To write a test case in Mocha, you can follow these simple steps:

1. Install Mocha globally by running the following command in your terminal:

1

npm install -g mocha

1. Create a new test file (e.g., test.js) and require Mocha and any other necessary modules at the top of the file:

1
2

const assert = require('assert');
const { describe, it } = require('mocha');

1. Write your test case(s) using the describe and it functions provided by Mocha:

1
2
3
4
5
6

describe('MyFunction', function() {
  it('should return true', function() {
    // Write your test code here
    assert.strictEqual(myFunction(), true);
  });
});

1. Run your test file using the Mocha command in the terminal:

1

mocha test.js

1. You should see the test results in the terminal output, indicating whether the test cases passed or failed.

By following these steps, you can easily write and run test cases in Mocha for your JavaScript code.
