00:11It can be used with multiple JavaScript frameworks,
00:18and in this video I will show only a small example in Next.js.
00:28In the configuration file I can specify how Jest should work in my application.
00:39For example, with this option I am explaining to Jest to ignore directories what is not my code.
00:54And I will create my first test file.
01:09To create its content, I will use the examples from the official documentation.
01:30The describe function is used to group related tests together.
01:47To run a test, I will enter the Jest command.
