Platform print excel contract
Verification Boundary
The file exercises the rendering boundary with a real Chromium browser and controlled page content.
What This Suite Proves
The checks compare the rendered document or print contract with the supplied browser fixture. They do not stand in for a complete deployed report journey.
What It Does Not Prove
This boundary does not establish all report admission, recipient delivery or source-permission behavior.
Real Dependencies and Test Doubles
Chromium executes the page fixture. File-owned request responses or page content isolate the render behavior from a deployed customer report.
Must Not Be Doubled
Keep Chromium and the output interpretation real. Replacing either with a prebuilt file removes the rendering behavior being checked.
