JavaScript is one of the most common programming languages widely used by developers to create websites and web applications. It is a multi-paradigm language that allows you to select different approaches to programming, which, in turn, expands the functionality and scope of JavaScript.

The most important stage in the development of any software product is testing or Quality Assurance (QA). It is he who guarantees the appropriate level of software quality, correct and stable operation, as well as the absence of errors.

Choosing the right tools and developing a strategy, which is written in the plan, play a major role in testing. This document specifies the goals and objectives of the software product or site, approaches, resources needed and the priority of tests.

Regardless of what kind of product is developed using JavaScript, the following are subject to verification: its functionality, usability, security, interface, performance and compatibility.

QA specialists use the following types and methods of testing, which depend on the specifics of the resource:

Functional testing

At this stage, the functionality of the product, the operation of system processes, compliance with the specification, user interface, use cases, correct operation of all buttons, fields, etc. are subject to verification.

During testing, the task of specialists is to assess the capabilities and functions of the site / application, which must meet the customer’s requirements.

Depending on the purpose, the check can be carried out on the basis of:

  • functional requirements: for this, test cases are created, taking into account the priority of product features (which need to be tested).
  • business processes: in this case, the validation is based on the use cases of the system.

Usability testing

A type of testing software products that allows you to understand how convenient it is for use, whether the interface structure meets the business goals, whether the application or site makes the right impression on the target audience, which elements users pay attention to in the first place.

Usability testing includes checking:

  • conformity of product design to its functionality;
  • color design and graphic elements;
  • ease of navigation and link structure;
  • text filling and font design of content.

Performance testing

The challenge of testing is to determine the maximum load that a product can withstand. To make things easier, the Java Microbenchmark Harness (JMH) is a set of libraries for testing the performance of small functions. The stability of the application is tested, the capabilities in various configurations of the environment, the potential for scalability and the limit under peak load.

Compatibility testing

The test identifies compatibility of the product with server software, different operating systems and browsers, screen resolutions, client configurations, databases, and also determines the network bandwidth.

Website security testing

The site or application is necessarily tested for vulnerability to hacker attacks and the use of malicious utilities to ensure a high level of product security.

Due diligence allows you to analyze the risks associated with ensuring a holistic approach to software protection and unauthorized access to confidential data.

Besides the types of testing, there are two main types of tests: unit tests and integration tests.

  • Unit tests check the operation of individual components of a software product, for example, isolated functions, classes, etc. Experts use unittest and doctest for basic unit tests and pytest for high-level checks.

At this stage, testers try to understand whether the changes are causing problems in the already tested parts of the code, and also try to identify new defects. To simplify this task, a separate test is written for each function / method.

  • Integration tests, unlike unit tests, are used not to find errors in individual components, but to check processes and the system as a whole. It is for this reason that both types of testing are used together to help testers understand the big picture. The Continuous Integration System is usually used as an automation tool.

Also, experts often run end-to-end testing, the task of which is to check the product through the eyes of a potential user. E2E tests function as a black box and ignore the internal structure of the software.
