Defined in:
lib/origen/regression_manager.rb

Overview

Supports executing code regression testing.

Reference workspace used for comparison will automatically be populated based on tag selected (default: latest).

An instance of this class is hooked up to:

Origen.regression_manager

Basic Usage

options[:target] = %w{target1.rb target2.rb target3.rb}
Origen.regression_manager.run(options) do |options|
  Origen.target.loop(options) do |options|
    Origen.lsf.submit_origen_job "generate regression.list -t #{options[:target]}"
  end
end

Instance Method Details

#copy_regression_fileObject

We want the reference workspace to run the same regression as the local workspace, so copy the current version of the regression command file across.

#run(options = {}) ⇒ Object

Serves to execute a regression. Any block of code passed to this method will receive regression check

Parameters:

  • options (Hash) (defaults to: {})

    Options to customize the run instance

Options Hash (options):

  • :target (Array)

    String Array of target names on which to run regression

  • :build_reference (Boolean) — default: true

    Build reference workspace automatically

  • :send_email (Boolean) — default: false

    Send results email when regression complete

  • :email_all_developers (Boolean) — default: false

    If sending email, whether to email all developers or just user

  • :report_results (Boolean) — default: false

    Whether to report results inline to console
