To add a collaborator to this project you will need to use the Relish gem to add the collaborator via a terminal command. Soon you'll be able to also add collaborators here!
More about adding a collaboratorexist matcher
The exist matcher is used to specify that something exists
(as indicated by #exist?):
obj.should exist # passes if obj.exist?
- Scenarios
-
- basic usage
-
- Given
-
a file named "exist_matcher_spec.rb" with:
class Planet attr_reader :name def initialize(name) @name = name end def inspect "<Planet: #{name}>" end def exist? %w[Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune].include?(name) end end describe "Earth" do subject { Planet.new("Earth") } it { should exist } it { should_not exist } # deliberate failure end describe "Tatooine" do subject { Planet.new("Tatooine") } it { should_not exist } it { should exist } # deliberate failure end
- When
- I run "rspec exist_matcher_spec.rb"
- Then
-
the output should contain all of these:
4 examples, 2 failures expected <Planet: Earth> not to exist expected <Planet: Tatooine> to exist
