Run the test. No interaction required.

The test passes if seven short horizontal lines are shown and there is no red visible on the page. The first four lines and the last line must have the same length and be vertically aligned. The fifth line must be twice the length of the others, its left edge aligning with the left of the test slide and its right edge with the right edge of the line above it. The sixth line must be the same length as the last line and its midpoint must be at the same horizontal position as the left edge of the last line.

The 'path' element's 'd' attribute ignores additional whitespace, newline characters, and commas, and BNF processing consumes as much content as possible, stopping as soon as a character that doesn't satisfy the production is encountered.

Various black path segments are rendered that each demonstrate one of the parsing rules. Each path segment is placed on top of a similar path segment that lacks the particular parsing rule that is being tested. Test passes if no red is visible.
