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

End-to-end testing evaluates the entire application flow, while unit testing focuses on individual components.

Can you give me examples of each type of testing?

Sure! An example of unit testing is testing a single function in isolation. An example of end-to-end testing is testing a user login process.

When should I use end-to-end testing instead of unit testing?

Use end-to-end testing when you need to validate the complete user experience, while unit testing is best for checking specific functionalities.

Are there any tools you recommend for these types of testing?

For unit testing, tools like JUnit or NUnit are popular. For end-to-end testing, Selenium and Cypress are great options.
