So I guess this means that the before block for the shared example
group gets executed after the example group using it. I don't recall
seeing this documented, although I'm sure that it is.
This helps me a lot.
Can you do something similar with the new nested example groups? It
doesn't seem so.
describe "Shared", :shared => true do
before(:each) do
@outer = @inner
end
it "should set @outer to @inner" do
@outer.should == @inner
end
end
describe "Sharer" do
it_should_behave_like "Shared"
it "should set @outer to 1" do
@inner = 1
end
end
describe "Outer" do
before(:each) do
@outer = @inner
end
describe "inner one" do
before(:each) do
@inner = 1
end
it "should be set outer to 1" do
@outer.should == 1
end
end
describe "inner two" do
before(:each) do
@inner = 2
end
it "should be set outer to 1" do
@outer.should == 2
end
end
end
