Tset

Tset generates tests for your models in your Rails application.

TDD is great, but sometimes you just want to write some codes.

Enter 'Development Driven Test'. Tset enables you to just write codes and worry about tests later.

Run installation command.

gem install tset

OR if you want to use bundler,

gem 'tset', group: :development

Run bundle install.

Append bundle exec when you run tset commands.

In your application root directory, run the generator.

tset generate model YOUR_MODEL_NAME

Tset will read your model and generate a test accordingly.

If your model looks like the following,

class Post < ActiveRecord::Base
  validates_presence_of :author
  validates_length_of :author, maximum: 30
  belongs_to :author
end

Tset will generate a spec file such as:

require 'spec_helper'

describe Post do

  describe "associations" do
    it { is.expected_to belong_to(:author) }
  end

  describe "validations" do
    it { is.expected_to ensure_length_of(:author).is_at_most(30) }
    it { is.expected_to validate_presence_of(:author) }
  end
end

By default, the Tset will use RSpec. Help us add Minitest support by contributing.

You need shoulda-matchers to run some of tests Tset generates for you.

It lets you use matchers such as validate_presence_of(:name) in your spec.

There are four main objects at play: Analyzer, Translator, Writer, and Generator.

• Analyzer reads your model file, and matches any lines that are deemed 'testable'. It returns an array of Tset::Testable objects.

• Translator converts Tset::Testable objects into Tset::Test objects.

• Writer writes the actual test in the spec file, for each Tset::Test objects.

• Generator copies spec templates, groups all major components together, and responds to CLI.

Tset is a test spelled backwards.

Tset is in beta. We need your help to improve it.

• Add more translation rules for testables (located in tset/translators/rspec.rb).
• Support Minitest.
• Support controllers.
