Matchi is cryptographically signed.
To be sure the gem you install hasn't been tampered with, add my public key (if you haven't already) as a trusted certificate:
$ gem cert --add <(curl -Ls https://raw.github.com/fixrb/matchi/master/certs/gem-fixrb-public_cert.pem)
$ gem install matchi -P HighSecurity
The HighSecurity
trust profile will verify all gems. All of Matchi's
dependencies are signed.
Or add this line to your application's Gemfile:
gem 'matchi'
And then execute:
$ bundle
Equivalence matcher:
eql = Matchi::Matchers::Eql::Matcher.new('foo')
eql.matches? { 'foo' } # => true
Identity matcher:
equal = Matchi::Matchers::Equal::Matcher.new(:foo)
equal.matches? { :foo } # => true
Regular expressions matcher:
match = Matchi::Matchers::Match::Matcher.new(/^foo$/)
match.matches? { 'foo' } # => true
Expecting errors matcher:
raise_exception = Matchi::Matchers::RaiseException::Matcher.new(NameError)
raise_exception.matches? { Boom } # => true
Truth matcher:
be_true = Matchi::Matchers::BeTrue::Matcher.new
be_true.matches? { true } # => true
Untruth matcher:
be_false = Matchi::Matchers::BeFalse::Matcher.new
be_false.matches? { false } # => true
Nil matcher:
be_nil = Matchi::Matchers::BeNil::Matcher.new
be_nil.matches? { nil } # => true
Custom matchers can easily be defined for expressing expectations. They can be any Ruby class that responds to matches?
, to_s
and to_h
instance methods.
A Be the answer matcher:
module Matchi
module Matchers
module BeTheAnswer
class Matcher
def matches?
42.equal? yield
end
def to_s
'be_the_answer'
end
def to_h
{ BeTheAnswer: [] }
end
end
end
end
end
be_the_answer = Matchi::Matchers::BeTheAnswer::Matcher.new
be_the_answer.matches? { 42 } # => true
A Be prime matcher:
require 'prime'
module Matchi
module Matchers
module BePrime
class Matcher
def matches?
Prime.prime? yield
end
def to_s
'be_prime'
end
def to_h
{ BePrime: [] }
end
end
end
end
end
be_prime = Matchi::Matchers::BePrime::Matcher.new
be_prime.matches? { 42 } # => false
A Start with matcher:
module Matchi
module Matchers
module StartWith
class Matcher
def initialize(expected)
@expected = expected
end
def matches?
!Regexp.new("^#{@expected}").match(yield).nil?
end
def to_s
'start_with'
end
def to_h
{ StartWith: [@expected] }
end
end
end
end
end
start_with = Matchi::Matchers::StartWith::Matcher.new('foo')
start_with.matches? { 'foobar' } # => true
As a basic form of security Matchi provides a set of SHA512 checksums for
every Gem release. These checksums can be found in the checksum/
directory.
Although these checksums do not prevent malicious users from tampering with a
built Gem they can be used for basic integrity verification purposes.
The checksum of a file can be checked using the sha512sum
command. For
example:
$ sha512sum pkg/matchi-0.0.1.gem
548d9f669ded4e622182791a5390aaceae0bf2e557b0864f05a842b0be2c65e10e1fb8499f49a3b9efd0e8eaeb691351b1c670d6316ce49965a99683b1071389 pkg/matchi-0.0.1.gem
