Basics of Agile Testing


The word AGILE means something that can be carried out or moved quickly and easily. Thus, agile testing may be interpreted as a quick and easy going testing process and activity. Agile testing is a progressive and dynamic type of testing which is carried out on regular basis along with the development in each iteration of the development life cycle.

agile meaning

Well to go in-depth into the phenomenon of agile testing, it stands vital to come across the history of agile testing. The paradigm of agile testing is though not as new, but it seems to be the same as people are not much familiar with the term. The agile software development was actually launched back in the year 2001. The crux is that the concept existed far before, but the way of expressing has been different.

Before, going in detail, for the agile testing, let's have a small overview of the agile software development methodology.

What is agile methodology for software development?

It is a specific approach to carry out the process of software development to develop and provide the software product in minimal time with the least possibility of defects to client after each and on trial basis for accepting their reviews and requirements, which are being implemented in the next iteration of the development life cycle.

Generally, the requirements are evolved through continuous collaboration of the client and teams, involved in the development. It is a dynamic, repetitive & progressive process that requires one or more than one iteration to implement the frequent incoming & dynamic requirements after each iteration until the final product to be delivered fulfils & satisfies all the criteria/requirements provided by the client before & during the development process.

What actually is Agile Testing?

The centre or focus in agile testing is laid on iterative development and delivery. It delivers a unique approach to the computer programming scenario. It can be said that agile software development or testing is something that involves breaking projects into a series of regular and predictable iterations. Customer satisfaction is the primary concern that is provided by delivering the software quickly with the best of the features.

One of the most sorts after methodology under agile testing happens to be the scrum framework. It is a well structured approach that encourages cross-functional team effort, regular communication and a dedicated focus towards common goals. Other approaches of agile testing includes Extreme Programming, Feature Driven Development, Dynamic Software Development Method, Lean Software Development and Crystal methodology

Agile Testing Quadrants

Agile testing quadrants may be seen as an established procedure or guidelines or steps to carry out the end-to-end agile testing of a software application in four different phases, imparting different testing techniques for different levels and purposes.

What are the Advantages of Agile Testing?

From years, agile software testing has been a vital part in IT field. This success of the scenario accounts to the benefits that it provides. Here below are some of the finest advantages that it incurs.

  • Greater Productivity

Since, in the agile software development, the workload is divided into chunks, this restricts programmers to go off track. Since discrepancies are less are productivity goes higher.

  • Higher Quality

Agile software testing accounts to a better end product that is easier to test and validate along the way. This definitely leads to lesser errors and higher productivity.

  • Predictable Costs

Since cost estimates are required in the beginning itself, estimation of costs becomes more transparent.

  • User's Feedback and Reviews

Engagement of customers or end-users in the agile methodology of development & testing helps in improving the quality and features of the software product in a very easy manner as feedbacks and reviews are getting received directly from the end-users.

Disadvantages of Agile Testing

Each and everything have some or more both advantages and disadvantages. Agile testing is a productive approach of testing the software application but still some of the key-elements or points as stated below reflect the disadvantages of using agile testing.

  • Less or no documentation results into unambiguous requirements and specifications which makes difficult to predict expected outcomes.
  • Efforts required in testing the application become unpredictable for the QA/ testing team.

As agile model involves less or no documentation, it creates difficulties for the testing team to predict the expected results and to decide direction and path of the testing to be carried out. These difficulties may be overcome by making use of the agile testing checklist to ensure better and qualitative testing in a guided manner.

In nutshell, it may be stated that agile approach is very much different to waterfall or traditional development. Unlike waterfall model where testing activities are carried out post development of the software application, agile testing delivers a dynamic and productive approach in today's unpredictable and dynamic environment to perform testing frequently on regular basis throughout the development process.
