Website Testing Full Procedural Guide

In a rapidly changing world, the Internet has become an inescapable source of information. Most of our business decisions are informed from the Internet, and we even make more and more purchases here. That’s why being present on the web is no longer an option. It’s a must-have item – no matter what industry they’re in.

If a company has a website, in most cases, it is still not enough to convince interested parties in a strong competition. You need to have a website that is fast, user friendly and, most importantly, informative. For the website to do the best it can in these areas, thorough testing is required. The following article is about these testing procedures.

What is website testing?

Website testing is a total of procedures designed to detect potential errors and, in many cases, to propose improvements. The purpose of testing is to systematically touch any area that may cause an error on a website or even any web software. Depending on the nature and severity of the error, we may lose visitors, potential customers, in more severe cases, cause immediate loss of revenue or adversely affect the perception of the whole company.

With a properly tested test, your business can make sure that your website is flawless and ready for production.

Who’s testing?

Unfortunately, in most cases, the web developer who worked on the website is testing. However, the ideal scenario is for testing to be carried out by another developer or, rather, by an external person, as this will eliminate bias against your own work.

For more serious web development projects, both budget and development time are calculated for testing by an external team and correcting errors, depending on the results.

Parts of the website testing

Website testing consists of the following parts:

  1. Functional testing
  2. Usability testing
  3. Test user interfaces
  4. Compatibility testing
  5. Performance testing
  6. Safety testing

1. Functional testing

Functional testing is designed to verify that all website or web application components work to the specifications. This, of course, requires an existing and sufficiently thorough specification.

Functional testing covers the following areas:

Check links

  • External links
  • Sitelinks
  • Email links
  • Broken links
  • Orphan sites

Test forms

Forms are a key part of a website because they are usually used to connect with the company. Therefore, their testing is of the utmost importance. The following parts are checked:

  • Error signals
  • Error messages
  • Field validation
  • Fields to be filled in
  • Field masking
  • How password fields work
  • Captcha operation

Cookie testing

The emergence of GDRP has also increased awareness of cookie use and tightened its use. Of course, compliance with GDRP recommendations is also a focus when testing cookies.

  • Cookie popup
  • Privacy Policy and Cookie Policy
  • Website operation with cookies turned on and off
  • Cookie encryption
  • Cookie Expiration

HTML and CSS validation

This section checks that the HTML and CSS encoding of the web page meets official standards.

  • HTML and CSS syntax checks
  • Website crawl
  • Existence of XML sitemap

2. Usability Testing

Usability testing checks how easy the site is for your audience.

The most important parts to test are:

navigation

Is the website’s navigation consistent, easy to use, the name of the menu items can be achieved, their grouping follows the correct logic?

content

  • Is the content of the website logically structured and its language easily accessible to the target audience? Is there no spelling errors or typo in the content? Is the text high-contrast, easy to read?
  • Do the quality and resolution of the images in the content meet your expectations?
  • Is there a search engine on the website? Is it logical and easy to use?

3. User interface testing

The user interface is the element of the site through which the visitor interacts with the website. If the user interface is uneven, confusing, difficult to see, visitors click away from the page. Testing is therefore critical to success.

When testing user interfaces, we examine the following areas:

  • Check compliance with user interface standards
  • Control design elements: layout, colours, fonts, captions, text blocks, text formatting, pushbuttons, CTA’ s, icons, links
  • Test the surface at different resolutions
  • Test language versions
  • Testing on different devices (mobile, tablet, desktop)

4. Compatibility testing

We use the Internet from a variety of different types of devices with operating systems and browsers. Your website must work flawlessly on all of them, whether it’s a smart TV, mobile, or desktop.

During compatibility, we look at the following areas:

  • Browser compatibility
  • Operating system compatibility
  • Mobile compatibility
  • Printing options

5. Performance testing

Performance testing is designed to check how your website and the host environment behind it perform under traffic load. In the case of webshops and high-visibility portals, it is of the utmost importance that they are stable even in extreme cases. Performance testing examines the following areas:

Stress test

The stress test measures the stability and reliability of the software under extreme loads. The stress test checks the robustness of the system. During the test, the system is put under a large amount of sudden load and is measured to see if it collapses, how it recovers.

Load test

The load test measures the upper limit of system operation and how it performs under heavy load. An example of a load test is to measure a word processing software when editing a large document (e.g. thousands of pages).

Stability test

In the case of a stability test, the long-term operation of the software is measured under everyday operating conditions. The test aims to find out if the software is not an omen, how it handles operational errors.

Volume test During

the volume test, the performance of the software and the time of response are measured over a large amount of data. During the test, the amount of data received in the database is continuously increased while measuring response time and possible data loss.

6. Safety testing

In the end, I left perhaps one of the hardest areas. The diversity of attacks from the Web and the vulnerability of content management systems have presented new challenges for web developers in recent years. A website that is vulnerable to security risks the company’s image and can also compromise the often sensitive personal data stored on it.

Therefore, in many cases, separate teams of experts are invited for safety testing, and the method is also called ethical hacking.

Areas of security testing include:

  • Existence of SSL encryption
  • protecting forms
  • Session treatment
  • logging
  • protect password-protected interfaces
  • encrypting and protecting sensitive data
  • protecting the content management system
  • virus protection

Summary

As my article shows, testing web pages and web applications is a very multifaceted task that should not be left to the web developer himself. Unfortunately, in most cases, due to the low budget or short deadline for web development projects, this area receives little attention. It is only dealt with when the problem has already occurred. My article tries to help those who want to get started and run their website without errors in the long run.
