Before we start the difference between TDD vs BDD, we should know what is TDD and BDD.
TDD stands for ‘Test Driven Development. TDD is used for the Software Development process. It works on simple principles like developing and correcting failed test cases before developing new test cases. It helps developers to minimize redundant code. In TDD Team should have knowledge of programming language. Using It team can achieve 100% results.
|It is a traditional method, No mandatory rule is used.
|In TDD programming language is used as per the requirement.
|There is no sequence to follow.
|There is one sequence to follow.
|In Traditional testing, the team cannot proceed further with a known issue.
|In TDD team can ‘proceed further with some known issues.
|It does not provide guarantees for the standard.
|It provides guarantees for the standard set for it.
|100% test coverage cannot be achieved. Because Traditions testing is not a sequential procedure.
|100% test coverage can achieve. It is a sequential procedure.
BDD is a Software Development process, it is derived from TDD. TDD is the foundation level of BDD. Behavior-driven development is a way of communication among the technical team – non-technical team and stakeholders.
So for easy communication simple English language is used to create BDD. BDD is helpful to create strong collaboration between stakeholders and stoke holder. For BDD’s business value and needs, both are important. BDD is very simple to understand for the non-technical person.

Using BDD we can create test cases with easy-understanding language.
Find the difference between TDD and BDD here:
|Its abbreviation is ‘Test Driven Development.
|Its abbreviation is ‘Behavior Driven Development
|1st step is to prepare a test case.
|1st step is to prepare the scenario according to an expected result.
|The primary task of TDD is to prepare for how the task is implemented.
|The primary task of BDD is to check the behavior of an application for the end user.
|It is written in technical language.
|It is written in non-technical (Easily understandable) language.
|Changes made in application requirements impact more on TDD test cases more.
|Functional changes in application requirements do not impact BDD.
|Communication is required among developers.
|Communication is required among the entire teammates.
|It is used with projects which used API and third-party tools.
|It is used with an E-commerce website and application system.
|Junit, TestNG, and NUnit Support TDD.
|SPecFlow, Cucumber, and MSpec support BDD
|To understand TDD, the programming language is mandatory.
|BDD is easy to understand.
|There are minimum chances to have bugs.
|There are maximum chances to have bugs.
In this article, we have seen the difference between TDD vs BDD. TDD and BDD both are methodologies to work with projects. They both have their own demerits and merits. So it’s up to the team to decide which methodology they want to use in their projects.
