Automated document conversion testing

A non-transitory computer-readable storage medium storing executable computer program instructions for automated document conversion testing, the computer program instructions comprising instructions for:

• for a plurality of document pages of a multi-page document:
• converting an entire received document page into a single source image;
• converting the entire document page into a set of markup language page elements;
• generating, for each of a plurality of target software platforms, a single rendered image corresponding to the entire received document page, each rendered image generated from the set of markup language page elements displayed on a corresponding target software platform, each target platform characterized by a combination of at least a web browser and an operating system;
• determining, for each of the plurality of target software platforms, a correlation factor between the source image and the rendered image, wherein the correlation factor indicates a page fidelity between the source image and the rendered image for that target platform;
• obtaining a threshold correlation factor for the document page, the threshold correlation factor representing a common fidelity criterion for the document page across the plurality of target software platforms;
• and
• responsive to the correlation factor for a given target platform exceeding the threshold correlation factor, validating the markup language page elements for the given target platform.

A system for automated document conversion testing, the system comprising:

• a processor;
• a first converting module for converting an entire received document page into a single source image;
• a second converting module for converting the entire document page into a set of markup language page elements;
• an image-generation module for generating, for each of a plurality of target software platforms, a single rendered image corresponding to the entire received document page, each rendered image generated from the set of markup language page elements displayed on a corresponding target software platform, each target platform characterized by a combination of at least a web browser and an operating system;
• a determination module for determining, for each of the plurality of target software platforms, a correlation factor between the source image and the rendered image, wherein the correlation factor indicates a page fidelity between the source image and the rendered image for that target platform;
• and
• a validation module for validating the markup language page elements for the given target platform in response to the correlation factor exceeding a threshold correlation factor for the document page, the threshold correlation factor representing a common fidelity criterion for the document page across the plurality of target software platforms.
