This is mainly for my own use, so it is not designed to be user-friendly. If anyone else wants to use it for some reason, just wait until "tests not yet loaded" and "tests not yet completed" get down to zero, then click the pass/fail button for any test it shows where it cannot work out the answer (or use the y/n keys to choose for the magenta-highlighted case), then use the buttons at the bottom to collect all the results.

Test name Test case Pass? Fail? Notes

(Submissions will tend to be ignored unless there is a good reason why they won't be, so don't use this form unless there is such a reason.)
