Delete existing environment variable via API-method

It is quite handy to modify the environment of a process. To make this
possible, aruba provides several methods. One of these is
#delete_environment_variable. Using this remove an existing variable.

Background

Given: I use the fixture "cli-app"

Scenarios

Non-existing variable
Existing variable set from within the test
Existing variable set by some outer parent process

Non-existing variable

Given

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

require 'spec_helper'

RSpec.describe 'Long running command', :type => :aruba do
  before(:each) { delete_environment_variable 'LONG_LONG_VARIABLE' }

  before(:each) { run('env') }
  before(:each) { stop_all_commands }

  it { expect(last_command_started.output).not_to include 'LONG_LONG_VARIABLE=1' }
end

When

I run rspec

Then

the specs should all pass

Existing variable set from within the test

Given

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

require 'spec_helper'

RSpec.describe 'Long running command', :type => :aruba do
  before(:each) { set_environment_variable 'LONG_LONG_VARIABLE', '1' }
  before(:each) { delete_environment_variable 'LONG_LONG_VARIABLE' }

  before(:each) { run('env') }
  before(:each) { stop_all_commands }

  it { expect(last_command_started.output).not_to include 'LONG_LONG_VARIABLE' }
end

When

I run rspec

Then

the specs should all pass

Existing variable set by some outer parent process

Given

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

require 'spec_helper'

ENV['REALLY_LONG_LONG_VARIABLE'] = '1'

RSpec.describe 'Environment command', :type => :aruba do
  before(:each) { delete_environment_variable 'REALLY_LONG_LONG_VARIABLE' }

  before(:each) { run('env') }
  before(:each) { stop_all_commands }

  it { expect(last_command_started.output).not_to include 'REALLY_LONG_LONG_VARIABLE' }
end

When
