before_cmd hooks

You can configure Aruba to run blocks of code before it runs
each command.

The command will be passed to the block.

You can hook into Aruba's lifecycle just before it runs a command and after it has run the command:

require_relative 'aruba'

Aruba.configure do |config|
  config.before :command do |cmd|
    puts "About to run '#{cmd}'"
  end
end

Background

Given: I use a fixture named "cli-app"

Scenarios

Run a simple command with a "before(:command)"-hook

Given

a file named "spec/support/hooks.rb" with:

require_relative 'aruba'

Aruba.configure do |config|
  config.before :command do |cmd|
    puts "before the run of #{cmd.commandline}"
  end
end

And

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

require 'spec_helper'

RSpec.describe 'Hooks', :type => :aruba do
  before(:each) { run_simple 'echo running' }

  it { expect(last_command_started.stdout.chomp).to eq 'running' }
end

When

I run rspec

Then

the specs should all pass

And

the output should contain:

before the run of echo running

Run a simple command with a "before(:cmd)"-hook (deprecated)

Given

a file named "spec/support/hooks.rb" with:

require_relative 'aruba'

Aruba.configure do |config|
  config.before :cmd do |cmd|
    puts "before the run of #{cmd}"
  end
end

And

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

require 'spec_helper'

RSpec.describe 'Hooks', :type => :aruba do
  before(:each) { run_simple 'echo running' }

  it { expect(last_command_started.stdout.chomp).to eq 'running' }
end

When

I run rspec

Then

the specs should all pass

And

the output should contain:
