When JavaScript first appeared in 1995, its main purpose was to handle some of the input validation that had reviously been left
2、to server - side languages such as Perl. Prior to that time, a round - trip to the server was needed to determine if a required field had been left blank or an entered value was invalid. Netscape Navigator sought to change that with the introduction of JavaScript. The capability to handle some basic
3、 validation on the client was an exciting new feature at a time when use of telephone modems was widespread. The associated slow speeds turned every trip to the server into an exercise in patience. Since that time, JavaScript has grown into an important feature of every major web browser on the mark
4、et. No longer bound to simple data validation, JavaScript now interacts with nearly all aspects of the browser window and its contents. JavaScript is recognized as a full programming language, capable of complex calculations and interactions, including closures, anonymous (lambda) functions, and eve

JavaScript has become such an important part of the Web that even alternative browsers, including those on mobile phones and those designed for users with disabilities, support it. Even Microsoft, with its own client - side scripting language called VBScript, ended up including it

The rise of JavaScript from a simple input validator to a powerful programming language could not have been predicted.

They are written in all kinds of languages, they run on every kind of operating system, and they behave in every conceivable way.
11、At the core of every web application is the fact that all of its functionality is communicated using HTTP, and its results are typically formatted in HTML. Inputs are communicated using GET, POST, and similar methods. Lets explore each of these things in turn. Our definition of a web application is
12、simply any software that communicates using HTTP. This may sound like a broad definition, and it is. The techniques we are showing you in this book apply to any technology based on HTTP. Notice that a web server that serves up static web pages does not fit our bill. There is no software. If you go t
13、o the same URL, you will see the exact same output, and there is no software that executes as a result of making the request. To be a web application, some kind of business logic (script, program, macros, whatever) must execute. There must be some kind of potential variability in the output. Some de

These technologies include win32 technologies, J2EE,CORBA, and CGI scripting. The major difference between these technologies and the ne

This new breed of technology is based on standardized XML (as opposed to a proprietary binary standard) and supported globally by most major technology firms. XML provides a language-neutral way for representing data, a

22、ectly.Unit tests are typically fairly low-level and modular ideally, you should be able to execute a unit test in isolation, and not depend on any other test cases to be run beforehand. In other words, your tests should be able to be executed in any order, or individually, and still work correctly.
23、Another important best practice regarding unit tests is that unit test should leave the system in the same state as it was in before the test. For example, if you are testing a DAO class, your tests may well insert, update, and delete data in the database, but once the test has finished,the database
24、 should be in the same state as before the test was started. This is not always easy,as a failed test may well leave your environment in an unstable state. Developers often need to write special code (generally known as fixture code) designed to set up a clean testenvironment before testing and to t
25、idy up afterward. Although it is possible to write unit tests entirely from scratch, unit testing frameworks make things at lot easier. By providing a simple, well-understood framework in which to write your tests, libraries such as JUnit and TestNG let developers concentrate on writing high quality
26、 unit tests. Testing frameworks also make it easier to organize your tests, to selectively run individual tests, to report on test results, and to write supporting fixture code. 单元测试主要涉及写作测试用例来确保你的类功能正确。单元测试是典型的相当低 ,modular-ideally,你应该能够执行单元测试孤立进行的 ,不依赖于任何的其它测试用例被预先运行。在其他的话 ,你的测试应该能够执行任何订单 ,或单独使用 ,也
27、还在工作正确。 另一个重要的最佳实践 ,关于单元测试是单元测试应该离开系统同一国家在测试前。例如 ,如果你正在测试的一把刀 ,班 ,你的测试可能插入 ,更新 ,删除数据的数据库 ,但是一旦测试已经结束了 ,数据库应在同一国家在考试之前就开始了。这是不容易 ,作为一个考试不及格很可能离开你 的环境不稳定的状态。开发商通常需要写特别代码 (通常称为 “ 夹具代码 ”) 旨在建立一个干净的测试环境在测试和整理之后。尽管可能会写单元测试完全从零开始 ,单元测试框架使事情变得容易很多。通过提供一个简单、明了的结构来写你的测试、图书馆如 JUnit和挑选让开发商集中精力写作高质量的单位测试。测试框架也能很
