1st things 1st

thanks @jimweirich for rspec-given!

a brief history

In the beginning was xUnit public void somethingSomething() { SandwichMaker subject = new SandwichMaker(); Sandwich sandwich = subject.make(); assertEquals(sandwich.getBread(),SOME_BREAD); }

In the beginning was xUnit public void somethingSomething() { SandwichMaker subject = new SandwichMaker(); Sandwich sandwich = subject.make(); assertEquals(sandwich.getBread(),SOME_BREAD); } Arrange

In the beginning was xUnit public void somethingSomething() { SandwichMaker subject = new SandwichMaker(); Sandwich sandwich = subject.make(); assertEquals(sandwich.getBread(),SOME_BREAD); } Arrange Act

In the beginning was xUnit public void somethingSomething() { SandwichMaker subject = new SandwichMaker(); Sandwich sandwich = subject.make(); assertEquals(sandwich.getBread(),SOME_BREAD); } Arrange Act Assert

and so began our wonderful addiction to GREEN BARS

then along came should public void itShouldHaveBread() { SandwichMaker subject = new SandwichMaker(); Sandwich sandwich = subject.make(); assertThat(sandwich).hasBread(); }

then along came should public void itShouldHaveBread() { SandwichMaker subject = new SandwichMaker(); Sandwich sandwich = subject.make(); assertThat(sandwich).hasBread(); } public void itShouldHaveCheese() { SandwichMaker subject = new SandwichMaker(); Sandwich sandwich = subject.make(); assertThat(sandwich).hasCheese(); }

RSpec gave us DRY specs that retained readability describe MakesSandwiches describe “#make” it “has bread” do subject = MakesSandwiches.new sandwich = subject.make() sandwich.should have_bread end end end

and rspec-given made an honest DSL of it. describe MakesSandwiches Given(:subject) { MakesSandwiches.new } describe “#make” When(:sandwich) { subject.make() } Then { sandwich.should have_bread } Then { sandwich.should have_cheese } end end

so then I just ported that same thing to jasmine. describe "MakesSandwiches", -> Given -> @subject = new MakesSandwiches describe "#make", -> When -> @sandwich = @subject.make() Then -> expect(@sandwich).toHave("bread") Then -> expect(@sandwich).toHave("cheese")

so then I just ported that same thing to jasmine. describe "MakesSandwiches", -> Given -> @subject = new MakesSandwiches describe "#make", -> When -> @sandwich = @subject.make() Then -> expect(@sandwich).toHave("bread") Then -> expect(@sandwich).toHave("cheese") go run it on tryjasmine.com! http://is.gd/givensandwich
