What is the structure of a Jest test?

A Jest test typically consists of three main parts: describe, it, and expect. The 'describe' block groups related tests, 'it' defines a single test case, and 'expect' is used for assertions.

Can you give me an example of a simple Jest test?

Sure! Here's a simple example:

describe('Math operations', () => {
  it('adds two numbers', () => {
    expect(1 + 2).toBe(3);
  });
});

What are some best practices for writing Jest tests?

Some best practices include keeping tests isolated, using descriptive names, and testing edge cases. Also, ensure to clean up after tests if necessary.

How can I run my Jest tests?

You can run your Jest tests by using the command npm test or jest in your terminal, depending on your setup.
