RSpec-esque matchers for Test::Unit
= matchy
== DESCRIPTION: Hate writing assertions? Need a little behavior-driven love in your tests? Then matchy is for you.
== FEATURES/PROBLEMS:
== SYNOPSIS:
Get BDD on your objects
x = 13 * 4 x.should == 42
y = "hello" y.length.should_not be(4)
Use familiar syntax to specify things
"my string".should =~ /string/ lambda { raise "FAIL" }.should raise_error
"my string".should =~ /string/ lambda { raise "FAIL" }.should raise_error
Most of familiar RSpec Matchers are built in
lambda {raise}.should raiseerror #pass lambda {raise MyCustomError.new}.should raiseerror(MyCustomError) #pass lambda {raise "message"}.should raiseerror("message") #pass lambda {raise "message"}.should raiseerror(/essa/) #pass
lambda {@var+=1}.should change {@var}
lambda { }.should change {@var}
@var = 1 lambda {@var+=1}.should change {@var}.from(1).to(2)
@obj.should be_something
Get the speed of Test:Unit with the syntax of RSpec
Create your own matchers
defmatcher :benil do |receiver, matcher, args| receiver.nil? end
nil.should benil # pass nil.shouldnot benil # fails 'notnil'.should benil # fails 'notnil'.shouldnot benil # pass
defmatcher :have do |receiver, matcher, args|
count = args[0]
something = matcher.msgs[0].name
actual = receiver.send(something).length
matcher.positivemsg = "Expected #{receiver} to have #{actual} #{something}, but found #{count} "
actual == count
end
class Thing def widgets @widgets ||= [] end end @thing.should have(3).widgets
