• One random test is insufficient

• mocha + chai should be enabled

Everything's working correctly now.

The description needs to include that the number of movies is limited, as with a large number of movies this is NP complete and a good solution would be much outside the bounds of a kata :)

I think that random test cases is not the best idea. It seems that some of the solutions willl be invalid. Because they will pass first test case.

The Node class is not defined in the tests. To use the run tests button, one has to define their own Node.

Remark: JavaScript preloads currently only work on submit.

The Node class is already defined and preloaded for you. You shouldn't need to define it yourself. Just use it as explained in the last part of the description.

Fixed it. Thanks!

I'm also getting this error. What's up with writting your own node class? This doesn't make any sense. You're supposed to get your node object as a parameter.

Last test expects false but if fails returns wrong message :
'Should return true for a big tree with leaves at different levels'

I was getting that error as well, but then it went away. Not sure what happened.

yeah, I had that error too. You should your own Node Class, it should take three parameters Node(value, left, right)
