SequelSpec

SequelSpec is a refactor of rspec_sequel_matchers borrowing concepts from shoulda-matchers. In contrast with rspec_sequel_matchers it provides a sweeter syntax and it doesn't rely on a specific mocking framework.

Installation

Add this line to your application's Gemfile:

gem 'sequel_spec', :group => :test

And then execute:

$ bundle

Or install it yourself as:

$ gem install sequel_spec

Usage

The matchers are automatically included on RSpec. Just use them at will.

Association

it { should have_many_to_many :items }
it { should have_many_to_one :item }
it { should have_one_to_many :comments }
it { should have_one_to_one :photo }
it { should have_one_through_one :author }

You can specify options using #with_options

it { should have_one_through_one(:author).with_options :key => :user_id }

Validation

# Format
it { should validate_format_of(:name).with(/\w+/) }

# Inclusion
it { should ensure_inclusion_of(:name).in(['John', 'Smith']) }

# Integrity (valid integer)
it { should validate_integrity_of(:age) }

# Length
it { should validate_length_of(:name).is(20) }
it { should validate_length_of(:name).is_at_least(20) }
it { should validate_length_of(:name).is_at_most(20) }
it { should validate_length_of(:name).is_between(2..20) }

# Not null
it { should validate_not_null(:category_id) }

# Numericality (valid float)
it { should validate_numericality_of(:price) }

# Type
it { should validate_type_of(:birthdate).is Date }

# Uniqueness
it { should validate_uniqueness_of(:username) }

This matchers accepts options through #with_options as well

it { should validate_uniqueness_of(:username).with_options :message => "This username is already taken" }

Or with the specialized helpers: #allowing_nil, #allowing_blank, #allowing_missing, and #with_message

it { should validate_length_of(:name).is(20).allowing_nil }
it { should validate_length_of(:name).is(20).allowing_blank }
it { should validate_length_of(:name).is(20).allowing_missing }
it { should validate_length_of(:name).is(20).with_message "Name should be 20 chars long" }
