Define default process environment

Say you want to have a default set of environment variables, then use this
code.

Aruba.configure do |config|
  config.command_runtime_environment = { 'MY_VARIABLE' => 'x' }
end

This can be changed via #set_environment_variable,
#append_environment_variable, #delete_environment_variable or
#prepend_environment_variable.

Background

Given: I use the fixture "cli-app"

Scenarios

Overwrite existing variable with new default value
Overwrite default value for variable
Append value to default value
Prepend value
Remove variable from default set of variables

Overwrite existing variable with new default value

Given

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

require 'spec_helper'

ENV['LONG_LONG_VARIABLE'] = 'y'

Aruba.configure do |config|
  config.command_runtime_environment = { 'LONG_LONG_VARIABLE' => 'x' } 
end

RSpec.describe 'Environment command', :type => :aruba do
  before(:each) { run('env') }
  before(:each) { stop_all_commands }

  it { expect(last_command_started.output).to include 'LONG_LONG_VARIABLE=x' }
end

When

I run rspec

Then

the specs should all pass

Overwrite default value for variable

Given

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

require 'spec_helper'

ENV['LONG_LONG_VARIABLE'] = 'y'

Aruba.configure do |config|
  config.command_runtime_environment = { 'LONG_LONG_VARIABLE' => 'x' } 
end

RSpec.describe 'Environment command', :type => :aruba do
  before(:each) { set_environment_variable 'LONG_LONG_VARIABLE', 'z' }

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

  it { expect(last_command_started.output).to include 'LONG_LONG_VARIABLE=z' }
end

When

I run rspec

Then

the specs should all pass

Append value to default value

Given

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

require 'spec_helper'

ENV['LONG_LONG_VARIABLE'] = 'y'

Aruba.configure do |config|
  config.command_runtime_environment = { 'LONG_LONG_VARIABLE' => 'x' } 
end

  before(:each) { append_environment_variable 'LONG_LONG_VARIABLE', 'z' }

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

  it { expect(last_command_started.output).to include 'LONG_LONG_VARIABLE=xz' }
end

When

I run rspec

Then

the specs should all pass

Prepend value

Given

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

require 'spec_helper'

ENV['LONG_LONG_VARIABLE'] = 'y'

Aruba.configure do |config|
  config.command_runtime_environment = { 'LONG_LONG_VARIABLE' => 'x' } 
end

RSpec.describe 'Environment command', :type => :aruba do
  before(:each) { prepend_environment_variable 'LONG_LONG_VARIABLE', 'z' }

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

  it { expect(last_command_started.output).to include 'LONG_LONG_VARIABLE=zx' }

Remove variable from default set of variables

Given

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

require 'spec_helper'

ENV['LONG_LONG_VARIABLE'] = 'y'

Aruba.configure do |config|
  config.command_runtime_environment = { 'LONG_LONG_VARIABLE' => 'x' } 
end

RSpec.describe 'Environment 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' }
end

When

I run rspec

Then

the specs should all pass
