It feels like we removed a lot of tests and did not add new ones.

I don't test print_list() function. We do need test it ? @cclauss


for i in range(5):
assert len(circular_linked_list) == i
circular_linked_list.insert_nth(i, i + 1)

Please delete .print_list() as it is completely redundant.

Hey @shellhub,
Something went wrong with the build.

TravisCI finished with status errored, which means the build failed because of something unrelated to the tests, such as a problem with a dependency or the build process itself.
