Agile is a coding practice that follows the rules and principles of agile software development. In this Agile Tutorial, you will learn the fundamentals of Agile, Agile models and methodologies, Agile Vs. Scrum differences, Scrum master training to Agile testing interview questions & answers. This Agile development tutorial is an absolute beginners guide to Agile, and Scrum testing, Basic understanding of manual or automation software testing will be beneficial.
Iterations are the basic building block of Agile development. Each iteration is a standard, fixed-length timebox, where Agile Teams deliver incremental value in the form of working, tested software and systems. The recommended duration of the timebox is two weeks. However, one to four weeks is acceptable, depending on the business context. Iterations provide a regular, predictable cadence for teams to produce an increment of value, as well as to refine those previously developed. These short time periods help the team, Product Owners, Product Managers, and other stakeholders regularly test and evaluate the technical and business hypotheses in a working system. Each iteration anchors an integration point, a ‘pull event’ that assembles various system aspects—functionality, quality, alignment, and fitness for use—across all the teams’ contributions.
Since the shortest sustainable lead time is a significant goal of Lean-Agile development, Agile teams execute a full plan-do-check-adjust (PDCA) cycle as quickly as possible. The PDCA learning cycle (shown in Figure 1) represents the following iteration events:
Master Story - Our to-do list on an agile project
Team Velocity - The speed at which we turn user stories into working software
Planning - iterations = total effort / estimated team velocity
Refactoring - As we add more functionality to the system we need a way of maintaining our design and keeping our house in order.
