# File 'lib/baretest.rb', line 24

def BareTest(&block)
  BareTest.instance_eval(&block)
end

.expanded_require_path(name, extensions = nil) ⇒ Object

Returns the absolute path to the file require would load, also see Kernel#require_path

def expanded_require_path(name, extensions=nil)
  path = require_path(name, extensions)
  path && File.expand_path(path)
end

.load_into(name, mod = nil) ⇒ Object

Will load the given file like load (but accepts files without .rb in the end, like require), but evaluate it into the module given with the second arg (defaulting to Module.new). It uses Kernel#expanded_require_path with ” and ‘.rb’ as extensions to determine the file to load uses the returned path for error messages (second argument to Module#modul_eval).

Raises:

  • (LoadError)
