What Is the Role of QA in SDLC?

A report on the global distribution of software development operating systems from 2018 to 2022 suggests that Windows holds the top spot as the most popular development ecosystem. Following closely, Apple's MacOS ranks second in terms of usability.

The global software industry represents a vital cog in the IT machinery, driving innovation and progress within the ever-expanding market to deliver cutting-edge software products.

Developers have a plethora of programming language choices at their disposal.

Software Quality Assurance, commonly referred to as SQA, is a pivotal step in the software development life cycle (SDLC). The fundamental objective of QA is to guarantee that the developed software fulfills its intended function without any glitches. It should perform optimally under a wide range of conditions, ensuring freedom from bugs and defects.

In today's highly competitive scenario, to deliver top-notch software products, every phase of the SDLC includes a crucial quality assurance component. In this blog, let's delve deeper into how quality assurance impacts software and its myriad implications!

What are the Phases of the Software Development Life Cycle?

The steps of the software development life cycle are loop-structured and infinite. When one process is finished, a new one begins right away. The entire procedure becomes more adaptive, fluid, and dynamic through ongoing review of the final result.

Let's explore the 7 phases of SDLC :

Analysis

Before commencing the development process, you must comprehend what needs to be created. Here the SDLC phase rolls out! To build a suitable and dynamic product, you must understand what's available in the market and what trends are yet to arrive.

Planning

As you know what you're yet to do, it's essential to ascertain the best way. You must explore your final goal, what comes initially and last, what you should do to reach the goal, etc. The SDLC planning is about time, effort, and resource distribution.

Design

The creation process begins in the design stage throughout the software development life cycle. A software developer will produce a project design after the goal and requirements of the final product are established. The design often summarizes the framework and details of low-level parts and techniques.

Development

Once you have designed the product, this phase entails writing the codes. A software developer creates an executable program to perform particular operations and produce the desired outcomes.

Testing

To determine the product quality, any new modifications must be verified precisely before deployment. This SDLC testing stage aids in mitigating errors, discovering flaws, and ways to optimize them by exposing the code to an ecosystem identical to the end user experience.

Deployment

After screening is complete and all has been accomplished, it is time to implement all the improvements. During the SDLC implementation phase, the product is made accessible to the clients.

Maintenance

A finished product may look like a strange, evolving living being of some type. The goal of the maintenance stage of the SDLC is to monitor its health, maintain its operation, and examine its behavior.

Software QA Testing Best Practices

Your testing and QA plan is an ideal place to begin if the software development team has trouble performing application checks effectively. Issues should be prioritized and divided into groups based on grouping, importance, and intensity as part of a successful strategy.

The functional analysis methodology should include a comprehensive view of the faulty life cycle. So, Here are 7 quality assurance best practices as you proceed to complete the remainder of your testing and quality assurance approach:

Test each item separately

Tests must have explicit motives. Every test must concentrate on a wide array of features, such as security and user interface.

Know the testing types on offer

There are several types of software performance testing and optimization in the SDLC, from UAT to load testing, to ensure the differences and the right way to use them.

Employ regression tests

It is insufficient to validate a key functionality just once. Functionalities that formerly completed tests may be affected by updates to the code source.

Report and detect bugs

Establish the reporting process for bugs and the information required. Will you create a custom bug monitoring solution or adopt an open-source one tailored to your strategy?

Decide on the analytics

You need to keep track of different tests conducted and employ this data to ascertain where bugs can generate.

Opt for the appropriate test environments

Cover as many scenarios as possible, considering various OSs, gadgets, and user profiles.

Never overlook the UI

You may utilize functional tests conducted by human testers to obtain a feel for the app's

UI and execute end-to-end scenarios.

The Role of QA in Agile Development

As per the Global Software Testing Services Market 2022-2026 report, during 2022-2026, the software testing market will rise by $55.76 billion at a 15% CAGR rate.

Agile testing is now an integral element of the SDLC and will continue to be so in the years to come, according to the 15th State of Agile Report. It indicates a considerable increase in the implementation of Agile across teams working on software development from 37% in 2020 to 86% in 2021.

Testers and programmers must collaborate when using Agile development, and the roles may be switched around. Therefore, it's crucial that specifications be set in stone and that the staff is educated.

As soon as user narratives are written, testing will be used. The testing group and the development team must clearly understand the anticipated scope of work. The fundamental tenet of Agile development is openness.

Testing, as well as development, can both fall under the role of QA in agile development. It is intended that testers and developers work together effectively to supply code and finish the task following the client's specifications.

As an application is being developed, QA aids in preventing problems and possible shortcomings. Efficiency, performance, or security problems may also be helped. This will not only assure the application's reliability but also reduce testing costs when it is in the possession of the customers. Developers can proceed in this fashion rather than spending all of their time fixing problems or redoing work.

Although the testing period may be the one that immediately springs to mind, quality assurance professionals can assist in all stages of the SDLC. More than only discovering issues, QA may also focus on bug prevention.

Testing frequently and at an early stage in the SDLC will transform the job of QA into one of the catalysts for change. The quality of the products will increase, and this will satisfy customers.
