class Tryouts

def tryout(name, dtype=nil, command=nil, &block)

NOTE: This is a DSL-only method and is not intended for OO use.

* +b+ is a block definition for the Tryout. See Tryout#from_block
* +command+ when type is :cli, this is the name of the Rye::Box method that we're testing. Otherwise ignored.
* +type+ is the default drill type for the Tryout. One of: :cli, :api
* +name+ is the name of the Tryout
Create a new Tryout object and add it to the list for this Tryouts class.
