What is the difference between unit testing and component testing?

Unit testing focuses on testing individual functions or methods in isolation, while component testing evaluates the behavior of a group of related functions or components together.

Can you give me examples of each type of testing?

Sure! An example of unit testing is testing a single function that calculates the sum of two numbers. Component testing might involve testing a user interface component that includes multiple functions, like a form that validates input and submits data.

Which one should I prioritize in my development process?

It's generally recommended to prioritize unit testing first, as it helps catch bugs early in the development process. Component testing is also important, especially for ensuring that integrated parts work together correctly.

Are there any tools you recommend for these tests?

For unit testing, popular tools include JUnit for Java and Jest for JavaScript. For component testing, you might consider using tools like React Testing Library or Cypress.
