EnvTestHelpers

EnvTestHelpers is a collection of helpers to work with environment variables in tests. Right now is only working with Rspec.

Use case:

• I have configurations set in ignored files, most of this variables are Api keys or passwords.
• The code and tests needs this variables but I can not share them in my VCS.

Solution:

• I mock or set this variables in the test they are required.

Installation

Add this line to your application's Gemfile:

gem 'env_test_helpers', group: :test

And then execute:

$ bundle

Or install it yourself as:

$ gem install env_test_helpers

RSpec

All done. The module gets included in the rspec configure block.

Else

Right now only works with RSpec.

Usage

Using the variables inside a block:

it 'does something with the FOO environment variable' do
  with_env_vars 'FOO' => 'bar' do
    # logic that depends upon ENV['FOO'] goes here
  end
end

As a before block:

describe Thing do
  before(:all) do
    mock_env_vars('FOO' => 'bar')
  end
  it 'does something with the FOO environment variable' do
    # logic that depends upon ENV['FOO'] goes here
  end
end
