Everything You Need to Know About QA in Software Development

May 31, 2023


Want to know what is QA in software?

Quality in software as a general subject is hard to determine, and each person involved can have a different perspective. But when it comes to software quality assurance, there are some common standards and processes that should be followed.

Quality is defined as the degree to which software meets or exceeds specific criteria. Quality assurance (QA) is a preventive measure that seeks to embed high-quality standards throughout the software development life cycle.

Thus, QA is about preventing issues and ensuring the development process is of high quality. It includes systematic activities and methods to define and maintain standards, procedures, and techniques.

Besides quality control, QA is also concerned with preventing issues through process-oriented activities, while QC focuses on detecting and correcting issues through product-oriented testing and inspection activities.

QA is Crucial for Successful Software Development

QA helps organizations ensure that their applications are efficient, secure, trustworthy, and compliant with regulatory and industry-specific requirements.

Here at WillDom we know that implementing QA practices help organizations identify and rectify defects, vulnerabilities, and performance issues early in development, which prevents costly setbacks and ensures a high-quality end product.

The Benefits of Implementing QA Practices

Software Quality Assurance (QA) benefits software development projects and organizations.

Some key benefits of implementing software QA include:

  • It saves money and time by avoiding costly and time-consuming errors.
  • QA ensures the software meets the defined requirements and functions as intended, leading to a higher-quality end product.
  • By conducting user-centric testing, quality assurance professionals identify and address usability issues, improving the overall satisfaction of end-users.

QA Teams are Needed to Safeguard Software Quality

QA teams play a crucial role in safeguarding software quality throughout the development process and promoting continuous improvement. They have specialized knowledge and skills in testing methodologies, techniques, and tools.

From start to finish they work closely with stakeholders, developers, and designers to understand requirements, provide feedback, and identify potential issues. Quality Assurance Engineers deliver valuable feedback and insights based on testing results, user feedback, and industry best practices.

Having a QA team involved from the start ensures that you have high-quality software that meets user expectations, enhances reliability, and drives business success.

How does QA work?

Quality assurance (QA) is a crucial step when developing new software products. Experienced teams understand that software quality assurance (QA) is a necessary procedure that adds value beyond testing and guarantees that the final product will perform as expected.

Quality assurance engineers (QA engineers) are an essential part of the software development team. They must be involved in the software quality assurance processes.

Most of the time, they implement ISO 9000, a set of international standards for quality management and assurance that helps companies from all industries record their quality systems.

Regularly, the QA process includes:

  • Review of requirements
  • Test planning/writing test cases
  • Unit testing activities
  • Integration testing activities
  • System testing
  • Performance testing
  • Security testing
  • Cross-browser testing / cross-platform testing
  • Updating test cases
  • Regression testing
QA is a crucial part of software engineering.

Different Types of Software Testing Involved in QA

Different types of software testing are employed to verify and validate a software application’s functionality, performance, and usability.

These are the most common types:

Unit Testing

This type of testing focuses on verifying the functionality of individual components or units of code. Developers typically perform it and ensure each unit works as intended in isolation.

Integration Testing

Conducted to test the interaction between different components or modules of the software after they are integrated. Also, it checks if the integrated units function correctly and communicate appropriately with each other.

System Testing

It is performed on a complete, integrated system to evaluate its compliance with specified requirements. It verifies the system and ensures all components work together as expected.

Regression Testing

It is executed by QA professionals to validate that recent changes or modifications in the software have not adversely affected previously working functionality. It involves retesting the existing features and functionalities to catch unintended side effects.

Functional Testing

Validates the functional requirements and specifications of the software application. It verifies whether the system behaves as expected and meets the applicable requirements defined for it.

Acceptance Testing

Also known as User Acceptance Testing (UAT), involves testing the software from an end-user’s perspective. Users or client representatives perform it to ensure the software meets their requirements and is ready for deployment.

Black Box Testing

It is a technique that focuses on the behavior and functionality of a software application without any knowledge of its internal structure or implementation details. In black box testing, the tester treats the software as a “black box,” where they are only concerned with the inputs and outputs and the system’s expected behavior.

Quality Assurance Best Practices

Quality assurance (QA) is essential to the software development life cycle since it helps find and fix problems before they affect customers and ensures that quality standards are considered.

Here are some best practices for effective QA:

  • Start testing as early as possible in the development process.
  • Create a detailed test plan that outlines the objectives, scope, and strategies for testing.
  • Establish clear acceptance criteria for each feature or user story.
  • Automate repetitive and time-consuming tests using appropriate tools and frameworks.
  • Conduct thorough security testing to identify vulnerabilities, perform penetration testing, and ensure compliance with security standards and best practices.

How does QA fit into Agile and DevOps methodologies?

QA plays a crucial role in Agile and DevOps methodologies by seamlessly integrating quality assurance practices into the software development process.

QA is incorporated within each iteration or sprint in Agile, enabling continuous testing and feedback loops to ensure high-quality deliverables. QA teams collaborate closely with developers and stakeholders, employing techniques like test-driven development (TDD) and behavior-driven development (BDD) to validate requirements and refine software functionality incrementally.

On the other hand, in DevOps, QA becomes an integral part of the continuous integration and continuous delivery (CI/CD) pipeline. By automating test scripts and employing robust test environments, QA teams contribute to rapidly and reliably deploying software updates.

How can QA help improve the user experience of software?

QA enhances the user experience of software by ensuring its usability, functionality, and reliability.

Rigorous testing, including functional, regression, and performance testing, helps identify and eliminate software flaws before they reach end-users, resulting in a smoother, more reliable software experience.

By prioritizing user-centric testing, QA ensures that software aligns with user expectations, bolstering overall satisfaction and loyalty.
