Should be fixed, please verify.

you're gone in an infinite loop using "attempt", which is running more tests than those in the example tests.
Print the inputs to the console (possibly with a "flush" option set to true. See in your language if it exists)

What language are you using? My test suite in python prints out inputs for each test. If in your language this is not the same, you can actually print to console anytime you want and show the inputs to yourself that way.

Can you fix the testing code?

Otherwise I fear there is little I can do and this issue has been reported multiple times already.
