Simple validation test generator for rails.

Tamebou generates a simple test for validation of rails.

It read single-line validates methods and write test code according to templates. the default fomart is prepared for minitest and rspec.

cover validation options

exclusion
inclusion
length
numericality
presence

For other validation options, Tamebou generates a template with placeholders.

Installation

$ gem install tamebou

Usage

class Sample < ActiveRecord::Base
  validates :name, length: { maximum: 32, minimum: 6 }, presence: true
  validates :id, numericality: { only_integer: true, greater_than: 0 }

  # ...
end

if you want to use template for RSpec:

Tamebou::Writer.new("../path/to/model/sample.rb", Tamebou::Writer::DefaultTemplate::RSPEC).write

if you want to use custom template:

Tamebou::Writer.new("../path/to/model/sample.rb", "/path/to/your_template").write
