Rspec2+Factory girl, how to test a change?

Hi, I'm new on tests but trying to test the following method, but it gives me an error message about "nil is not a symbol".

# job.rb

How does your factory declaration look like?

In this block: lambda { @job.publish }.should   change(@job.available).from(false).to(true) end

try putting the arguments to the change method in curly braces:

lambda { @job.publish }.should   change{@job.available}.from(false).to(true) end

If you pass the method parameters, which is what it expects with parantheses, it expects two arguments, the second of which would be the method name in the form of a symbol, which I think explains the 'nil is not a symbol' error you're getting.

By the way, if you're upgrading RSpec1 to RSpec2, there's a cheat sheet of changes here: Schneider Schreibt: RSpec 2 changes from RSpec 1
