Mocking Spire.PDF to unittest our application

[berrydictu]

We would like to unittest our application that is using Spire.PDF. For example, we would like to count the number of calls to pdfPageBase.Canvas.DrawString/Rectangle/etc. There seems to be no interface we can mock (with NSubstitute).

Is there a convenient way to mock Spire.PDF objects/classes to be able to unittest our own code without building a lot of proxy classes etc, only for unittesting purposes?

Hi,

Thank you for your inquiry.
Sorry, our product currently doesn‘t have such an interface or method to meet your needs. We deeply apologize for any inconvenience caused.

Thank you for your timely reply.
Are there any plans to add support for this? As dependency injection and testing like this is a common way of work, I think it would be a great value for your product.

Hi,

Thank you for your feedback.
Due to the many functions provided by our product, considering the iteration cycle of the product, supporting this approach as a whole would increase product complexity, so our product cannot provide support for your requirement at the moment. In addition, I asked our R&D team and they suggested that you try implementing your requirements in the form of secondary encapsulation code. We deeply apologize for any inconvenience caused.

Sincerely,
