Agile testing is a software testing practice that follows the Agile software development methodology. In Agile development, projects tend to evolve during each sprint among collaborators and shareholders. Agile testing focuses on ensuring quality throughout the Agile software development process.Continuous integration and continuous delivery are two important aspects of agile testing. In continuous integration, developers integrate their code changes into a shared mainline several times a day. In continuous delivery, every change that passes all tests is automatically released into production.Agile software testing is a dynamic approach to software development that emphasizes iterative cycles of development and testing, enabling teams to adapt to changing requirements and deliver high-quality software efficiently.
Unlike traditional waterfall methodologies, Agile testing integrates testing throughout the entire development process, with continuous feedback loops between testers, developers, and stakeholders. Testers collaborate closely with developers and business representatives to define test cases, prioritise testing activities, and automate repetitive tests, ensuring rapid and reliable delivery of features. By fostering transparency, communication, and flexibility, Agile testing empowers teams to respond swiftly to customer feedback, minimise defects, and deliver valuable software increments frequently, enhancing overall product quality and customer satisfaction.
The history and evolution of Agile software testing trace back to the early 2000s when a group of software developers authored the Agile Manifesto, a document outlining principles for iterative and collaborative software development. Initially, Agile methodologies primarily focused on development practices, but it soon became evident that testing was integral to the Agile process. In traditional waterfall models, testing occurred predominantly at the end of the development lifecycle, leading to delayed feedback and increased risk. Agile methodologies, such as Scrum and Extreme Programming (XP), advocated for a shift-left approach, where testing was integrated throughout the development process. This integration fostered close collaboration between developers, testers, and stakeholders, enabling quicker identification and resolution of defects. Over time, Agile testing practices evolved to embrace automation, continuous integration, and test-driven development (TDD), further enhancing efficiency and quality.
Additionally, the emergence of DevOps practices encouraged tighter integration between development and operations, leading to the concept of continuous testing, where testing occurs continuously throughout the entire software delivery pipeline. Today, Agile testing continues to evolve with advancements in technology and methodologies, such as Behavior-Driven Development (BDD) and Shift-Right testing, emphasizing the importance of adaptability, collaboration, and customer-centricity in delivering high-quality software.

Transitioning from a preference for the Waterfall approach to Agile methodology was necessitated by the challenges encountered in projects demanding continuous client delivery, frequent change requests, and complexities in code management. The rigidity of the Waterfall model became increasingly problematic when confronted with the need for adaptability, responsiveness to client feedback, and dynamic project requirements. Consequently, the decision was made to embrace Agile methodology to better address these challenges. However, during the transition process, several issues surfaced, both in shifting from Waterfall to Agile and in implementing Agile practices fully, particularly when transitioning from partial to comprehensive Agile adoption.
