How to test in mocha?

To test in Mocha, you can follow these steps:

1. Install Mocha globally on your system using npm:

1

npm install -g mocha

1. Create a test file, for example test.js, and write your test cases using Mocha's syntax. Here is an example of a simple test case:

1
2
3
4
5
6
7
8
9

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);
    });
  });
});

1. Run the test file using the Mocha command:

1

mocha test.js

1. You can also use different reporters to display test results in different formats. For example, you can use the "spec" reporter to display test results in a list format:

1

mocha test.js --reporter spec

1. You can also watch for file changes and automatically rerun your tests using the --watch flag:

1

mocha test.js --watch

These are some basic steps to get started with testing in Mocha. You can explore more features and options in Mocha's documentation.
