| Tests that document policy violation on oversized-images is not triggered, |
| after images are resized to proper size. |
| |
| The initial sizes setting for images all trigger document policy violation. |
| It is expected that 4 violation report and corresponding console messages |
| generated. (content in -expected.txt) |
| |
| After the resize, there should not be any violations triggered. |
| It is expected that non of images on page are replaced by placeholders |
| after resize. (content in -expected.png) |
| --> |
| |
| <!-- Note: give each image a unique URL so that the violation report is |
| actually sent, instead of being ignored as a duplicate. --> |
