#group(name = nil, options = {}) {|@current_group| ... } ⇒ Object Also known as: add_group

IG-XL doesn't have a formal instance group type and instead declares them anonymously whenever test instances of the same name appear consecutively in the test instance sheet. However when it comes to generating a test program life becomes much easier if we have a way to explicitly declare instances as part of a group - this makes duplicate tracking and sorting of the test instance sheet much easier.

Use this method to generate instance groups via a block. Within the block you should generate instances as normal and they will automatically be assigned to the current group. Note that the name of the instances generated within the group is discarded and replaced with the name of the group. Origen automatically appends “grp” to this name to highlight instances that were generated as part of the group.

test_instances.group("erase_all_blocks") do |group|
  # Generate instances here as normal
  test_instances.functional("erase_blk0")
  test_instances.functional("erase_blk1")
end

The group object is passed into the block but usually you should not need to interact with this directly except maybe to set the name if it is not yet established at the point where the group is initiated:

test_instances.group do |group|
  # Generate instances here as normal
  group.name = "group_blah"
end

A common way to generate groups is to create a helper method in your application which is responsible for creating groups as required:

def group_wrapper(name, options)
  if options[:by_block]
    test_instances.group(name) do |group|
      yield group
    end
  else
    yield
  end
end

In that case the group argument becomes quite useful for branching based on whether you are generating a group or standalone instances:

group_wrapper(name, options) do |group|
  if group
    # Generate group instances
  else
    # Generate standalone instances
  end
end

Yields:

  • (@current_group)
