#Mocha
Mocha is a testing library for Node.js, created to be a simple, extensible, and fast testing suite, making asynchronous testing simple and fun. Mocha tests run serially, allowing for flexible and accurate reporting, while mapping uncaught exceptions to the correct test cases.
This repo shows its usage by implementing a color converter that can translate from RGB (red, green, blue) to hexadecimal color representation. As well as creating a web server that exposes the above converter, and demonstrates how to test asynchronous code.
Mocha Repository: https://github.com/mochajs/mocha
Source: https://semaphoreci.com/community/tutorials/getting-started-with-node-js-and-mocha
##Installation
Install with npm:
```
$ npm install mocha
```
##Usage
We will update the test command in package.json to contain the following command.
```json
{
"scripts": {
"test": "mocha test/mocha.js"
}
}
```
In order to run the tests simply execute
```
$npm test
```
##Syntaxis
###describe
Describe the features that we are implementing by giving us a describe function that encapsulates our expectations.
```javascript
describe("Feature", function() {
});
```
###it
The it function is very similar to the describe function, except that we can only put expectations in the body of the it function.
```javascript
describe("Feature", function() {
it("Expectation", function() {
});
});
```
#####done
For every it that needs to wait for a response value, inject a done callback function and call it only when the expectations were executed.
```javascript
var expect = require('chai').expect;
var request = require('request');
//...
describe("Feature", function() {
it("Expectation", function() {
request(url, function(error, response, body) {
//Expectation
done();
});
});
});
//...
```
