What is the difference between unit testing and end-to-end testing?

What is the difference between unit testing and end-to-end testing?

Unit testing focuses on individual components of the software, while end-to-end testing evaluates the entire application flow.

Can you give me examples of each type of testing?

Sure! A unit test might check a single function's output, while an end-to-end test could simulate a user logging in and making a purchase.

Which one should I prioritize in my testing strategy?

It depends on your project needs. Unit tests are great for catching bugs early, while end-to-end tests ensure the whole system works together.

How do I implement unit tests in my project?

You can use testing frameworks like JUnit for Java or pytest for Python to write and run your unit tests.
