How to setup an npm test via mocha?

To set up an npm test using Mocha, follow these steps:

1. Install Mocha globally by running the command: npm install -g mocha
2. Install Mocha as a development dependency in your project by running the command: npm install --save-dev mocha
3. Create a directory in your project for your test files, for example test.
4. Create a test file within the test directory, for example test.js, and write your test cases using Mocha's syntax. Here is an example of a simple test case: const assert = require('assert'); describe('Array', function() { describe('#indexOf()', function() { it('should return -1 when the value is not present', function() { assert.equal([1,2,3].indexOf(4), -1); }); }); });
5. Add a test script to your package.json file that runs Mocha with your test files. Modify the scripts section in your package.json file like this: "scripts": { "test": "mocha test/*.js" }
6. Run the npm test command to execute your Mocha tests: npm test

Your Mocha tests will now run and display the results in your console.
