@ruby-1.9
Feature: cover matcher
Use the cover matcher to specify that a range covers one or more
expected objects. This works on any object that responds to #cover? (such
as a Range):
```ruby
(1..10).should cover(5)
(1..10).should cover(4, 6)
(1..10).should_not cover(11)
```
Scenario: range usage
Given a file named "range_cover_matcher_spec.rb" with:
"""ruby
describe (1..10) do
it { should cover(4) }
it { should cover(6) }
it { should cover(8) }
it { should cover(4, 6) }
it { should cover(4, 6, 8) }
it { should_not cover(11) }
it { should_not cover(11, 12) }
# deliberate failures
it { should cover(11) }
it { should_not cover(4) }
it { should_not cover(6) }
it { should_not cover(8) }
it { should_not cover(4, 6, 8) }
# both of these should fail since it covers 5 but not 11
it { should cover(5, 11) }
it { should_not cover(5, 11) }
end
"""
When I run `rspec range_cover_matcher_spec.rb`
Then the output should contain all of these:
| 14 examples, 7 failures |
| expected 1..10 to cover 11 |
| expected 1..10 not to cover 4 |
| expected 1..10 not to cover 6 |
| expected 1..10 not to cover 8 |
| expected 1..10 not to cover 4, 6, and 8 |
| expected 1..10 to cover 5 and 11 |
| expected 1..10 not to cover 5 and 11 |
|
