浅谈Fitnesse测试框架 （二）

  Fitnesee测试框架中有两个不同的测试方法，Slim和Fit。在工作中发现两者有不同的使用用途和方法。只有分析清楚了两者的区别和共同之处，才能选择出正确的测试方法来提高工作效率。
  Fitnesse的默认测试方法是Fit,要使用Slim进行测试的话，需要在测试Page中指定
  !define TEST_SYSTEM {slim} 我们可以把TEST_SYSTEM理解为系统变量。当然我们也可以用Define来定义一些用户自己的变量，这个就以后再写了。
  Fit方法会从Fitnesse得到传来的Html文件，解析后和Fixture关联来执行Case，而Slim直接从Fitnesse中得到Html中的内容，因此Slim更加的轻便，有更好的独立性。
  每一个测试类型都有自己对应的TestTable类型

  Slim的TestTable如下
 

Decision Table	Supplies the inputs and outputs for decisions. This is similar to the Fit Column Fixture
Query Table	Supplies the expected results of a query. This is similar to the Fit Row Fixture
Ordered query Table	Supplies the expected results of a query. The rows are expected to be in order. This is similar to the Fit Row Fixture
Script. Table	A series of actions and checks. Similar to Do Fixture.
Table Table	Whatever you want it to be!
Import	Add a path to the fixture search path.
Comment	A table that does nothing.
Scenario Table	A table that can be called from other tables.

  Fit的TestTable如下

ColumnFixture	This is the style. you may end up using most: rows of data represent inputs and expected outputs.
RowFixture	This is good for testing queries that should return an exact set of values (order-independently).
ActionFixture	This style. allows you write a script. that emulates a series of events (such as controls manipulated on a user interface).
Comment Tables	Sometimes you want a tablular comment that is not executed as a test.

   两者有相似的几个TestTabel 如Decission Table对应ColumnFixture等等。

   Fit接受输入Null代表空指针，Blank代表空的字符串，而Slim不接受，因此对于Slim的输入，我们需要写一个Converter来进行转换。类似于

public String converter(String input)
   if(input.equals("null")
       return null;
   else if (input.equals("blank"))
       return "";

这样也就解决了转换的问题。

很晚了，睡觉去了，明天继续研究Fitnesse
