to assess the website performance under different conditions. Performance testing of a website generally consists of following:

  • Stability of the website under different load(in terms of users) and factors to work uninterruptedly without going into the state of failure or crash down, like
    • Normal load, full resource utilization.
    • Normal load with cut in resources.
    • Heavy load, full resource utilization.
    • Heavy load with cut in resources.
    • Extreme load with full access to resources.
    • Extreme load with limited access to resources.

    Here, resources may include usage of hardware, software (assisted application), server, memory (RAM), CPU, network speed and connection, space. Further, the above conditions may also include time criteria. Generally, load, stress, soak, spike and volume testing is being performed to ensure stability and reliability of the website.

  • Scalability of the website to accommodate the growing and changing requirements (load and resources).
  • Response time, throughput and speed of the website under different load and conditions as stated above.

4. Usability Testing:

If a user lacks interest in using and navigating a website, this directly impacts the traffic on the website. Thus, usability testing is essential QA activity to ensure user-friendliness feature of a website. In usability testing, following points may be taken into account:

  • Hacking & cracking the password.
  • Verifying the submission of confidential data and information through SSL certificates (HTTP).
  • Checking the SQL injection attacks on the website.
  • To ensure automatic termination of sessions in the event of non-activity of user for a considerable amount of time. Further, the logout user should not able to use session further.
  • Checking the unauthorized access to confidential data, information and web log files and repositories.

7. User Interface Testing:

A user interface mainly comprises three components- application, database server and web server. These three components are needed to be tested to ensure proper interfacing along with the accurate and appropriate flow of the data.


Above listed, is just a general checklist which commonly covers almost all sorts of website and important testing areas along with the corresponding testing methods. However, a tester may expand the list based on the specified requirements & specification, and the need felt by him/her, to carry out more in-depth and thorough testing of the website so that nothing gets missed out.
