What is the difference between TDD and BDD in Angular?

What is the difference between TDD and BDD in Angular?

TDD, or Test-Driven Development, focuses on writing tests before the actual code, ensuring that the code meets the requirements. BDD, or Behavior-Driven Development, emphasizes collaboration between developers, QA, and non-technical stakeholders to define the behavior of the application through examples.

Can you give me an example of TDD in Angular?

Sure! In TDD, you would start by writing a test for a component, say a login form. You write a test that checks if the form is valid when the correct credentials are provided. Then, you implement the form logic to make the test pass.

How does BDD work in Angular?

In BDD, you would write scenarios in a language like Gherkin that describe how the application should behave. For example, you might write a scenario for a user logging in, detailing the steps and expected outcomes. This guides the development process.

Which approach is better for Angular projects?

It depends on your project needs. TDD is great for ensuring code quality, while BDD is beneficial for aligning development with business requirements. Many teams use a combination of both.
