Provides a DSL for declaring a continuous integration workflow that can be run either locally or in the cloud. Each step is timed, reports success/error, and is aggregated into a collective report that reports total runtime, as well as whether the entire run was successful or not.

Example:

ActiveSupport::ContinuousIntegration.run do
  step "Setup", "bin/setup --skip-server"
  step "Style: Ruby", "bin/rubocop"
  step "Security: Gem audit", "bin/bundler-audit"
  step "Tests: Rails", "bin/rails test test:system"

  if success?
    step "Signoff: Ready for merge and deploy", "gh signoff"
  else
    failure "Skipping signoff; CI failed.", "Fix the issues and try again."
  end
end

Starting with Rails 8.1, a default ‘bin/ci` and `config/ci.rb` file are created to provide out-of-the-box CI.

run(title = "Continuous Integration", subtitle = "Running tests, style checks, and security audits", &block)

Perform a CI run. Execute each step, show their results and runtime, and exit with a non-zero status if there are any failures.

Pass an optional title, subtitle, and a block that declares the steps to be executed.

Sets the CI environment variable to “true” to allow for conditional behavior in the app, like enabling eager loading and disabling logging.

Example:

ActiveSupport::ContinuousIntegration.run do
  step "Setup", "bin/setup --skip-server"
  step "Style: Ruby", "bin/rubocop"
  step "Security: Gem audit", "bin/bundler-audit"
  step "Tests: Rails", "bin/rails test test:system"

  if success?
    step "Signoff: Ready for merge and deploy", "gh signoff"
  else
    failure "Skipping signoff; CI failed.", "Fix the issues and try again."
  end
end

echo(text, type:)

Echo text to the terminal in the color corresponding to the type of the text.

Examples:

echo "This is going to be green!", type: :success
echo "This is going to be red!", type: :error

See ActiveSupport::ContinuousIntegration::COLORS for a complete list of options.

# File activesupport/lib/active_support/continuous_integration.rb, line 111
def echo(text, type:)
  puts colorize(text, type)
end

failure(title, subtitle = nil)

Display an error heading with the title and optional subtitle to reflect that the run failed.

Source: show | on GitHub 

# File activesupport/lib/active_support/continuous_integration.rb, line 86
def failure(title, subtitle = nil)
  heading title, subtitle, type: :error
end

heading(heading, subtitle = nil, type: :banner, padding: true)

Display a colorized heading followed by an optional subtitle.

Examples:

heading "Smoke Testing", "End-to-end tests verifying key functionality", padding: false
heading "Skipping video encoding tests", "Install FFmpeg to run these tests", type: :error

See ActiveSupport::ContinuousIntegration::COLORS for a complete list of options.

def heading(heading, subtitle = nil, type: :banner, padding: true)
  echo "#{padding ? "\n\n" : ""}#{heading}", type: type
  echo "#{subtitle}#{padding ? "\n" : ""}", type: :subtitle if subtitle
end

step(title, *command)

Declare a step with a title and a command. The command can either be given as a single string or as multiple strings that will be passed to ‘system` as individual arguments (and therefore correctly escaped for paths etc).

Examples:

step "Setup", "bin/setup"
step "Single test", "bin/rails", "test", "--name", "test_that_is_one"

Source: show | on GitHub 

# File activesupport/lib/active_support/continuous_integration.rb, line 75
def step(title, *command)
  heading title, command.join(" "), type: :title
  report(title) { results << system(*command) }
end

success?()

Returns true if all steps were successful.

# File activesupport/lib/active_support/continuous_integration.rb, line 81
def success?
  results.all?
