Difference Between BDD and TDD

What is BDD?

Behavior Driven Development (BDD) is a methodology that focuses on testing a program. It’s the most suitable way to test for small-to-medium sized companies.

BDD has proven to be an effective way of making sure that every piece of code in your program is as easy to test as possible.

In order to make sure your project will work properly, it’s important to use these two techniques together. As opposed to one or the other, both can help you create an effective and efficient software product in a very short period of time!

What is TDD?

Test Driven Development (TDD) is a software development methodology that focuses on developing the functionality of your product before you even write a single line of code. This technique is especially useful for large companies that need to develop their products in a short period of time.

The best part about TDD is that it allows you to verify the functionality of your product by testing the results against the actual specifications, instead of just making sure everything works when you’re done writing code.

The Test-Driven Development approach is known as “test-driven development” because it relies on creating tests that describe what we want our program to do, and then building our program by writing the code to meet those tests.

If we write our tests first, then we can ensure that our program actually does what we want it to do. When writing the code, if any parts of our program don’t work as expected, then we can easily identify where those parts are broken. Then we can fix them before writing any more code!

In order to understand the difference between Behavior Driven Development and Test Driven Development, it’s important to understand how they work.

BDD relies on BDD as a process that helps you write your program by writing tests first. It is like having a full-time developer who constantly writes tests for your program, while the rest of the team continues to write code. This way, you will always be able to tell whether or not your program is actually working as expected.

Test Driven Development relies on writing tests before you write any code at all! This technique allows you to test all of your functionality by using the test cases that you already have written for your product.

You can then use these tests as specifications for the next piece of code that you write. In this way, Test Driven Development also helps make sure that your program works properly!

If we combine both BDD and TDD together, we can achieve a very powerful development process that allows us to produce a robust software product in a very short period of time!
