Use the `chain` method to define matchers with a fluent interface.
Scenario: chained method with argument
Given a file named "between_spec.rb" with:
"""ruby
RSpec::Matchers.define :be_bigger_than do |first|
match do |actual|
(actual > first) && (actual < @second)
end
chain :and_smaller_than do |second|
@second = second
end
end
RSpec.describe 5 do
it { is_expected.to be_bigger_than(4).and_smaller_than(6) }
end
"""
When I run `rspec between_spec.rb --format documentation`
Then the output should contain "1 example, 0 failures"
And the output should contain "should be bigger than 4"
Scenario: chained setter
Given a file named "between_spec.rb" with:
"""ruby
RSpec::Matchers.define :be_bigger_than do |first|
match do |actual|
(actual > first) && (actual < second)
end

end
RSpec.describe 5 do
it { is_expected.to be_bigger_than(4).and_smaller_than(6) }
end
"""
