Important Website Testing Checklist

Let’s start with the Website Web Application Testing Checklist: Testing a website thoroughly is crucial to ensure its functionality, usability, and overall user experience. However, website testing can be a complex process with many different aspects. This is where a website testing checklist comes in handy.

A website testing checklist is a comprehensive list of items that must be tested before launching a website. It covers all aspects of website testing, including functionality, usability, performance, security, and cross-browser compatibility. Using a website testing checklist, website testers can ensure that they don’t miss any critical elements in the website testing process, and developers can ensure that their website meets all the necessary standards to ensure a high-quality user experience.

In this article, we’ll explore the benefits of using a website testing checklist, the items that should be included, and how to implement a website testing checklist in your testing process.

When we start the testing process for a website, we perform the below testing on a website:

  • Functionality Testing
  • Performance Testing
  • Web Usability Testing
  • Compatibility Testing
  • Web Security Testing

For More Details, Check Below:

Functional Testing

The following testing must be carried out while doing Website Functionality testing:

Validation Testing

  • You should make sure that valid HTML is used for your website. To check this, you can use the W3C validator.
  • In functionality testing, the different fields used on the website should be validated, like Textboxes, dropdowns, radio options, checkboxes, Combo box inputs, links, etc.
  • Nowadays, most websites prefer CSS, which means Cascading Style Sheets. Many CSS validator tools are available; one of the good tools is the W3C CSS validator, which will help you validate the CSS used in your site user test.

Links/URL Testing

This testing is very much interesting and can be helpful for SEO on your page. The following types of testing should be carried out for Link or URL testing:

  • Internal links: The link pointing to the same websites’ pages. This testing ensures that the internal links are properly linked to the expected pages of your website’s links like Homepage, Contact Us, About Us, etc.
  • External links: The link pointing to the pages of external websites. This testing ensures that the internal links are properly linked to the expected pages of external sites.
  • Email links: Such links must ensure that if a user clicks on the link, the default email client should open with the To address pre-filled.
  • Broken links: Broken links are also called Dead links. Such links are not linked to the website’s internal or external pages. Such a link generated with spelling mistakes in the link URL or linked page is removed, or no more exists. To check the broken link, you can use online tools to validate the broken links on the website.

WebForms Testing

In the Website Testing Checklist, the web forms are the most commonly used in the websites, so it is one of the most important parts of website testing. Consider a scenario where a user fills out an inquiry form and clicks on the Submit button; now what next, or do they fill in the form and do nothing? The details do not get captured correctly and so are lost. While doing forms, functional testing ensures they are consistent and contain the required input and output controls. The data should be appropriately captured.

Database Testing

Nowadays, with new technologies like Android and smartphones, computer applications are more complex.

If the front end is more complicated, the backends are also convoluted. As a result, it introduces a more complex database schema to support such intricate computer applications. So it’s more important to validate the databases to ensure the quality and website can handle the data processing efficiently.

Cookies Testing

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

Testing of Error Messages

In a well-developed website, the error messages are very helpful in guiding users to success and erroneous conditions while navigating through the application; if poorly designed, error messages will easily misguide the end-users. Many websites use different interesting pages when a 404 error is displayed.

Required field and optional field validation

The required and optional fields should be handled efficiently. Ideally, the application should not be submitted until all required fields are correctly filled. The required error message should be displayed when the user proceeds with not filling in the mandatory fields. It should not restrict you from proceeding further if the optional fields are not filled.

Client-side Testing

This type of testing is a subset of Security testing. This testing must check if the sensitive modafinil online sale data is not stored in temporary internet files or an encrypted format like passwords, credit card information, bank numbers, etc.

Performance Testing

Software Performance testing is a type of testing performed to determine the system’s performance to major measure, validate, or verify quality attributes of the system like responsiveness, Speed, Scalability, and Stability under various load conditions. 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 can sustain. Performance testing is used to understand the scalability of an application under test. Response time means the time required to send a request from the client machine to the time required to reply by the server under various load conditions that mimic real-world use.

Performance testing can be applied to understand the website’s scalability and 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 can sustain.

Web Usability Testing

The Usability Testing comes from a Black Box Testing Technique where testing is to be carried out from the user’s point of view. It is a technique implemented in user-centered interaction design to evaluate a product or service by testing it with representative users. On the Web page, usability is the most important and required condition for survival.

People will not stay on the page if the website is difficult to use. Also, if the content or details of the page are difficult to read or understand, people will not stay on the page. So, Usability testing is important in assessing how easy user interfaces are to use.

Usability testing is categorized into Accessibility, Identity, Navigation, and Content. You should keep in mind a few points while testing a web application for Usability testing:

Accessibility: (Add Bullets)

  • Site Load Time should be reasonable.
  • Site font size and spacing between lines should be easy to read.
  • Carefully use Flash and add-ons on a website.
  • Proper ALT Tags should be used for all images present on the website.
  • If an internal link is broken, the website should have a 404 error page or a Not Found page.


  • The website logo should be prominently placed on the top right side of the page.
  • The Proper tagline should be used, clearly stating the website’s purpose.
  • Company and Contact Information must be mentioned, which helps to identify the company information.


  • Main Navigation should be easy to find, read, and use. If more than navigations are used, the user should clearly understand why multiple navigations are used.
  • Clear and concise navigation labels should be used on the website.
  • Use links and buttons on the website reasonably so users will not be confused while navigating the pages.
  • The Company Logo should be linked to the website Homepage as a common practice.
  • The Site Search facility should be present on the website, and make sure that the Site Search button is simple and easy to access, like the top right of the page.


  • Headings should be clear and descriptive, and SEO use proper heading tags like H1, H2, etc.
  • Ensure the critical content is displayed on the first screen in average screen resolution, i.e., 1024×768.
  • Using consistent font styles and colors across the website helps users understand they’re still on your site.
  • Using user-friendly and meaningful keywords for URLs will help users and search engines understand navigation.
  • Meaningful and self-explanatory titles (in the <TITLE> tag) should be used for pages. Search engines use these titles to display in the search results if improper titles are used when a user will skip your website pages, link, and proceed further.

Compatibility Testing

  • In the Website Testing Checklist, the Compatibility Testing ensures that the web pages properly render different browsers like IE8, IE9, IE10, IE11, Chrome, Firefox, Safari, Opera, etc. Also, verify if it works properly on different Operating systems like Windows XP, Windows 7, Vista, Linux, Mac, etc., on various hardware configurations.
  • The most typical compatibility tests should be considered while testing your application:» Check on different browsers and their versions.» Check on different Operating systems and their versions.
    » Check on different hardware configurations
    » Check on different network environments.
    » Check on different screen resolutions.

Web Security Testing

Security testing is one of the most important types of software testing that ensures the vulnerabilities or weaknesses of the software application. The main objective of security testing is to find the vulnerabilities of the system & determine that its data and resources are protected from possible intruders. Security testing allows us to identify whether confidential data stays confidential or not. This type of testing is also known as Penetration Testing.

Some of the major aspects of web security testing are:

  • Penetration Testing
  • Password cracking
  • Vulnerability
  • URL manipulation
  • SQL injection
  • Cross-Site Scripting (XSS)
