What Are the Best Practices for Quality Assurance?

The demand for and success of a software product in the target market will depend on what practices for quality assurance were used to improve its quality at all stages of its life cycle.

Practices for quality assurance allow you to achieve the highest quality possible for large releases that include a certain number of significant and minor features. However, the QA process begins long before the actual product code is written and does not end after the software is released to the target market.

During the processes included in the QA complex, the following activities are performed:

● determination of the main criteria and requirements for the quality of design and code of the software products;

● writing test documentation which lists the key items of the product being checked, the tools used, working environments, and project acceptance criteria;

● creation of test cases for each level of product verification (modular, integration, system, acceptance);

● checking the code and external behavior for each product function;

● customer feedback support.

There are several methods of work used in QA. Basically, they are associated with the stage of testing the software products, that is, identifying their compliance with certain requirements and suitability for use. At the same time, the creation of test cases includes such stages as planning, monitoring, and control, analysis, design, implementation, realization, and completion of test scenarios. Within these stages, there are groups of activities that can vary depending on the final goals and QA plans.

Practices for Quality Assurance Types

Depending on what type of software product goes through the QA procedure, each type of work has its own specifics.

Practices for the test application

Within this QA area, the following methods of product quality control are used:

●     definition of a functional specification, meaning a list of product functions that need to be tested;

●     development of test cases that provide full coverage of all test events;

●     defining entry and exit criteria.

In addition, based on the results obtained during functional, non-functional, and acceptance testing, groups of QA managers carry out various types of monitoring, control, and analysis of data that affect the quality of the product.

Practices for mobile testing.

When conducting QA events designed to improve the quality of software products (websites, applications) for mobile devices, various methods are used, focused on checking the quality of various builds and newly created software for their reliability, security, cross-browser and cross-platform compatibility, resistance to loads and performance.

At the same time, testing of software products for desktop and mobile devices is performed on real equipment, in interactive mode, according to the black box testing strategy, that is, based on the external behavior of products, without access to their code.
