Decaf

This package provides a SliM server implementing the FitNesse SliM protocol. It allows you to write test fixtures in CoffeeScript or JavaScript, and invoke them from a FitNesse test.

Setup

Put these commands in a parent of the Decaf test pages.

!define TEST_SYSTEM {slim}
!define COMMAND_PATTERN {decaf %p}

Possible ES6 class support?

I have been creating my Fitnesse Functions with the following syntax in JavaScript.

| import |
| logic |

|DT:logic|
|a|b|and?|
|0|0|0|
|0|1|0|
|1|0|0|
|1|1|1|

and in a JS file called logic.js

'use strict';

function logic() {}

logic.prototype.setA = function(a) {
  this.a = a;
};

logic.prototype.setB = function(b) {
  this.b = b;
};

logic.prototype.and = function() {
  return this.a & this.b;
};

module.exports.logic = logic;

I have been wanting to use ES6 classes for my fixures. Below is an attempt...

'use strict';

class logic {
  constructor() {
    //
  }

  setA(a) {
    this.a = a;
  }

  setB(b) {
    this.b = b;
  }

  and() {
    return this.a & this.b;
  }
}

module.exports.logic = logic;

However, I get the following errors

I am a little confused because the 'class' keyword is just syntactic sugar. So, perhaps my syntax is wrong.

Has anyone been able to get ES6 classes to work? If so, what syntax are you using?

Thanks

Error: Decaf.cmd not found

Followed the README instructions, installed Decaf, but am getting this error when trying to run the fixture:
Unable to start test system 'slim': java.io.IOException: Cannot run program "decaf.cmd": error=2, No such file or directory

Any ideas?

Running a test suite sometimes aborts

Hello,

running a test suite sometimes aborts if the data event is fired with only a part of the data written from the SLIM client.

Below is a possible patch. However, checking for completeness ist not perfect. isComplete should actually try to deserialize the message and only if that succeeds continue.

When running http://localhost:8080/HelloDecafTest?test i get:
Could not complete testing: fitnesse.slim.SlimError: Error SLiM server died before a connection could be established. env: coffee: No such file or directory
