http://mochajs.org/ is a testing framework in JavaScript. This is a minimal implementation of asynchronous mocha api. Clone the repository and then run npm install to setup install dependencies. Run npm start to test the current implementation. It should produce output similar to ‘output.txt’. The code supports asynchronous tests, in which case, the done callback has to be passed into the test case and called once all tests are complete.

In code terms, current implementation allows for synchronous tests written as:

    test('should test ![] === true ', () => {
      assert.equal(![], true);
    });

It also has asynchronous tests capabilites, written as below:

    test('should test ![] === true ', (done) => {
      setTimeout(() => {
        try {
          assert.equal(![], true);
          done(); // success case
        } catch (err) {
          done(err); // error case
        }
      }, 2000);
    });

The timeout can be set using the following code:

    settings.timeout = 5000;
