Hello everyone,
I added a new instance method in Sequel::Plugins::ValidationHelpers and I
am trying to have specs for it. I checked out it is done for the other
methods in the specs of the Sequel project. Here's my code:
module Sequel::Plugins::ValidationHelpers
module InstanceMethods
# PARAMS (Integer, Symbol)
def validates_greater_than(value, column)
column = send(column)
if column.is_a? Integer
if column <= value
errors.add(column, "must be greater than #{value}")
end
else
errors.add(column, "must be of type Integer to be validated"
)
end
end
end
end
Then my specs:
spec_helper.rb
ENV["RACK_ENV"] = "test"
require "bundler"
Bundler.require :default, :test
require "rack/test"
require "minitest/autorun"
# TODO Check if the app lines are needed only for routes spec... then
transfer them or not
# Load the Sinatra application
require_relative "../app.rb"
include Rack::Test::Methods
def app
BDV_App
end
sequel_plugins_validationhelpers_spec.rb
require_relative "../spec_helper"
describe "Sequel::Plugins::ValidationHelpers" do
before do
@c = Class.new(Sequel::Model) do
def self.set_validations(&block)
define_method(:validate, &block)
end
columns :value
end
@c.plugin :validation_helpers
@m = @c.new
end
describe "#validates_greater_than" do
describe "a column which is of type Integer" do
describe "having a value smaller than the value received" do
end
describe "having a value equal to the value received" do
end
describe "having a value greater than the value received" do
end
end
describe "a column which isn't of type Integer" do
it "must not be valid" do
end
end
end
end
My problem is that I keep getting an error when running my tests. This is
the error I get:
Sequel::Plugins::ValidationHelpers::#validates_greater_than::a column which
isn't of type Integer#test_0001_must not be valid:
ArgumentError: wrong number of arguments (1 for 0)

`block (2 levels) in <top (required)>'
What would be the best way to test my new instance method? Am I doing too
much by trying to replicate the specs in the Sequel project?
