Nice Kata! However, Java tests (random tests) dont really test the solution properly, as there are 99,9% chance that the time chunk will end with seconds. This way, u can just use "...and second(s)", as there are almost never a test ending with days/hours (which needs to be solved through "...days and 3 hours").
I suggest adding some manually writen tests exactly for those cases, otherwise not fully-solved Katas are getting through.

Nice one indeed, i actualy did the smae as you.

expected x to equal y

means that the tests expected y but your code returned x. you are missing a comma after 182 days. please do not raise issues so lightly in the future, ask questions instead.

Error in browser
Expected : 182 days 1 hour, 44 minutes and 40 seconds
to equal : 182 days, 1 hour, 44 minutes and 40 seconds
But in my vscode i get 182 days 1 hour, 44 minutes and 40 seconds
How can this be?

wow

his ahh is not 4q

5q maybe?

The tests are fine, your function's name is formatDuration instead of format_duration. Rename it so the tests find it.

Looks like there is a problem in python tests

it starts with:

import codewars_test as test
from solution import format_duration

but when I run I get:

Traceback (most recent call last):
File "/workspace/default/tests.py", line 2, in
from solution import format_duration
ImportError: cannot import name 'format_duration' from 'solution' (/workspace/default/solution.py)

I wish this used oxford comma :<

This one in shell was great. Techniques were applied like never before.

Otherwise, the duration is expressed as a combination of years, days, hours, minutes and seconds.

There are no months there. Not a kata issue.

I'm a new programmer, I might be wrong, but some test cases do not follow some of of the given instructions

I used a greedy approach so solve the problem because you said "A unit of time must be used "as much as possible. It means that the function should not return 61 seconds, but 1 minute and 1 second instead. Formally, the duration specified by of a component must not be greater than any valid more significant unit of time"

And here you're testing the opposite: "Incorrect answer for seconds=15731080: expected '6 months, 2 days, 1 hour, 44 minutes …' to equal '182 days, 1 hour, 44 minutes and 40 s…'
Isn't month a more significant unit of time than days if it isn't and I'm wrong what criteria do you use to determine "the more significant unit of time"

OP solved it, closing.
