TDD, BDD, and SDD stand for Test-Driven Development, Behavior-Driven Development, and Specification-Driven Development. You might be wondering what these terms mean. Well, they are software development techniques. If you wish to increase your understanding of the subject, then you should continue reading and this blog will help you understand why large enterprises, as well as small businesses, love to go with the best customized IT services and solutions company. 

Software development is a massive world, especially in today’s technologically advanced age. It’s full of frameworks, methodologies, and processes. Most of these things promise to be better than the others in terms of development. Any developer from customized IT services and solutions company will say that they are happy to share their understanding of these matters. They will even discuss their favorites or suggest the method that you should use.

If you’re going to implement a significant project, and if you want it to be successful, then these tech wizards can suggest methods. If you’re attempting to avoid disputes between design documents and everything implemented, then they will tell you about frameworks that are appropriate for the task. Also, if you want your project to have minimal regression combined with maintainability, then they can provide you with information about processes that you should follow. There are reasons why businesses are looking to get the best customized IT services and solutions company 

However, the complexity of your projects will increase with time. Naturally, you won’t be able to keep working with one method. If you do, then the technique won’t provide the benefits and value to your project, as well as the user. Generally, software development experts combine several methods to solve complicated problems.

The Methodologies

Customized IT services and solutions company promise better development using a hybrid solution of multiple methods. However, software developers don’t choose methodologies randomly and use them. They have to be complimentary. They also have to pick up precisely where another falls short, and they should provide their unique value to ensure predictable and productive outcomes. In that regard, the perfect combination is TDD, BDD, and SDD. Businesses are always looking to get the best customized IT services and solutions company for their requirements. 

About TDD

TDD is the abbreviated term for Test-Driven Development. It’s a software development technique used by an end-to-end IT services company where they create the test cases before writing the code below those test cases. While TDD is a development methodology, it also comes in handy during automation testing development. The teams that use TDD often take more time to complete the project. Then again, the program created using TDD tactics has little to no defects at all. TDD encompasses quality improvements in terms of code, which is also more reusable and flexible. Additionally, TDD aids in achieving high test coverage of about 90% to 100%. The trickiest task for developers following TDD is to write the test cases before writing the code.

Know About The Process of Software Development Techniques

The Process

Here are the steps associated with the TDD methodology.

  • Writing a test case – Developers write an automated test case based on the requirements
  • Running the test cases – After writing the test cases, developers run the automated ones on the currently developed code.
  • Creating the code for the test cases – If the test case fails, then the developers write the code to ensure that the test case works as it should.
  • Rerunning the test cases – After that, the developers rerun the test cases to check whether all the test cases are under implementation or not.
  • Refactoring the code – It’s an optional step, but refactoring is essential if the developer wants to make it more readable and reusable.
  • Repeating the steps from 1 to 5 – Finally, the developers repeat the cycle for the other test cases until they implement everything.

About BDD

BDD is the abbreviated term for Behavior-Driven Development. BDD is nothing more than an extension to TDD. In BDD, developers start by writing a behavior instead of test cases. Then, they move on to develop the code required for the application to perform the behavior. The entire BDD approach makes things easier for the developers and testers of an end-to-end IT services company. It even simplifies everything for business users. In reality, BDD allows all three players to collaborate. Veteran software developers believe that BDD is the best when it comes to automated testing. After all, it focuses on the behaviour of the application instead of thinking about code implementation. The limelight remains on the behaviour of the application in the BDD methodology. As a result, you can hire dedicated developers and testers to get a chance to view things from the customer’s perspective and for the wonderful customized IT services and solutions company. 

The Process

Just like TDD, BDD has several steps.

  • Writing the application behaviour – The product owner, the business analysts, or the QAs write the behaviour of an application in English-like language.
  • Writing the automated scripts – Then, developers convert the English-like lingua into programming tests.
  • Implement the functional code – Developers implement the functional code underlying the behaviour.
  • Checking the behavior – Developers have to run the behaviour to see if it’s successful or not. If it works, they move on to the next one. Otherwise, they have to fix the errors in the functional code to achieve the desired application behavior.
  • Refactoring or organizing the code – As already mentioned earlier, refactoring or organizing the code makes it more readable and reusable.
  • Repeat the steps from 1 to 5 – Finally, developers may have to repeat the steps to implement more behaviours in your application if you need them.

About SDD

In the end, there’s the SDD or Specification-Driven Development technique. It provides the developers of a software development company with a chance to use TDD and BDD techniques in the same development. It plays the role of a contract-aware programming language, as well as a suitable testing framework. The best thing about SDD is that it doesn’t dictate a developer’s choice. The specialist may want to start with TDD or BDD, whichever works for the project. However, SDD always emphasizes transforming the requirements of a customer into compilable and executable code. Another advantage of SDD is that it provides more than what TDD and BDD can offer individually.

Final words

Now that you have a basic understanding of TDD, BDD, and SDD, you should get in touch with a customized IT services and solutions company. Only such an establishment can make use of these methodologies and more for the creation of your unique and exclusive software program.
