Agile Methodology in QA: Power of Flexibility in Software Testing

Many organizations have adopted an Agile approach during the pandemic, as evidenced by data published in Forbes. Research from digital.ai indicates that the adoption of Agile among development teams has increased from 37% to 86%, and it has doubled among non-IT groups. 

Agile methodology in QA represents a paradigm shift in project management, prioritizing adaptability, stakeholder engagement, and iterative progress. It fundamentally redefines the approach to development and delivery by dividing projects into small, incrementally improved components, facilitating continuous evaluation and adjustment. This methodology fosters a collaborative environment among cross-functional teams, encourages direct communication, and emphasizes customer feedback as a central component of product development. Agile principles and practices enable organizations to respond swiftly to market changes, enhance product quality, and ensure alignment with customer needs and goals, optimizing project outcomes in dynamic and complex environments. 

Why is Agile methodology in QA relevant now? 

Organizations are already actively employing Agile methodologies such as Scrum and Kanban. Scrum focuses on iterative progress through defined sprints and roles, facilitating team collaboration and project transparency. Kanban emphasizes continuous delivery without overburdening team members, using a visual task board to manage workflow. The essence, however, lies in the continuous improvement and reflection on one’s experiences to enhance processes and outcomes. 

What about testing? 

The main aspect of the QA process in Agile is the continuous cycle of product development and improvement. Quality assurance plays a key role here. Constant and systematic testing is an integral part of developing new product functionalities. This allows teams to quickly identify and correct errors, ensuring high product quality at every stage of its development. Furthermore, the quality assurance process evaluates the clarity and adequacy of documentation, the effectiveness of communication between testers and developers, and the quality and comprehensibility of requirements. Based on these assessments, enhancements to the product's quality and development process are proposed. 

This article will detail the main principles, methods, and advantages of using this approach during software testing. 

Agile & Scrum Model in Software Testing 

In today's software world, "Agile" and "Scrum" have become synonymous with speed, flexibility, and convenience. However, it is important to understand how these concepts affect the testing process. 

What is Agile and Scrum methodology in software testing? 

The software testing process in Agile development is based on an iterative approach that emphasizes interaction and collaboration between teams. 

Scrum is a methodology that implements the Agile approach with sprints limited in time.  

The Main Principles  

Every developer, tester, or project manager should understand the benefits and opportunities that automation provides to ensure maximum productivity and product quality.

As an iterative development methodology, Scrum often requires rapid cycles of testing and adaptation. Test automation in the Scrum model in software testing makes an invaluable contribution to meeting these needs. Here are some key benefits: 

Correctly built software testing in Agile development projects ensures reliability and compliance with quality standards. 

Old-school Testing Methods or Agile Testing: Which to Choose for Your Project? 

In today's software development world, product testing approaches are constantly evolving. The choice between traditional and Agile method in software testing is often a key decision for organizations that affects speed to market, quality, and responsiveness. To better understand these two approaches, we have prepared a comparison table to help navigate their key characteristics. characteristics. 

The choice of approach depends on the project's specifics, the team's needs, and the desired results. For some organizations, combining elements of both approaches will be optimal, which will allow them to get the maximum benefit from each of them. 

What does Scrum demand from the testing? 

As an agile methodology, Scrum reformulates the approach to development and testing processes. For a tester, this affects many aspects of his work life, from his role in the project to his interaction with other team members.  

• Clear understanding of business logic: In Agile environments, testers must communicate more extensively with developers and stakeholders to better understand the business logic, directly influencing requirements and acceptance criteria. 
• Use automation for regression testing: Tools like Playwright or Appium help testers perform continuous regression testing quickly and efficiently. 
• Adhering to the SDLC from the beginning: The tester is no longer the "last line of defense" before releasing the product. He actively participates in all stages of development, making it possible to identify and eliminate problems much earlier. 
• Regular stand-up meetings: Regular stand-up meetings allow testers to stay up-to-date on the latest changes in the project, discuss potential issues with other teams and stakeholders, and ensure constant progress on various tasks. 

Scrum brings significant demands to the tester's work, making him more involved in the development process and encouraging him to actively participate in the project. Testers get more responsibility and opportunities for professional growth and discover new tools and techniques. The Scrum model in software testing changes the tester's role in the team and requires him to take a new approach to his work, focused on cooperation, communication, and continuous learning. 

What Should a Tester Know to Work in an Agile Process? 

Moving from a traditional waterfall model to Agile in software testing can be challenging. But the right preparation can make this transition smoother. Here are the key aspects that a tester should pay attention to:  

Mastery of automation tools
