QA in Agile Development

Agile techniques have evolved as a key approach to efficiently producing high-quality products. Unlike traditional approaches, where Quality Assurance (QA) is typically a final step, the Agile development process incorporates QA throughout the whole development lifecycle, from first design meetings to final testing. To avoid testing becoming a bottleneck in Agile processes and to ensure high-quality software, QA must keep up with the software development process, which requires smooth alignment between the two.

This article discusses Agile development and the best methods for incorporating QA into Agile to ensure that the final product meets the highest quality requirements.

Understanding Agile Development

Agile is a mentality and iterative approach to software development and project management that allows organizations to thrive in uncertain situations. An Agile development approach focuses on the quick and frequent delivery of quality software products through an iterative and incremental process.

Traditional software development teams usually follow a process that starts with the creation of a detailed project plan before moving on to step-by-step development process with set deadlines and no deviations. When requirements change, there is no going back or repeating. Rather than outlining the complete project ahead of time, Agile teams plan continually and alter as changes occur.

What is Quality Assurance (QA)?

Quality assurance is the systematic process of providing products and services according to specified quality requirements, ensuring customer expectations are taken into account. It involves a set of procedures to help prevent errors in the final product and ensure that it conforms to the specified requirements.

It has multiple stages, including:

  • Requirement Analysis: Determining and documenting what the software should perform.
  • Test Preparation: Developing test strategies and cases based on the requirements.
  • Test Execution: Run the tests to check for bugs and deviations.
  • Defect Tracking: Documenting and managing any issues discovered during testing.
  • Report Writing: Documenting the results and giving input to the development team.

Role of QA in Agile development

Quality assurance in Agile is not a separate stage but rather an essential part of the development process.  Traditional Waterfall approaches put QA at the end, while Agile uses QA throughout the development process.

This continuous integration of QA helps to detect and handle issues early, saving the expense and effort of fixing errors later.

  • Continuous integration and testing

In Agile, quality assurance activities are done throughout the application development lifecycle rather than being limited to a single phase. This means that testing occurs continually, alongside development. This allows errors to be spotted and handled early on.

  • Collaboration & communication

QA experts work closely with developers, testers, and others. This teamwork guarantees that everyone has clear knowledge of the objectives and has the same requirements and expectations.

  • Continuous feedback

Agile stresses continual feedback, and QA plays an important role in it. By giving timely feedback on product quality, QA enables the team to make educated decisions and effectively prioritize work.

  • Concentrate on the user experience

QA in Agile entails more than just finding problems; it also entails creating a positive user experience. This covers not just functionality testing but also usability, performance, and security checks. By focusing on the end user, QA helps produce applications that meet user needs.

Best practices for QA in Agile development

QA is crucial in Agile development to ensure that software fulfills high quality criteria while keeping  the application’s flexibility and speed.

Below are some suggested practices to consider:

Early and Continuous Testing

  • Shift Left Approach

The “Shift Left” technique is one of Agile QA’s key approaches. This involves QA from the start of the development process. This allows possible difficulties to be discovered and treated early on, preventing them from developing into severe problems later on. This strategy saves time and resources and also ensures a higher quality result.

  • Continuous Integration and Deployment (CI/CD)

Implementing CI/CD procedures is critical for Agile QA. CI/CD ensures that code changes are automatically tested and distributed, encouraging continuous feedback and development. Automated tests are run with each code update, detecting problems early and allowing for speedy repairs. This continuous testing cycle maintains the highest level of quality throughout the development phase.

Collaboration & Communication

  • Cross-functional teams

Agile values teamwork, and QA is no exception. Cross-functional teams include QA, developers, and other stakeholders; they enable greater understanding and faster resolution of issues. This collaborative environment guarantees that everyone is in line with the project’s goals and quality standards.

  • Regular meetings

Regular meetings, such as sprint reviews, are important to maintain open communication. These meetings provide a way to discuss progress, identify any issues, and plan next steps. Regular meetings keep everyone informed and engaged, ensuring that quality is of utmost importance.

Test Automation

  • Automate repetitive tests

Automating repetitive and time-taking tests speeds up the testing process and allows manual testers to focus on more complex situations. Automated tests can be done regularly, providing fast feedback and guaranteeing that new changes to codes do not bring new bugs.

  • Strategic automation

While automation is useful, it is critical to decide what you automate. Not everything should be automated. Focus on automating the tests that add the most value and are stable enough to benefit from automation. This strategy ensures that automation efforts are efficient and effective.

Concentrate on one functionality

  • Focus on a specific function

Favor a concentrated approach to Agile testing, focusing on one feature at a time. Engage the entire Agile team in aligning test case preparation with specific feature and functionality testing, then reviewing and confirming test cases for accuracy.

Risk-Based Testing.

  • Prioritize testing according to risk

In Agile, it is important to prioritize testing efforts on the basis of risk. Identify and first consider the most important part of the application. This allows QA teams to ensure that all critical portions of the application are adequately tested, decreasing problems in the final result.

Exploratory Testing

  • Encourage Exploratory Testing

Exploratory testing is a useful tool in Agile QA. It helps testers explore the program without relying on specific test cases, find unexpected errors, and enhance overall product quality. Exploratory testing helps to find edge cases and scenarios that automated tests may not find, offering a more comprehensive review of the application’s quality.

Continuous improvement

  • Retrospectives

Continuous improvement is a fundamental concept in Agile. Conduct regular retrospectives to determine what worked and what may be improved. Use this feedback to keep improving the QA process. Retrospectives allow the team to learn from past experiences and make improvements for future performance.

Minimize Documentations

  • Value-driven documentation

Create documentation only if it adds value to the team and project. Focus on documents that are critical to the development and testing processes, such as user stories, acceptance criteria, and test cases. Avoid developing voluminous documentation that is not directly related to the project’s success.

Training & Development

  • Continuously train team members

Having regular training for QA team members is critical for keeping them current on the latest technologies, techniques, and best practices. Continuous learning ensures that the QA team is skilled and has knowledge of dealing with new issues, contributing to the overall success of the Agile project.

Cloud Platforms

  • Cloud platforms ensure consistent quality

Continuous quality cloud systems, such as LambdaTest, can help you meet Agile testing needs more easily. LambdaTest offers a scalable cloud platform for manual and automated scenario testing of web and mobile apps across 3000+ real browsers, devices, and OS systems. This versatility enables teams to test in a variety of contexts, assuring complete coverage and speedier feedback cycles. Agile teams can improve their testing capabilities, save infrastructure expenses, and increase overall efficiency by utilizing cloud platforms.

Customer Focus

  • Understand user needs

In Agile, it is critical to produce software that fulfils the needs of the customer. Ensure that the QA process is according to the user requirements and expectations. This entails understanding user requirements and incorporating them into the testing process. By emphasizing customer satisfaction, QA teams can help provide a product that gives a better user experience.
