The test suite is just silly/broken.

Matthew Eicholtz on 16 Oct 2017

I agree. I think the test suite needs to be modified.

Alfonso Nieto-Castanon on 16 Oct 2017

it looks fine to me (it sets some bounds without giving away the actual value, perhaps I am missing something?)

good

Improve the test suite..

Ameer Hamza on 2 Jan 2018

The top solutions are not even solving the actual problem.

Jafar Mortadha on 17 Jun 2018

Test suite is very badly made. And the problem is pointless. I hope people who post problems think a little a bit before creating a new problem.

Photon energy calculation is well known equation to the person who learned physics. This problem using not "J" but "eV" as the unit. Take care!

Test Suite needs major improvement. This problem requires way too much research on the part of the user.

Either this should be moved out of the Cody easy section or specific variables should be standardized and provided to the user.

Cannot say enough about how lacking the test suite is.
