How to test prawn-templates?

[Danillo Souza]

hey guys,

I'm using prawn-template to change a couple of PDFs we have here but I'm not sure what's the best way to test it.

I basically want to make sure that I'm calling the methods that changes my PDF file.

Prawn::Document.generate('/tmp/pdf.pdf', :margin => [0,0,0,0], template: '/path/to/my/template.pdf')) do
          go_to_page 1

          image '/path/to/image.png', at: [100, 100], fit: [105, 35]
end

Is there a chance I can assert that I'm calling `go_to_page` and `image` methods?

Cheers,
