TDD, BDD and ATDD are concepts that have revolutionized the world of testers, in many cases changing mindsets, learning of new skills, changing attitudes and the way of working.

Test-Driven Development

TDD is a software development technique that practices writing tests that provoke “fail” to then refactor it.

Testing is done first, and then, the code is written.

Kent Beck, one of the 17 original signatories of the Agile Manifesto. Is credited with rediscovering Test-Driven Development.

TDD focuses on the implementation of features.
Developers are mostly involved in the writing of Unit Tests.
Written in programming languages such as Python, Java, etc.
These are very technical tests. Not easy for non technical profiles.
Focus is to write Unit Tests.

BDD Behavioral-Driven Development

BDD is considered an extension to Test Driven Development. Behavioral-Driven Development is a technique that practices creating simple scenarios on how an application should behave from the end user’s perspective.

BDD focuses on the system’s behaviour.
Developers, QAs and Customers are involved in this process.
It is easy for non-technical profiles to understand these.
Focus is on understanding the requirements.
ATDD Acceptance Test-Driven Development:
ATDD is a development methodology based on communication between the business customer, the developer and the tester.

Acceptance Test-Driven Development

ATDD focuses on capturing accurate requirements.
It is easy for non-technical profiles to understand these.
Focus is on writing Acceptance Tests.

By understanding these techniques, we know which strategy is the best fit for our Software Development projects at any given time. There is no hard rule to stick to one development technique and you can use a combination of these three techniques based on the requirements of your project, those of your team and yourself. An important element to consider is which tool to choose to assure the highest quality and efficiency of your testing process. Let us help you.

TAST (Test Automation System Tool) is a comprehensive cloud test automation platform developed by SIPSA (Servicios de Informática Profesional S.A.) aimed at automating and streamlining the testing process, it is targeted at end users, testers and quality assurance teams. TAST is user friendly, codeless and helps speed-up quality and maintenance of your software development.

With TAST (Test Automation System Tool) the user can start to define the test case even without having the application defined. The user can describe what the case flow is (visually) and leave it ready for when the SW is delivered.

We are going to show you an example:

In the diagram the user can define step by step what he/she wants or expects. And as soon as the software is available, it is possible to test whether the designed case works against the delivered program. With TAST, in any message you can define the expected result, you can even enter add images of how you would like the application to look.

TAST(Test Automation System Tool) helps teams apply TDD, BDD and ATDD techniques from the beginning of the project.
