A software testing practice that follows the principles of agile software development is called Agile Testing. Agile is an iterative development methodology, where requirements evolve through collaboration between the customer and self-organizing teams and agile aligns development with customer needs.

Principles of Agile Testing

  • Testing is NOT a Phase: Agile team tests continuously and continuous testing is the only way to ensure continuous progress.
  • Testing Moves the project Forward: When following conventional methods, testing is considered as quality gate but agile testing provide feedback on an ongoing basis and the product meets the business demands.
  • Everyone Tests: In conventional SDLC, only test team tests while in agile including developers and BA’s test the application.
  • Shortening Feedback Response Time: In conventional SDLC, only during the acceptance testing, the Business team will get to know the product development, while in agile for each and every iteration, they are involved and continuous feedback shortens the feedback response time and cost involved in fixing is also less.
  • Clean Code: Raised defects are fixed within the same iteration and thereby keeping the code clean.
  • Reduce Test Documentation: Instead of very lengthy documentation, agile testers use reusable checklist, focus on the essence of the test rather than the incidental details.
  • Test Driven: In conventional methods, testing is performed after implementation while in agile testing, testing is done while implementation.

Advantages of Agile Testing

  • Customer satisfaction by rapid, continuous delivery of useful software.
  • People and interactions are emphasized rather than process and tools. Customers, developers and testers constantly interact with each other.
  • Working software is delivered frequently (weeks rather than months).
  • Face-to-face conversation is the best form of communication.
  • Close, daily cooperation between business people and developers.
  • Continuous attention to technical excellence and good design.
  • Regular adaptation to changing circumstances.
  • Even late changes in requirements are welcomed

Disadvantages of Agile Testing

  • In case of some software deliverables, especially the large ones, it is difficult to assess the effort required at the beginning of the software development life cycle.
  • There is lack of emphasis on necessary designing and documentation.
  • The project can easily get taken off track if the customer representative is not clear what final outcome that they want.
  • Only senior programmers are capable of taking the kind of decisions required during the development process. Hence it has no place for newbie programmers, unless combined with experienced resources.
