TESTING WEB APPLICATIONS

The range of use of web applications is very wide, and the set of their functions is diverse, while they should work correctly on different mobile devices, in browsers and operating systems. In order to ensure a positive user experience, the developers conduct tests taking into account all possible scenarios and combinations.

Testing is an integral part of the software life cycle, which guarantees its reliability and high quality.

The main task of testing is to check the functionality of the application and search for possible problems, since any software must work in accordance with certain criteria, fulfill its purpose and meet the client’s requirements.

The following are subject to testing: functionality, usability, security, compatibility, as well as software performance.

In order to simplify the verification process and save time, web application test automation tools are often used:

• Selenium is a flexible framework for testing software in various browsers and platforms that allows you to create complex scripts.

• Watir is a tool for testing language web applications, cross-browser testing and validation of buttons, forms, links on web pages.
• TestStudio is an automation tool for testing desktop and mobile applications, user interface, load and performance.
• TestComplete is a tool that experts use to conduct data-driven keyword testing.

When choosing frameworks and automation tools, the peculiarities of one or another type of web application testing are always taken into account. This approach to product verification gives the company a significant advantage in today’s competitive environment.

In software engineering, the following web testing methods and techniques can be applied, which depend on the functions, purpose of the product and the client’s requirements:

• Functional testing

Functional testing is a process that includes checking the basic elements of an application: user interface, API, database, security level, as well as server performance and other parameters. It runs as follows:

• using pre-developed test scenarios;
• by exploratory testing.

Also, attention is paid to the correct operation of internal, external, anchor links and mailto links, forms, cookies, usage scenarios are checked.

• Usability testing

This type of testing allows you to figure out whether the structure of the interface meets the business goals, whether the product makes the right impression on the target audience, what elements of the application users pay attention to.

Usability testing includes:

• identifying problems and errors related to the usability of the application;
• recommendations for improvement.

• User interface testing

During testing, the main elements of the interface are checked: menus, toolbars, buttons, images, dialog boxes, input fields, list controls, etc.

Testing can be performed either manually or using various automation tools.

• Compatibility testing

The check reveals the compatibility of the application with different operating systems, server software, network bandwidth, browsers, screen resolutions, client configurations, databases, etc.

The main goal of such testing is to create a universal application and provide a positive user experience when interacting with it.

• Performance testing

The challenge of testing is to determine the maximum load that a product can withstand. It also checks the stability of the application, evaluates its capabilities in various configurations of the environment and the potential for scaling, identifies the limit at peak load, etc.

The AVADA MEDIA team provides design and professional testing of web services for business. Our approach includes a full range of development processes – from consultation to full product implementation and market promotion.

There are three main stages of software testing:

• Planning

Determination of functional and business requirements for the product, drawing up a detailed plan, selection of methods and verification tools.

• Data analysis and strategy development

Studying technical requirements, writing scripts that will allow you to check the functionality, determining the timing and testing environment.

• Software testing

Based on the data obtained, test scenarios are implemented, and errors in the application are identified, fixed and corrected. After that, preparations for the release of the product begin.

In addition to the basic types of verification, the company’s specialists conduct web application security testing, which requires fundamental technical knowledge and relevant specialized qualifications.

This type of check is especially important because it performs the following functions:

• Minimizing the threat of data corruption and theft.
• Checking the security of online transactions.
• Prevention of unauthorized access.
• Ensuring resilience of the application to cyber attacks.

In order not to leave “loopholes” for intruders and hackers, we use the XSS Filter Evasion Cheat Sheet and MySQL SQL Injection Cheat Sheet cheat sheets. Software testing has many benefits and can help solve a number of problems:

• Analyze the level of software quality and identify possible errors.
• Make sure the application works correctly under various conditions of use.
• Check that the final product meets all requirements.
• Eliminate performance defects.
• Optimize your hardware investment.
• Reduce service and support costs.

AVADA MEDIA conducts comprehensive web testing of software security and automates business processes of companies at all stages of the software life cycle. In our work, we apply proven practices for identifying software vulnerabilities, as well as monitor current trends in the field of cybersecurity.
