Matchi::Rspec

Extend Matchi matchers with some RSpec's ones.

Add this line to your application's Gemfile:

gem "matchi-rspec"

And then execute:

bundle

Or install it yourself as:

gem install matchi-rspec

To make Matchi::Rspec available:

require "matchi/rspec"

All examples here assume that this has been done.

Identity matcher:

be = Matchi::Matcher::Be.new(42)
be.matches? { 42 } # => true

Type/class matcher:

be_instance_of = Matchi::Matcher::BeInstanceOf.new(String)
be_instance_of.matches? { "foo" } # => true

Equivalence matcher:

eq = Matchi::Matcher::Eq.new("foo")
eq.matches? { "foo" } # => true

For convenience, it is possible to instantiate a matcher with a method rather than with its class. To do so, the Helper module can be included like this:

require "matchi/helper"

class MatcherCollection
  include ::Matchi::Helper
end

The set of loaded matcher then becomes accessible via a dynamically generated instance method, like these:

matcher = MatcherCollection.new
matcher.be(42).matches? { 44 } # => false
matcher.be_instance_of(String).matches? { "안녕하세요" } # => true
