javascript - Jasmine shared specs scoping issues with coffeescript -

-

i'm attempting dry jasmine tests extracting out shared examples.

@sharedexamplesforthing = (thing) ->   beforeeach ->     @thingy = new thing    "is neat", ->     expect(@thingy.neat).tobetruthy()   describe "widget shared behavior", ->   sharedexamplesforthing(-> new widget)

this works nicely when defined in 1 file. problems i'm encountering occur when try move sharedexamples separate file. can't find variable: sharedexamplesforthing ...

so in interest of debugging, tried following:

describe "widget shared behavior", ->   "is acting meany", ->     console.log sharedexamplesforthing     expect(false).tobetruthy()   sharedexamplesforthing(-> new widget)

in is acting meany block, log shows sharedexamplesforthing [function] still can't find variable outside it. feel might have scoping issue outside of current experience, wrong that. missing here?

(using rails, jasminerice, guard-jasmine)

i found piece on shared examples thoughtbot useful.

i implemented in coffeescript follows:

1) in helper file loaded before spec files:

window.foospec =   sharedexamples: {}  window.itshouldbehavelike = (->   examplename      = _.first(arguments)   examplearguments =     _.select(_.rest(arguments), ((arg) => return !_.isfunction(arg)))   innerblock       = _.detect(arguments, ((arg) => return _.isfunction(arg)))   examplegroup     = foospec.sharedexamples[examplename]    if(examplegroup)     return describe(examplename, (->       examplegroup.apply(this, examplearguments)       if(innerblock) innerblock()       )     )   else     return it("cannot find shared behavior: '" + examplename + "'", (->       expect(false).toequal(true)       )     ) )

2) specs:

(a) can define shared behaviour:

foospec.sharedexamples["had day"] = (->   "finds code examples", ->       expect(this.thoughtbot_spy).tohavebeencalled() )

(b) , use anywhere in spec as:

itshouldbehavelike("had day")

(note: assuming spec has defined this.thoughtbot_spy accordingly before above line)
