rspec_sequel_matchers

Starting with version 0.4.0 this gem is only compatible with RSpec >= 3.x, if you want to use it with RSpec < 3.x use the 0.3.x versions.

Some Sequel Matchers for RSpec, using no other gem than rspec and sequel themself. As a consequence, you can use these matchers with Rails, Sinatra or any other framework. It's pretty feature complete.

Matchers assume that you're using the recommanded validation_helpers plugin. All instance validation methods are supported, namely:

validates_exact_length
validates_format
validates_includes
validates_integer
validates_length_range
validates_max_length
validates_min_length
validates_not_string
validates_numeric
validates_presence
validates_unique

Each one with all possible options, namely:

:allow_blank
:allow_missing
:allow_nil
:message

There're also matchers for associations class methods:

:many_to_many
:many_to_one
:one_to_many
:one_to_one
:many_through_many

And there's an additionnal matcher have_column to check columns existance and their type, see example usage bellow.

RspecSequel::Matchers has an extensive test suite and will give you as much explanation as possible in failure messages such as expected column type versus column type found in database.

Install

gem install rspec_sequel_matchers
