我眼中的开发和��试

paulwong — Mon, 01 Dec 2014 12:55:00 GMT

摘要�Q�在IT行业�Q�开发和��试之间的关�p�M��直是一个大家��|�z�乐道的话题。那在周兆熊��g��Q�开发和��试是什么样的？他进行了�l�致的说明，�q�就两者的关系�l�出了一些徏议�?nbsp;
在IT行业�Q�开发和��试之间的关�p�M��直是一个大家��|�z�乐道的话题。在整个软�g产品的生命周期中�Q�开发和��试人员所做的工作分别对应不同的阶�D�，如图1所�C��?nbsp;

�? 开发和��试人员的分�?/div>
工作内容

从图1可以看出�Q�开发和��试是一个上下游的关�p�R�?nbsp;

具体而言�Q�开发�h员主要做�q�几件事情：

�W�一�Q�对软�g需求说明书�q�行详细评审�Q�弄清楚要开发一个什么样的��Y件�?nbsp;

�W�二�Q�编写��Y件详�l�设计、单元测试和集成��试规程文档。��Y件详�l�设计文档是最重要的文档，在里面，要写清楚自己�E�序的流�E�、函数设计、异�怿�护考虑�{�。在动手写程序之前，一定要��Y件详�l�设计文档写好，�{�评审通过了再写代码�?nbsp;

�W�三�Q�编写代码，用程序实现��Y件的功能。很多�h认�ؓ的��Y件开发就是写代码�Q�其实这是一�U�很狭隘的理解，写代码在整个开发流�E�中�Q�只占了很小的部分�?nbsp;

�W�四�Q�程序写好之后，开发�h员要对它�q�行单元��试和集成测试也叫（自测�Q�，��保�E�序的正��性。这里就出现�?#8220;��试”二字�Q�但与��Y件测试所做的“��试”是不同的�Q�他们做的是“�pȝ��试”。等自测通过之后�Q��ƈ且相��x��档也写好之后�Q�就可以提交�E�序版本�Q�供��试人员�q�行��试了�?nbsp;

相对开发，��试人员主要做这几�g事情�Q?nbsp;

�W�一�Q�参与��Y仉��求说明书的评审，对��Y件要实现的功能有一个大致的了解�?nbsp;

�W�二�Q�搭建测试环境。这个是很重要的�Q�也是比较难的事情。什么是“��试环境”呢？��是��_��不管什么��Y�Ӟ��都有个运行的条�g�Q�如操作�pȝ��c�d��、参数设�|�及配套软硬件设施等�Q�这些统�U�Cؓ“环境”。�ؓ了保证程序功能的正确性，要在软�g发布之前�Q�尽量模拟��Y件实际的�q�行环境�Q�这��是搭徏��试环境时要做的事情。很多��Y件在正式商用之后出问题，��是��试的时候没有还原现场环境所致�?nbsp;

�W�三�Q�对软�g�q�行�pȝ��试�q�输出测试报告。所谓系�l�测试，��是指将配套的所有��Y仉��q�行��h��Q�看一下所有的功能是否正常。当出现问题的时候，要及时和开发�h员联�p�，以修正��Y件缺陗��?nbsp;

�W�四�Q�指导现��Z�h员安装��Y件程序，�q�在必要的时候亲自出差到现场��d��装��Y件。因此，��试人员也可能会�l�常出差的�?nbsp;

“三��鼎立”

开发�h员的主要��d��是用�E�序完成软�g需求，而测试�h员的主要��d��则是保证�E�序功能的正��性，他们做事的依据都是需求开发工�E�师�~�写的需求说明书�?nbsp;

在实际的软�g开发项目中�Q�需求开发工�E�师、��Y件开发工�E�师和��Y件测试工�E�师之间的交��是很频�J�的�Q�如�?所�C��?nbsp;

�? 三类角色�?#8220;三��鼎立”

