What is the structure of a Mocha test?

A Mocha test typically consists of three main parts: describe, it, and assertions. The 'describe' function groups tests, 'it' defines individual test cases, and assertions check the expected outcomes.

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

Sure! Here's a simple example:

const assert = require('assert');

describe('Array', function() {
  describe('#indexOf()', function() {
    it('should return -1 when the value is not present', function() {
      assert.strictEqual([1, 2, 3].indexOf(4), -1);
    });
  });
});

What are some common assertions used in Mocha?

Common assertions in Mocha include:

• assert.equal() for equality checks
• assert.notEqual() for inequality checks
• assert.deepEqual() for deep equality checks
• assert.throws() to test for exceptions.

How do I run my Mocha tests?

You can run your Mocha tests by using the command mocha in your terminal, assuming you have Mocha installed globally or in your project.
