QA Best Practices_ How to Achieve Excellence in Quality Assurance_

Accomplishing brilliance in QA (Quality Assurance) is crucial for any business targeting to deliver high-end software products. Whether it is about reducing flaws and limitations, improving the user experience, or meeting audience expectations, top-notch QA practices play a pivotal role in the overall success of any project. 

A core practice in any robust QA strategy is Scenario testing, which simulates actual use cases to estimate how the system behaves in multiple circumstances. By focusing on these best practices, businesses can confirm they are catching vital glitches early, dropping expense and time overruns, and constantly delivering top-quality software. 

What is Quality Assurance all about?

It is critical to confirm that end products align and fine-tune with both external as well as internal needs and expectations. This discipline encompasses methodical processes to estimate and refine systems or outcomes. Its strategic role comprises conducting audits, defining standards, and expediting continuous improvements, eventually safeguarding user satisfaction and organizational repute.

Let’s see some of the instances of what QA might entail in diverse sectors:

  • Software Development: A Quality Assurance team tests a fresh application for features like responsiveness & user login, confirming it meets customer expectations before launch.
  • Healthcare: Validating medical devices, confirming the accurateness of patient records, and meeting standard regulatory standards for compliance and safety.
  • Pharmaceuticals: QA in pharmaceuticals includes testing drug compounds and scrutiny of production facilities to ensure safety and compliance with regulations

Importance of QA (Quality Assurance)

QA is essential to guarantee the quality of the quality, meeting user expectations, and relying on standard regulations. The major advantages include:

  • Customer Satisfaction: Quality Assurance guarantees functional and reliable products, increasing customer loyalty and trust.
  • Safety and Compliance: It confirms products meet legal needs and are safe, decreasing legal threats.  
  • Operational Effectiveness: By detecting inefficiencies, Quality Assurance decreases waste and optimizes resource usage.
  • Market Reputation: Quality Assurance builds a robust brand image & reputation, improving client confidence and strategic advantage.
  • Product Development: Quality Assurance improves product design with effectual feedback mechanisms and accelerates market readiness.
  • Cost Management: It cuts expenses linked to flaws and reworks by addressing glitches early in the software development cycle.
  • Competitive Advantage: Superior-quality products can set a business apart in competitive markets.

Quality Assurance reduces expenses, drives business growth, and enhances customer loyalty and product reliability.

Different Forms of QA Testing 

QA testing can be carried out using multiple methods. Listed below are some of the most common forms of QA testing.

  • Functional Tests: As the name denotes, functional tests concentrate on testing the functionality of a specific app. Functional testing includes offering several inputs, capturing the results, and validating them with the projected outcomes.
  • Unit Tests: The unit test is a form of automated software testing where separate software elements are individually tested to confirm their functionality. This technique focuses on testing the tiny code units, such as individual methods or functions, to detect and fix bugs early.
  • Non-functional Tests: In non-functional tests, all the non-functional components of the software are amazingly tested. It chiefly focuses on the performance, security, or data storage facet of the software.
  • Regression Tests: QA Professionals run regression testing to validate whether a current update or code modification in the software has caused flaws in any current features or not. Since regression testing is typically the same and should be fully or partially re-executed, QA is the most effectual method to conduct it.
  • Smoke Testing: A smoke test is a form of test automation that focuses on testing all the traits of the software. Smoke testing is conducted at the beginning of every test cycle to guarantee that the basic elements of the app are working as expected.

The most widely used and popular testing tool among all automated test tools listed is Selenium. It is a free-to-use and open-source automated testing suite of tools. It is extensively used for testing various web apps owing to its customizable automation testing traits. Selenium provides compatibility with multiple programming languages like JavaScript, Java, Python, C#, and more. Therefore, Selenium lets QA Experts automate website tests in any programming language.

  • Cypress 

It is a new automated test tool particularly built for front-end developers. Written in JavaScript (JS) & built on top of WebDriver and NodeJS, Cypress tests run in almost all web browsers. So it is simple to use, fast, & reliable. It is open-source and free to use.

  • Appium 

It is an open-source, widely-known, and popularly used tool for automation testing hybrid, native, and mobile web applications. Appium can run iOS, Android, & Windows apps that use the WebDriver protocol. The key idea behind the screens of Appium is when anyone tests a native application. It shouldn’t involve an application recompilation or SDK.

  • Puppeteer 

It is a JS (Javascript) library based on Node.js designed by Google that allows us to control headless Chrome via the DevTools Protocol. Such protocol offers an API for controlling headless Chrome or Chromium. Puppeteer allows us to automate the testing of our web apps. With it, we can conduct testing in the browser to see the testing outcomes in real time on our terminal.