��像“三国时期”的魏蜀�?#8220;三��鼎立”一��P��需求开发工�E�师、��Y件开发工�E�师和��Y件测试工�E�师所站的立场不同�Q�对软�g的认识也不同。大安��要相互讨论、协商，挑选出一套最佳的软�g实现�Ҏ��?nbsp;

一些徏�?/strong>

在完成��Y件研发的�q�程中，开发和��试之间的关�p�非常的“微妙”�Q�时而合作如亲�h�Q�时而争论如敌�h。我认�ؓ�Q��ؓ了做出高质量的��Y件��品来�Q�开发和��试需要做刎ͼ�

�W�一�Q�共同参与��Y仉��求文档的评审�Q�对�E�序要实现的功能有一个清晰的认识。如果对需求有疑问�Q�一定要当面提出来�?nbsp;

�W�二�Q�在寚w��求达成共识之后，软�g开发�h员严格按照��Y仉��求文档上的描�q�来�~�写�E�序�Q�如果在�E�序实现上有困难�Q�要提出来和大家讨论。��Y件测试�h员严格按照需求的描述来验证程序的功能�Q�如果发现程序实��C��需求不�W�，要及时与软�g开发�h员联�p�，大家共同��程序问题解��x��?nbsp;

�W�三�Q�如果开发时间紧张、�h手不��I��那么在开发�h员编写程序的时候，��试人员可以帮忙把测试环境搭建好。等�E�序�~�写好之后，开发�h员便可以立即�q�行单元��试和集成测试�?nbsp;

�W�四�Q�不��是需求有问题�Q�还是程序有�~�陷�Q�大安��可以指出来。但注意要就事论事，不可��Y仉��题上升�ؓ对特定个人的��n��d��?nbsp;

�W�五�Q�虽然是各司其职�Q�也许还�w�处不同的部门，但大家的共同目标是一致的�Q�做��客户满意的、高质量的��Y件��品。开发和��试人员要�ؓ了这个目标，一起努力�?nbsp;

�l�束�?/strong>

一个��Y件��品的成功需要从各个环节上去把握�Q�因此用人的左手和右手的关系来比��d��发和��试之间的关�p�L��为恰当。好的��Y件��品需要开发和��两手抓�Q�两手都要硬�?nbsp;

单元��试、集成测试和�pȝ��试的不同之处[转]

paulwong — Fri, 21 Nov 2014 01:09:00 GMT

首先�Q�他们的��试�Ҏ��不同�Q?br />
单元��试属于白盒��试�Q?br />
集成��试属于灰盒��试的范��_��

�pȝ��试属于黑盒��试�?br />

其次�Q�他们的考察范围不同�Q�也��是他们��试的重点不同：

单元��试主要��试单元内部的数据结构、逻辑控制、异常处理等�{�；

集成��试主要��试模块之间的接口和接口数据传递的关系�Q�以及模块组合后的整体功能；

�pȝ��试主要��试整个�pȝ��相对于需求的�W�合度�?

再次�Q�他们的基准不同�Q?br />
单元��试评估的主要是逻辑覆盖率；

集成��试评估的主要是接口覆盖率；

�pȝ��试评估的是��试用例寚w��求规格的覆盖率�?img src ="http://www.aygfsteel.com/paulwong/aggbug/420382.html" width = "1" height = "1" />

Watij and Maven

paulwong — Tue, 03 Jan 2012 14:08:00 GMT
By the way, I did this "by hand" and got it working.

First, download the waitj bundle and unzip it.

Then, use maven to manually install each dependency in the lib folder
like so:
mvn install:install-file -Dfile=webspec.jar -DartifactId=webspec -
DgroupId=watij -Dversion=1.3.1 -Dpackaging=jar

You can also do deploy:deploy-file if you want to put them into a
central maven repo.

Of course, you don't need to do this for log4j, junit, slf4j. I did
it for all the others for speed, registering them under "watij" and
version 1.3.1

Got this working in Eclipse, a simple login test case, yipee!

Here is the POM snippet for my project:
