Easy way to stub out aspects?

[gerard-kelly-lu]

I'm trying to ensure that the correct commands are passed to combine_options in my application (eg. adding text).

However, I won't have ImageMagick available on my CI server so need to stub out any commands I make. Currently when I call combine_options I get an executable not found error.

Thanks in advance for any help.

You could override MiniMagick::Tool#call to be a no-op:

class MiniMagick::Tool
  def call(*args)
  end
end
