Feature: customized message
In order to get the feedback I want
As an RSpec user
I want to customize the failure message per example
Scenario: one additional method
Given a file named "node_spec.rb" with:
"""
class Node
def initialize(state=:waiting)
@state = state
end
def state
@state
end
def waiting?
@state == :waiting
end
def started?
@state == :started
end
def start
@state = :started
end
end
describe "a new Node" do
it "should be waiting" do
node = Node.new(:started) #start w/ started to trigger failure
node.should be_waiting, "node.state: #{node.state} (first example)"
end
it "should not be started" do
node = Node.new(:started) #start w/ started to trigger failure
node.should_not be_started, "node.state: #{node.state} (second example)"
end
end
describe "node.start" do
it "should change the state" do
node = Node.new(:started) #start w/ started to trigger failure
lambda {node.start}.should change{node.state}, "expected a change"
end
end
"""
When I run "rspec ./node_spec.rb --format documentation"
Then the output should contain "3 examples, 3 failures"
And the output should not contain "to return true, got false"
And the output should not contain "to return false, got true"
And the output should contain "node.state: started (first example)"
And the output should contain "node.state: started (second example)"
And the output should contain "expected a change"
