#report(count, &block) ⇒ Object #report(count, seed, &block) ⇒ Object

Initializes the report run and yields itself for further reporting. The block is required, so that the reporter can manage cleaning up after the run.

Warning:

The seed argument is an internal API and is not guaranteed to be supported in the future.

Examples:


reporter.report(group.examples.size) do |r|
  example_groups.map {|g| g.run(r) }
end

Parameters:

  • count (Integer) —

    the number of examples being run

  • seed (Integer) (defaults to: nil) —

    the seed used to randomize the spec run

  • block (Block) —

    yields itself for further reporting.
