README

        # RSpec::StubbedEnv

ENV stubbing via a shared context for more powerful tests.  Now you don't need to add dotenv just for your spec suite.

```ruby

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.fetch("FOO", nil)).to(eq("is bar"))

  end

end

```

## Installation

Add this line to your application's Gemfile:

```ruby

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.

```ruby

RSpec.configure do |config|

  config.expect_with(:rspec) do |c|

    c.syntax = :expect

  end

end

```

Require the library in your spec/test helper somewhere:

```

require "rspec/stubbed_env"

```

## 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`, or `let` at the same level.

See the spec suite for detailed examples.

```ruby

# This is normal, without stubbing, ENV is not set

describe "vanilla" do

  it "has no ENV stub" do

    expect(ENV.fetch("FOO", nil)).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.fetch("FOO", nil)).to(eq("is bar"))

  end

end

```

ENV can be stubbed trough the `stub_env` method, or key/value pairs to be stubbed can be provided directly to the `include_context` call:

```ruby

describe "my stubbed test" do

  include_context "with stubbed env", "FOO" => "is bar"

  it "has a value" do

    expect(ENV.fetch("FOO", nil)).to(eq("is bar"))

  end

end

```

If you want to make `stub_env` method available globally (without the `include_context` call), you can add in the `spec_helper`:

```ruby

RSpec.configure do |config|

  config.include(RSpec::StubbedEnv::TestHelpers)

end

```

## Switcch to `main` branch

We recently migrated from `master` to `main` as the default branch.  If this affected your local checkout:

```shell

git branch -m master main

git fetch origin

git branch -u origin/main main

git remote set-head origin -a

```

## Development

After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run `bundle exec rake install`.

## 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][conduct].

## Versioning

This library aims to adhere to [Semantic Versioning 2.0.0][semver].

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][pvc] with two digits of precision.

For example in a `Gemfile`:

    gem 'rspec-stubbed_env', '~> 1.0', group: [:development, :test]

or in a `gemspec`

    spec.add_development_dependency 'rspec-stubbed_env', '~> 1.0'
