Test Driving a Rails API - Part Two

1. dotenv

   1 23 6,663 7.4 Ruby

   A Ruby gem to load environment variables from `.env`. (by bkeepers)

   

   This is the second part of my Test Driving a Rails API series. In Part 1 we set up our development environment, generated a Rails API-only application, installed dotenv to easily store configuration values in the environment, and installed and configured PostgreSQL version 16 as our database.

2. InfluxDB

   InfluxDB – Built for High-Performance Time Series Workloads. InfluxDB 3 OSS is now GA. Transform, enrich, and act on time series data directly in the database. Automate critical tasks and eliminate the need to move data externally. Download now.

   

3. minitest

   2 13 3,325 7.4 Ruby

   minitest provides a complete suite of testing facilities supporting TDD, BDD, mocking, and benchmarking.

   

   In this part, we’ll set up our testing environment so that we can test our Rails API using minitest with minitest/spec. We’ll look at the differences between traditional style unit tests and spec-style tests, or specs. I’ll demonstrate why you should use minitest-rails. We’ll look at using rack-test for testing our API. We’ll even create our own generator to generate API specs.

4. rspec-rails

   3 25 5,221 8.8 Ruby

   RSpec for Rails 7+

   

   When starting a Rails project, you have a lot of decisions to make. Whether or not to write tests should not be one of them. The big decision is to use Minitest or Rspec. Both of those testing frameworks are great and provide everything you need to test a Rails application thoroughly.

5. minitest-rails

   4 1 554 5.7 Ruby

   Minitest integration for Rails

   

   How do we tell minitest/spec which test class to use? The tldr is to use the minitest-rails gem. I highly recommend adding the minitest-rails gem to your project. The gem does a lot to integrate the Rails testing ecosystem with Minitest, particularly spec-style tests. One primary benefit is that it configures specs to use ActiveSupport::TestCase or one of its subclasses as the spec’s test class, depending on what is passed describe.

6. rack-test

   5 2 927 6.2 Ruby

   Rack::Test is a small, simple testing API for Rack apps.

   

   In this part, we’ll set up our testing environment so that we can test our Rails API using minitest with minitest/spec. We’ll look at the differences between traditional style unit tests and spec-style tests, or specs. I’ll demonstrate why you should use minitest-rails.

7. factory_bot_rails

   6 9 3,109 7.4 Ruby

   Factory Bot ♥ Rails

   

   While we’re at it, let's add a couple of other gems we’ll need for our test environment: factory_bot_rails is a fixtures replacement and generates test model instances. faker is handy for generating fake strings of data to be used in tests. Add those gems to the development and test group of your Gemfile:

8. faker

   7 45 11,355 8.3 Ruby

   A library for generating fake data such as names, addresses, and phone numbers. (by faker-ruby)
