My Node. js learning path (4) -- unit test and node. js unit test

NPM installation:

Npm install nodeunit-g

Supports command line and browser running. Various assertions. In node. js, modularize the method to export exports. If it is an object to export module. exports, the module is the basis of the unit test. See the following node. js code:

var fs = require('fs'),global=require('./global.js');var utils = {startWith: function(s1, s) {if (s == null || s == "" || this.length == 0 || s.length > this.length)return false;if (s1.substr(0, s.length) == s)return true;elsereturn false;return true;},/* Generate GUID */getGuid: function() {var guid = "";for (var i = 1; i <= 32; i++) {var n = Math.floor(Math.random() * 16.0).toString(16);guid += n;}return guid;},/* add log information */writeLog: function(log) {if(!log) return;var text = fs.readFileSync(global.logFile, "utf-8"),_newLog = text ? (text + "\r\n" + log) : log;fs.writeFile(global.logFile, _newLog, function(err){if(err) throw err;});}};exports.utils=utils;

./Global. js is a local global variable file. Now we use NodeUnit to test the node. js code for the above Code:

var utils=new require('./utils.js');this.TestForUtils = {'TestgetGuid': function (test) {var guid=utils.utils.getGuid();test.ok(!!guid, 'getGuid should not be null.');test.done();},'TestWritelog': function (test) {var flag=false;utils.utils.writeLog("test message");flag=true;test.ok(flag,'writeLog');test.done();},'TestStartWithWords': function (test) {var name="ad_123";test.ok(utils.utils.startWith(name, "ad_"),"startwith method should be ok");test.done();}};

Test. OK is also a general asserted. You can also use node-inspector to debug the unit test program of NodeUnit.

How to Learn nodejs

First, you must understand the basic syntax, that is, javascript;
It would be better if there is a web Programming Development Foundation.

Read more information on the official website, and there are also good entry-level online tutorials abroad, such as nodebeginner.org

After a general understanding of the overall structure, you can access some common modules, such as express.
