What is website testing ?

Testing the site is the last and mandatory stage of the technical development of the site. It plays a crucial role in the process of resource creation because it is the quality of testing depends on the further life of the resource. Unfortunately, very often developers do not pay due attention to this stage, relying on their experience. As a result, existing errors lead to huge time and money wastes.

After all, a resource that has errors causes negativity among visitors and, consequently, their loss. As a result, the owner of the resource is forced to pay for revision (and sometimes for the re-development of the resource), and cooperation with former developers of the low-quality site leaves only an unpleasant precipitate.

Testing the site can take up to 50% of the time and budget. To understand where this figure came from, in this article we will tell you how the testing of websites to get a quality product at the output.


Objectives and basic methods of website testing

The purpose of the test is to check the actual functioning of the website for compliance with the requirements. The whole stage is a painstaking work of specialists, who in order to identify errors create artificial situations that may occur during the resource’s operation and analyze the “behavior” of the resource on the proposed conditions. After the detection of bugs (errors), the tester makes a report and passes it to the project manager, who distributes the work on their elimination among the project participants. After finalization, the resource is re-tested. This cycle of work is repeated until the website reaches the set results in the testing.

The website is tested for errors using different methods in different browsers. To achieve flawless functioning of the site, experts-testers create an action plan, which includes:

  • Testing of functionality;
  • Testing usability (ease of use);
  • Performance Test;
  • Security Testing;
  • UI Testing (interface testing).


Let’s take a closer look at each step.

Site Functional Testing

This is a crucial testing phase that cannot be replaced or skipped. Error in functionality will inevitably lead to a loss of clients. For example, if an error is made in the shopping cart function of an online store, then the visitor will not be able to buy a product, and due to an error in filling out the form of a page-lending, a single page will never move from zero conversion rate. Most often, the functional testing is checked:

Searching and placing an order, buying and paying for goods;
Form of registration or log in to your personal cabinet;
Opportunities to edit the site (adding items, editing content, etc.).

Testing usability

Testing the convenience of the resource should show how clear it is to the user how to find and order a product or service, whether the visitor is comfortable to be on the page, move between them, etc. Tester objectively assesses the project, identifying errors that may cause inconvenience, and as a consequence, to force a person to close the tab with the site. The usability testing site directly affects the visitor’s perception of the company. If he is uncomfortable to be on the page, he will never return to it.

Testing the load of the site

At this stage, the resource performance is analyzed and checked. It involves the technician understanding whether pages can handle a large number of users if they are doing something at the same time. The test is performed automatically, the maximum load on the resource is artificially created and the results are monitored.

User Interface Testing (UI Testing)

This type of testing involves checking if the GUI meets the requirements: whether it contains a uniform style, how professional it looks. At the same stage, it checks cross-browser availability (correct display of the site on all existing browsers regardless of version), adaptive version (if it is provided).

Site security testing

The quality of a resource’s safety depends on its reliability. The main purpose of this testing method is to identify vulnerabilities on the site during various attacks.


Testing a website – a process that affects the quality of resource performance, the impression of visitors about the company and, as a result, its benefits. This stage of site creation is a guarantee of peace of mind of the customer and the executor.
