More about adding a collaboratorcustomized message
RSpec tries to provide useful failure messages, but for cases in which you want more
specific information, you can define your own message right in the example.This works for
any matcher other than the operator matchers.

RSpec.describe Array do context "when created with
new
" do it "is empty" do array = Array.new array << 1 # trigger a failure to demonstrate the message expect(array).to be_empty, "expected empty array, got #{array.inspect}" end end end - When
-
I run
rspec example_spec.rb --format documentation
- Then
- the output should contain "expected empty array, got [1]"
