start(attr_name, *options) click to toggle source

Starts a new task context on test setup and assigns it to a local variable

@overload start(attr_name, task_name, run_spec)

@param [String,Symbol] attr_name the attribute name
@param [String] task_name the name of the orocos task that
  should be assigned to 
@param [Hash] run_spec arguments that should be passed to
  {Orocos.run}. Once Orocos.run is called, there should
  exists a task called task_name

@overload start(attr_name, run_spec)

@param [String,Symbol] attr_name the attribute name as well
  as the orocos task name. See above.
@param [Hash] run_spec arguments that should be passed to
  {Orocos.run}. Once Orocos.run is called, there should
  exists a task called attr_name

Requires the unit test to start a deployment/task at startup and shut it down during teardown. In test methods, the task object can be accessed as the attr_name attribute

@example start a task context and tests that configuration fails

require 'minitest/spec'
require 'orocos/test/component'
describe 'xsens_imu::Task' do
  include Orocos::Test::Component
  start 'task', 'xsens_imu::Task' => 'task'

  def test_configure_fails_if_no_device_is_present
    task.device = ""
    assert_raises(Orocos::StateTransitionFailed) { task.configure }
  end
