read command line configuration options from files

RSpec reads command line configuration options from files in two different
locations:

Local: ./.rspec-local (i.e. in the project's root directory, can be gitignored)
Project: ./.rspec (i.e. in the project's root directory, usually checked into the project)
Global: ~/.rspec (i.e. in the user's home directory)

Configuration options are loaded from ~/.rspec, .rspec,
.rspec-local, command line switches, and the SPEC_OPTS environment
variable (listed in lowest to highest precedence; for example, an option
in ~/.rspec can be overridden by an option in .rspec-local).

Scenarios

color set in .rspec
custom options file
RSpec ignores ./.rspec when custom options file is used
using ERB in .rspec

color set in .rspec

Given

a file named ".rspec" with:

--color

And

a file named "spec/example_spec.rb" with:

describe "color" do
  context "when set with RSpec.configure" do
    before do
      # color is disabled for non-tty output, so stub the output stream
      # to say it is tty, even though we're running this with cucumber
      RSpec.configuration.output_stream.stub(:tty?) { true }
    end

    it "is true" do
      RSpec.configuration.should be_color_enabled
    end
  end
end

When

I run rspec ./spec/example_spec.rb

Then

the examples should all pass

custom options file

Given

a file named "my.options" with:

--format documentation

And

a file named "spec/example_spec.rb" with:

describe "formatter set in custom options file" do
  it "sets formatter" do
    RSpec.configuration.formatters.first.
      should be_a(RSpec::Core::Formatters::DocumentationFormatter)
  end
end

When

I run rspec spec/example_spec.rb --options my.options

Then

the examples should all pass

RSpec ignores ./.rspec when custom options file is used

Given

a file named "my.options" with:

--format documentation

And

a file named ".rspec" with:

--color

And

a file named "spec/example_spec.rb" with:

describe "custom options file" do
  it "causes .rspec to be ignored" do
    RSpec.configuration.color.should be_falsey
  end
end

When

I run rspec spec/example_spec.rb --options my.options

Then

the examples should all pass

using ERB in .rspec

Given

a file named ".rspec" with:

--format <%= true ? 'documentation' : 'progress' %>

And

a file named "spec/example_spec.rb" with:

describe "formatter" do
  it "is set to documentation" do
    RSpec.configuration.formatters.first.should be_an(RSpec::Core::Formatters::DocumentationFormatter)
  end
end

When

I run rspec ./spec/example_spec.rb

Then

the examples should all pass
