You are correct

Maybe I didn't well understand the object of your post!

The test is (as you can see in function dotest):

Expect(ans).To(Equal(exp))

which is quite general and "github.com/onsi/ginkgo" + "github.com/onsi/gomega"

Expected
    <[]string | len:0, cap:0>: nil
to equal
    <[]string | len:0, cap:0>: []
