We'd like to talk about what stages the site goes through before going into production.

Testing is the deviation of the actual result from the expected result, in other words, it's the process of searching for bugs.

The basic rules for testing websites are steps that show the user how easy and logical the project will be, how easy and possible to find this or that information. Whether well perceived by the human eye and whether the entire functionality of this site works correctly, which was delivered according to the TOR or the brief is the main indicators for the tester.

How to test the website?

Testing can occur in a variety of ways, but don't forget about the process itself and the testing strategy. The sequence of your actions depends on it. To date, experts in testing websites use such types as:

  • Functional testing

  • Usability testing

  • Load testing

  • UI testing

  • Security testing

Let's consider these types of testing in more detail:

Functional testing

One of the important and irreplaceable kinds of testing. The most important rule of functional testing is the correct calculation of functions. For example, take an online store that has not only discounts on the goods, but also a lot of statuses when buying, number of products. All of these options should be taken into account. After all, if the project functionality doesn't work in a specific browser, then it won't work anywhere. If you take a certain functionality for web projects, then basically checked:

  • search and purchase of goods, ordering

  • navigation

  • form authentication

  • add, delete, edit, order, etc

Usability testing

Usability testing is a type of testing that makes the website convenient and practical to use. The main goal is to show the user:

  • Is your website understandable and convenient?

  • Convenient navigation?

  • What is the impression of the user?

  • What can be superfluous or unnecessary?

Load testing

Performance testing is basically a load testing. Load testing of the site is checked in most cases automatically by special programs. It gives a chance to check how much it'll work under a certain load.

The purpose of this test is to count the number of virtual users who specify number of requests at one time (be it seconds even). Thus, the result is whether our project was able to withstand, for example, 100 users who simultaneously bought the goods or were authorized on the site, the answer shows whether it is really possible to sustain the site such a load.

UI testing

UI testing is testing of the graphical user interface, which involves checking the site for compliance with the requirements for the graphical interface, whether it looks professional, whether it is performed in a unified style.

In most cases, user interface testing is performed with the following types of testing (UI):

  • Testing for compliance with the standards of graphical interfaces

  • Testing with different screen resolutions

  • Testing cross-browser compatibility, or compatibility with different Internet browsers and their versions

  • Testing of localized versions: accuracy of translation (multilanguage, multicurrency), checking the length of names of interface elements, etc.

  • Testing the graphical user interface on target devices (smartphones, PDAs, tablets).

Testing a site for vulnerabilities

This's the key to the reliability of websites. The basic rules of this testing are checking for the vulnerability of different types of attacks. If this is an online store, then, most likely, you should check the SQL injection requests (database queries).

SQL injection is malicious code in database queries. It's the most dangerous type of attack.

Here is, perhaps, the main types that are used to test the site.
