Hash_include with regular expression

I’m trying to match a string in a hash passed to :find using a regular
expression since I don’t want to know all the other details of
the :conditions passed to find. I’ve tried variations on the
following with no success, e.g., not using hash_including and putting
both hashes into a single hash_include.

c = /.a.snapshot_id = 1./
SomeClass.should_receive(:find).with(:all,
hash_including(:conditions=>c),
hash_including(:include=>’’)).and_return([mock_class])

The rspec fails with the following:
expected: (:all, hash_including(:conditions=>/.da.snapshot_id =
1.
/),
hash_including(:include=>""))
got: (:all, {:conditions=>" a.snapshot_id = 1 OTHER CRITERIA…
“, :include=>”"})

hash_including doesn’t evaluate regexps because you might actually be
assigning a regexp to a key in a hash:

foo.should_receive(:bar).with(hash_including(:exp => /match me/))

foo.bar(:a => 1, :exp => /match me/)

You can, however, pass a block to should_receive (or stub) and rspec
will pass it the arguments it gets. For example:

SomeClass.should_receive(:find) {|scope, options|
scope.should == :all
options[:conditions].should match(/.a.snapshot_id = 1./)
}

SomeClass.find(:all, :conditions => “a.foo = ‘bar’ and a.snapshot = 1”)

Off topic, but if you’re using a more recent version of rails (not
sure when this was introduced), the convention is SomeClass.all
instead of SomeClass.find(:all). That would simplify the expectation a
bit:

SomeClass.should_receive(:all) {|options|
options[:conditions].should match(/.a.snapshot_id = 1./)
}
