Feature: Change current working directory
If you need to run some code in a different directory you can use the `cd`
command. It comes in two flavors:
\* First can simply use `cd 'some-dir'`
\* Second can use the block notation `cd('some-dir') { Dir.getwd }`
If you chose to use the latter one, the result of your block is returned. The
current working directory is only changed for the code inside the block -
it's use is side effect free.
Background:
Given I use a fixture named "cli-app"
Scenario: Existing directory
Given a file named "spec/cd_spec.rb" with:
"""ruby
require 'spec_helper'
RSpec.describe 'cd to directory', :type => :aruba do
before(:each) do
create_directory 'new_dir.d'
cd 'new_dir.d'
end
before(:each) { run_command_and_stop 'pwd' }
it { expect(last_command_started.output).to include 'new_dir.d' }
end
"""
When I run `rspec`
Then the specs should all pass
Scenario: Non-Existing directory
Given a file named "spec/cd_spec.rb" with:
"""ruby
require 'spec_helper'
RSpec.describe 'cd to directory', :type => :aruba do
before(:each) { cd 'new_dir.d' }
before(:each) { run_command_and_stop 'pwd' }
it { expect(last_command_started.output).to include 'new_dir.d' }
it { expect(last_command_started).to be_executed_in_time }
end
"""
When I run `rspec`
Then the specs should not pass
Scenario: With block in it-block
Given a file named "spec/cd_spec.rb" with:
"""ruby
require 'spec_helper'
RSpec.describe 'cd to directory', :type => :aruba do
before(:each) do
create_directory 'new_dir.d/subdir.d'
end
it do
cd('new_dir.d/subdir.d') { expect(Dir.getwd).to include 'new_dir.d/subdir.d' }
end
end
"""
When I run `rspec`
Then the specs should all pass
Scenario: With block in before-block
Running `cd` with a block does not change:
\* The current directory - `Dir.getwd`
\* Aruba's current directory
Given a file named "spec/cd_spec.rb" with:
"""ruby
require 'spec_helper'
RSpec.describe 'cd to directory', :type => :aruba do
before(:each) do
create_directory 'new_dir.d/subdir.d'
end
before :each do
cd('new_dir.d/subdir.d') do
# you code
end
end
it { expect(Dir.getwd).not_to include 'new_dir.d/subdir.d' }
it { expect(expand_path('.')).not_to include 'new_dir.d/subdir.d' }
end
"""
When I run `rspec`
Then the specs should all pass
Scenario: The result of the block is returned
If you need to run some code in a different directory, you can also use the
block-notation of `cd`.

"""ruby
require 'spec_helper'
RSpec.describe 'cd to directory', :type => :aruba do

end
it { expect(@my_output).to include 'new_dir.d/subdir.d' }
end
"""
When I run `rspec`
Then the specs should all pass
Scenario: It changes the PWD- and OLDPWD-ENV-variable for a given block
If you need to run some code in a different directory, you can also use the
block-notation of `cd`.
Given a file named "spec/cd_spec.rb" with:
"""ruby

it { expect(@oldpwd).to end_with 'cli-app' }
end
"""
When I run `rspec`
Then the specs should all pass
Scenario: Nested cd calls
If you need to run some code in a different directory, you can also use the
block-notation of `cd`.
Given a file named "spec/cd_spec.rb" with:
