Instance Attribute Details

#mode ⇒ Object

Allows you to define the current mode. The only special value here is :fake. If the mode is :fake, then Imagery::Model#save and Imagery::Model#delete will not actually run.

Examples:


Photo = Class.new(Struct.new(:id))

i = Imagery.new(Photo.new(1001))
i.root = '/tmp'

Imagery::Model.faked {
  assert i.save(File.open('/path/to/image.png'))
}

#faked ⇒ Object

Switches the current mode to :fake.

Examples:

Imagery::Model.mode == nil
# => true

Imagery::Model.faked {
  Imagery::Model.mode == :fake
  # => true
}

Imagery::Model.mode = nil
# => true

def faked
  @omode, @mode = @mode, :fake
  yield
ensure
  @mode = @omode
end

#real ⇒ Object

Switches the current mode to nil. Useful for forcing real saves in your test.

You should do this at least once in your project just to know that all your Imagery::Model#save and Imagery::Model#delete operations actually work.

Examples:

Imagery::Model.mode = :fake

Imagery::Model.faked {
  Imagery::Model.mode == nil
  # => true
}

Imagery::Model.mode = :fake
# => true
