使用SLIM编写使用Python的Fitnesse测试

Question

I downloaded and ran the fitnesse-standalone to test how does the SLIM protocol work.

Below is the directory structure

/Users
   |
    -redmont
         |
          -fitnesse-standalone.jar
         |
          -Calc.py
         |
          -FitNesseRoot/

FitNesse Wiki

!contents -R2 -g -p -f -h

!This is a test page

!define TEST_SYSTEM {slim} 
!define SLIM_VERSION {0.1}
!path /Users/redmont/Calc.py
!path /Users/redmont/fitnesse-standalone.jar
!define COMMAND_PATTERN {python -m waferslim.server --syspath 8080}

from waferslim.converters import convert_arg, convert_result, YesNoConverter

class MyCalc(object):
    """

    """
    def __init__(self):
        """

        self._A = 0
        self._B = 0
        self._multiply = 0

    @convert_arg(to_type=int)
    def setA(self, A):
        """
            Decorated method to the variable 'a' as an int.
            The decorator uses the implicitly registered int converter to 
            translate from a standard slim string value to an int. 
        """
        self._A = A

    @convert_arg(to_type=int)
    def setB(self, B):
        self._B = B

    @convert_result(to_type=str)
    def multiply(self):
        return self._A * self._B

I start the fitnesse-standalone using java -jar fitnesse-standalone.jar -p 8080 -v

The logs in the terminal are

Read Slim Header: >Slim -- V0.4<
Got Slim Header: Slim -- V0.4, and Version 0.4

When I run this fixture in FitNesse with debug, I get the following error:

Could not invoke constructor for MyCalc[0]
1 The instance decisionTable_1.setA. does not exist 
2 The instance decisionTable_1.setB. does not exist 
2 The instance decisionTable_1.multiply. does not exist

I am unable to understand why isn't FitNesse able to find my fixture code?

Is it because of some permission?

I have also installed waferslim using its egg from cheese shop.

重新安装waferslim可以解决我的问题。
