Need help with Add mocha testing code (describe and it) in the test\converter.js and test\server.js files to test the added new code above.

Test converter.js:

var expect = require("chai").expect; var converter = require("../app/converter");

describe("Color Code Converter - stand alone test", function() { describe("RGB to Hex conversion", function() { it("converts the basic colors: red, green, blue", function() { var redHex = converter.rgbToHex(255, 0, 0); var greenHex = converter.rgbToHex(0, 255, 0); var blueHex = converter.rgbToHex(0, 0, 255);

expect(redHex).to.equal("ff0000"); expect(greenHex).to.equal("00ff00"); expect(blueHex).to.equal("0000ff"); }); });

describe("Hex to RGB conversion", function() { it("converts the basic colors: red, green, blue", function() { var red = converter.hexToRgb("ff0000"); var green = converter.hexToRgb("00ff00"); var blue = converter.hexToRgb("0000ff");

expect(red).to.deep.equal([255, 0, 0]); expect(green).to.deep.equal([0, 255, 0]); expect(blue).to.deep.equal([0, 0, 255]); }); }); describe("", function(){ it("converts ", function(){ }); }); describe("", function(){ it("converts", function(){ }); }); });

Test Server.js:

var expect = require("chai").expect; var request = require("request");

describe("Color Code Converter - web service version", function() {

describe("RGB to Hex conversion - http://localhost:3000/rgbToHex?red=255&green=255&blue=255", function() {

var url = "http://localhost:3000/rgbToHex?red=255&green=255&blue=255";

it("returns status 200", function(done) { request(url, function(error, response, body) { expect(response.statusCode).to.equal(200); done(); }); });

it("returns the color in hex", function(done) { request(url, function(error, response, body) { expect(body).to.equal("ffffff"); done(); }); });

});

describe("Hex to RGB conversion - http://localhost:3000/hexToRgb?hex=00ff00", function() { var url = "http://localhost:3000/hexToRgb?hex=00ff00";

it("returns status 200", function(done) { request(url, function(error, response, body) { expect(response.statusCode).to.equal(200); done(); }); });

it("returns the color in RGB", function(done) { request(url, function(error, response, body) { expect(body).to.equal("[0,255,0]"); done(); }); }); });
