Hi
I can’t get heckle working. In fact, I’ve built an example so simple
that it either shows a bug, or I am being really, REALLY stupid.
Heckle does not appear to support RSpec directly, so I’m trying to use
spec --heckle (RSpec trunk as of 10 mins ago, Heckle 1.4.1). I’ve
constructed this pair of sample files:
18> ~/Desktop/heckle_test % cat lib/cow.rb
class Cow
def moo
“moo”
end
end
19> ~/Desktop/heckle_test % cat spec/cow_spec.rb
require ‘rubygems’
require ‘spec’
require File.dirname(FILE) + ‘/…/lib/cow.rb’
describe Cow do
it “should moo when sent :moo” do
cow = Cow.new
# cow.moo.should == “moo”
end
end
So, my thinking is, the spec should pass (nothing in the one example
to make it fail). Then heckle should change “moo” to “dfhgd5rgvsev”
or some other randomness, then it should expect “Cow should moo when
sent :moo” to fail, which of course it won’t, because I commented
out the line that checks that.
Also, if I manually violate the example, spec proceeds to heckle anyway:
25> ~/Desktop/heckle_test % spec --heckle Cow spec/cow_spec.rb
F
‘Cow should moo when sent :moo’ FAILED
./spec/cow_spec.rb:9:
Finished in 0.00767 seconds
1 example, 1 failure
*** Cow#moo loaded with 1 possible mutations
1 mutations remaining…
No mutants survived. Cool!
What’s going on? None of this is behaviour I expect.
