rspec users - Feb 2007 - "should.be_in [values]" and "each_should_satisfy"

Hi!

I just started using RSpec and have some question that I couldn''t find 
answers to.

If I have a result that can have two valid values, is there a better way 
of writing
the following assertion?

[value1,value2].should_include actual

Is there a more elegant way of performing should_satisfy on a 
collection, for
example I currently use something like collection.each {|x| 
x.should_satisfy {|x| ... } }
which is very ugly. Is there something like each_should_satisfy?

Thanks,

Esad

No, but you''ll soon (0.8) be able to write your own custom expectation
matchers. So you''d be able to write, for example:

actual.should be_in(value1,value2)

There''s not. Again, when 0.8 is released you''ll be able to
right this
yourself. Probably something like:

collection.should satisfy_for_each { |x| ... }

Coming soon....
