1. Describe block
describe "describes" do
before(:each) do
this will execute every time
end
it “it describes” do
should
should_not
end
end
2. Should and should_not method
receiver.should(matcher) # the simplest example
# Passes if matcher.matches?(receiver)
receiver.should == expected #any value
# Passes if (receiver == expected)
receiver.should === expected #any value
# Passes if (receiver === expected)
receiver.should =~ regexp
# Passes if (receiver =~ regexp)
alse can use
target.should be_true
target.should be_false
target.should be_nil
target.should_not be_nil
3.should be_a_kind_of(Fixnum)
3.should be_an_instance_of(Fixnum)
{:foo => “foo”}.should have_key(:foo)
[1, 2, 3].should include(1)
[1, 2, 3].should have(3).items
3. Shared Behaviors
• before(:all)
• before(:each)
• after(:each)
• after(:all)
describe “people in general”
before(:each) do
puts “shared before()”
end
after(:each) do
puts “shared after()”
end
...
end
describe Teacher do
before(:each) do
puts “teacher before()”
@person = Teacher.new(“Ms. Smith”, 30, 50000)
end
after(:each) do
puts “teacher after()”
end
it_should_behave_like “people in general”
...
end
it_should_behave_like “people in general” can shared methods in people in general. Cool! 4. RSpec’s Mocks and Stubs
Mock Objects
echo.should_receive(:sound).with(“hey”).and_return(“hey”)
Stub Objects
yodeler = stub(‘yodeler’, :yodels? => true)
5. Running Specs
$ spec spec/models/credit_card_spec.rb
$ spec -fs spec/models/credit_card_spec.rb
$ spec -fr spec/models/authorization_spec.rb
6. The RSpec on Rails Plugin
$ script/generate rspec
$ script/generate rspec_model Schedule name:string
