Comments on Mock-Based Testing

where the amazing happens — Sun, 04 Jun 2006 10:53:00 GMT

很好的一��文章，深入说了很多关于��试的东�ѝ�?br />
A article from Technoetic
- Posted in Software Dev., Agile by Steve Bate

I recently read a blog entry with criticisms of mock-based testing. The author raised several “issues�?with using mocks to support unit testing. I’m commenting here since the author has closed comments on the original blog entry.

Issue 1: Poor integration tests, as everything is being tested in isolation

I’ve had good experience with mock-based testing. However, it’s obvious that mocks will only test classes in isolation. I use both unit tests and integration tests (sometimes called system or acceptance tests) together. The need for integration tests is not an issue for mock-based techniques and is not a good reason to use less mocks. It’s just a different aspect of testing. A more common issue in my experience is that people in the agile community who are new to testing often don’t understand these different aspects of testing and seem to believe that mock-based unit testing and integration testing are mutually exclusive options. The lack of common terminology in the community only worsens the problem. For some people, a “unit�?is a class or small group of tightly coupled classes. For others, it’s a large portion of the software product. Most agile developers seem to call every test they write a unit test. It’s become so confusing for some teams that I’ve seen terminology like “integration unit tests�?being used to describe testing strategies.

But, back to the topic. Poor integration testing is simply the result of lack of integration tests. Mocks do not cause a lack of integration tests. A team makes that choice, probably based on a weak understanding of the tradeoffs between isolation (unit) and integration (system) testing.

Issue 2: Mocks add complexity to the software design.

“I’ve seen numerous occasions where the introduction of mocks has added a large amount of complexity to an otherwise simple design. This complexity leads to higher implementation costs, a higher cognitive load on the developers working on the system, and higher maintenance costs (as there’s more code to maintain). �?/p>

The author appears to focused on the increased use of interfaces when using mock-based testing and expresses the opinion that interfaces should only be used where we’d want to be able to replace one implementation with another. First, there are other reasons to use interfaces. In general, interfaces are useful for managing dependencies between software components or subsystems. This can be beneficial even if the implementations do not change (see The Dependency Inversion Principle).

A modular software design will generally make it easier to use mock-based testing without altering the design specifically for the mocks. However, there are times when the software must be modified to support testing. Fortunately, the changes needed to support testing often, if done well, support the modularity goal.

In my experience, extra interfaces don’t add a significant maintenance overhead. Most effort is spent implementing the interface. The time writing the interface itself (or extracting it using an IDE’s refactoring tools) is negligible.

My Conclusions

In almost every case, I see the “simplicity�?gained by not using mocks overshadowed by complex test setups to initialize large groups of dependent objects. The dark side of integration testing is that it’s often very slow for large numbers of tests. Some teams are using continuous integration tools like Cruise Control to run their “unit tests�?(usually they are actually integration tests). This delays the feedback about broken builds but is often necessary because the tests run so slow. I realize there other reasons for using CC, but this is a common one from what I’ve seen and heard.

I’ve worked on teams where we had thousands of tests that ran in less than 15-20 seconds total on a developer workstation. This was a direct result of heavy use of mock-based testing. We also had a slower suite of integration tests that required 4-5 minutes to run. We didn’t need a continuous integration server because we were able to integrate and run our unit tests before every commit to the source control system. The team integrated 10-20 times/day and broken builds were practically nonexistent over the several years I worked with them. In the very rare cases when the build did break, it was typically fixed in a matter of minutes.

The other benefit of the isolation testing enabled by mocks is the ability to pinpoint problems much more quickly. It’s a form of the divide and conquer problem solving strategy, only the divide part is already done. The conquering is relatively easy compared to tracking down the cause of test failures when many classes are being exercised in a test.

My experience was that our mock based unit tests caught about 98% of the code problems before the code was ever committed to source control. The integration tests caught about another 1% beyond that (almost always because of a flaw in the mock-based testing) and manual testing caught the other 1%.

TODO:
�l�箋��试和改�q?不满意的地方:@ToSession标签

更新日志:

2006-06-18 增加和改�q?@ToList 标签,用来修饰一个参��Cؓjava.util.List的setter�Ҏ��
2006-05-23 增加 VelocityView接口,方便velocity视图调用.

2006-05-22 增加 5.1 初始�?velocity
2006-05-21 增加 4.1 - 4.2 HttpSession操作

更新note:
1.HttpServletRequest�?a href="file:///D:/jakarta-tomcat-4.1.30/servlet%20api/javax/servlet/ServletRequest.html#getParameterNames()">getParameterNames() �Ҏ��q�回的Enumeration相对于页面参数的物理��序刚好是相反的,所以实现@ToList标签时候需要先用一个Stack来对所有参数进行反�?不知tomcat在这个api�Ҏ��上是怎么实现�?��Z��么就倒过来。c语言函数可以�Ҏ��不同的call�c�d��来指定不同的压栈的顺序，莫非�q�个惯例也被用到servlet里面来了�Q�挺有意思的东西�Q�看来需要留意一下�?br />

问题和解��x��?

1.关于@ToSession标签.如果是登陆的�?那么��有个判断条件决定某个login token是否应该被加到session�?�q�时候可以在@ToSession标记的getter�Ҏ��中加入逻辑判断,来决定返回一个token实体或者null(�q�样做有点古�?.).

2.路径的问�?比如一�?a href="http://host/logic/bbs/admin/ListUsers.wff">http://host/logic/bbs/admin/ListUsers.wff 摸版的相兌��源目�?比如,囄��,css,js�{?��必��d��在webproject/bbs/admin响应的目录下,有点像struts的多模块.

