Installation
Add this line to your application's Gemfile:
gem 'rspec-stubbed_env', group: :test
And then execute:
$ bundle
Or install it yourself as:
$ gem install rspec-stubbed_env
You must configure RSpec to use the :expect
syntax, or some compatible alternative.
RSpec.configure do |config|
config.expect_with :rspec do |c|
c.syntax = :expect
end
end
Usage
ENV stubbing:
- is opt-in, via a shared context, rather than global.
- does not affect the real ENV at all. It is a true stub.
- has the same scope as a
before
,subject
, orlet
at the same level.
See the spec suite for detailed examples.
# This is normal, without stubbing, ENV is not set
describe 'vanilla' do
it 'has no ENV stub' do
expect(ENV['FOO']).to be_nil
end
end
# With a stubbed ENV!
describe 'my stubbed test' do
include_context 'with stubbed env'
before do
stub_env('FOO' => 'is bar')
end
it 'has a value' do
expect(ENV['FOO']).to eq('is bar')
end
end

Code of Conduct
Everyone interacting in the AnonymousActiveRecord project’s codebases, issue trackers, chat rooms and mailing lists is expected to follow the code of conduct.
Versioning
This library aims to adhere to Semantic Versioning 2.0.0. Violations of this scheme should be reported as bugs. Specifically, if a minor or patch version is released that breaks backward compatibility, a new version should be immediately released that restores compatibility. Breaking changes to the public API will only be introduced with new major versions.
As a result of this policy, you can (and should) specify a dependency on this gem using the Pessimistic Version Constraint with two digits of precision.
For example:
spec.add_dependency 'rspec-stubbed_env', '~> 1.0'
