Why I use Verify

I was just "specing" up my Thread Safe Wrappers when I stumbled about methods on Array I had never seen before.Eg. #taguri=. Realizing that it ( and some others ) were introduced by rspec I had a choice between a rock and a hard place: Either not using introspection in my definitions of methods in the Array wrapper (and probably the same for Hash, String and friends), or deleting those methods manually.
The first choice is just impossible because it would mean lots and lots of typing, which is just unacceptable, and the second choice would mean that there would be code in the production code which is there for the sole purpose of not implementing methods from the Rspec framework.

It occurred to me than that Verify has been written for that exact reason by YHS. Not to step on the toes of the testee!

I immediately started to rewrite my *_spec.rb files into *_verify.rb files (not that this convention is enforced by Verify but it seems good practice ;). And it was just then that I realized I did not know my API (as lean as it is) by heart and I had to go into the examples folder of my GIT repository to find it.

That is unacceptable, we need this stuff on the web, right?

Here we go then:

 7 require 'mockify'
 8 require 'verify'

10 Verify "Some Important Facts" do
11   verify "42 is true" do
12     42
13   end
14   refute "42 is pretty big" do
15     42 > 100_000
16   end
17   verify_exceptions NoMethodError do
18     42.unrelinguished!

20 end

22 Verify "With parameters" do
23   verify msg: "Everything is well", target: 42, actual: 21 * 2
24   refute msg: "But not too much",   target: 42, actual: 41

27 Verify "Capturing stdout" do
28   out = with_output do | o |
29     puts 42
30     verify target: "42\n", actual: o.string
31     puts
32     verify target: "42\n\n", actual: o.string
33   end
34   verify msg: "with_output converted out to an array of lines",
35     actual: out.map( &:chomp ),
36     target: [ "42", "" ]
37 end

39 Verify "Providing stdin" do
40   with_input %w{The Quick Brown Fox} do
41     verify %{first line is "The"} do
42       "The" == gets.chomp
43     end
44   end
45 end