开�?

Ruby on Rails有个设计思想是用�~�码规定代替�J�琐的配�|�文件。jvm�q�_��已经有一些类似ror的实玎ͼ�比如
grails(http://docs.codehaus.org/display/GRAILS/2006/03/29/Groovy+on+Rails+(Grails)+0.1+Released)

虽然�׃��java自��n的局限，它很隑ց�出像ruby或者groovy那样动态语�a�那样随心所�Ʋ的动作�Q�但是利用它的运行时反射、动态代理等�Ҏ��来��可能实现“用�~�码规定代替�J�琐的配�|�文件”这一思想�?br />下面转入正题�?/p>

ServletAPI对HTTP协议�q�行了封�?通过配置Web.xml来把不同的请求�{发给不同的servlet来处理。Web框架则用一个ActionServlet�Q�根据自��q��对Action的定义来转发��h��?br />抛开那些�J�琐的配�|�文�Ӟ��设想一下这样一�U�方�?

1.Web动作的处理和响应

假设�q�样一个POST��h��:

Web动作实现Bean:
org.qqsns.web.logic.group.NewTopic
注意后面的logic/group/NewTopic和logic.group.NewTopic, 动作�c�d��Web动作是通过��h��路径和包名相互关联�?br />�q�样�Q�对Web动作的响应就依赖于编译期的代码的�l�织�l�构而不是执行期的配�|�文件。这��L��好处是避免了�l�护�J�琐的配�|�文�?特别是在没有IDE支持的情况下�?/p>

org.qqsns.web.logic.group.NewTopic�c�L��一个实现net.wff.servlet.WebAction接口的POJO�Q�下面是NewTopic中execute的方法片�D?

//Only method must be implemented for interface net.wff.servlet.WebAction
public String execute(WebParam param, VelocityView view)
throws ServletException, IOException{
  ...
  //return "redirect /success.html"; //��h��重定�?br />  return "/success.jsp";              //��h��转发
}
execute�Ҏ��的返回值手动指定了一个�{发或重定向的路径�?/p>

2.输入验证

普通的Web框架都带数据输入验证功能,一般复杂程度和功能强大与否成正比�?br />�q�里��单地要求从setter�Ҏ��里抛��Z��个包含验证信息的异常�Q�以此来实现输入异常处理�?br />
普通setter�Ҏ��
public void setName(String name){
this.name = name;
}

��d��输入验证后的setter�Ҏ��

public void setName(String name) throws InputException{
if(name.length()<3)
    throw new InputException("Topic name must has a length greater than 3");
  this.name = name;
}

在WaterFallServlet如何中处理验证信�?

    WebAction wa =
    (WebAction)Class.forName(classPath).newInstance();
          //procces forwarding
          try {
    ActionHelper.setProperties(request,wa);
   } catch (InputException e) {
    //return to input view
    //header:referer
    String rtn = request.getHeader("referer");
    //clear old errors
    if(rtn.indexOf("?")!=1){
     rtn = rtn.substring(0,rtn.indexOf("?"));
    }
    rtn=rtn+"?error="+URLEncoder.encode(e.getMessage(),"UTF-8");
    response.sendRedirect(rtn);
    return;
   }

�q�样验证信息通过��h��参数传回到输入页�?

3.数据�l�定

假设有这��L��html输入:

下面是NewTopic中execute的方法全�?

public String execute(WebParam param, VelocityView view)
throws ServletException, IOException{
  System.out.println(getName());
  System.out.println(getNumber());
  System.out.println(getPrice());
  System.out.println(getLength());
  return "/success.html";
}

自动从request注入parameter,�q�也是Struts DynamicActionForm的好处之一�?br />不过�q�里实现更类似多了类型�{换的
因�ؓName的类型是String,Number的类型是Integer,Price的类型是float,length的类型是double.至于其他复杂的类�?也许jsf的�{换器是个更好的主意�?br />�q�样��初步解决了数据的输入绑定和验证。余下的��是业务逻辑的问题�?/p>

4.如何操作Session中的信息

获取session中的信息:

@FromSession(
     sessionKey=User.key
     )
public void setCurrentUser(String currentUser) {
  this.currentUser = currentUser;
}

信息保存到session�?

@ToSession(
      sessionKey = User.key
    )
public String getName() {
  if(login())return name;
  else return null;
}

�q?个方法定义在WebAction的实现类中�?br /> 框架在execute()之前执行@FromSession动作�Q�在execute()之后执行@ToSession动作�?br /> �q�里使用了annotation,所以要求必��L��jdk5.0以上版本.

5.1 Velocity
waterfall启动时候自动在WEB-INF目录下寻扑�ƈ初始化Velocity.properties文�g
操作:
public String execute(WebParam param, VelocityView view)
throws ServletException, IOException{
view.addElement("msg","Hello");
view.go("index.vm");
return null;
}

           // procces forwarding
           try {
    ActionHelper.setProperties(request,wa);
   } catch (InputException e) {
     // return to input view
     // header:referer
    String rtn = request.getHeader( " referer " );
     // clear old errors
     if (rtn.indexOf( " ? " ) != 1 ) {
     rtn = rtn.substring( 0 ,rtn.indexOf( " ? " ));
    }
    rtn = rtn + " ?error= " + URLEncoder.encode(e.getMessage(), " UTF-8 " );
    response.sendRedirect(rtn);
     return ;
   }

�q�样验证信息通过��h��参数传回到输入页�?

3.数据�l�定
