RSpec Integration

When using Rspec, the way it turns question mark methods into be_ methods is a perfect fit for our match? method.

RSpec converts match? to be_match

# The following two lines are equivalent
expect(Kt.compare('abc', 'abc').match?).to be true
expect(Kt.compare('abc', 'abc')).to be_match

For when you don't want a match, RSpec has a helpful utility for defining the opposite of a matcher.

RSpec defines negated matchers

RSpec::Matchers.define_negated_matcher :be_mismatch, :be_match
expect(Kt.compare('abc', 123)).to be_mismatch

We've also added RSpec matchers to make testing your shapes even easier.

RSpec custom matchers

require 'katachi/rspec'

expect(Kt.compare('abc', 123)).to have_compare_code(:mismatch)
expect('abc').to have_shape(String)
expect('abc').to have_shape('abc').with_code(:exact_match)
