thanks, that makes sense

In many random tests, all my test rows match except for a few, e.g.

correct answer:
"'D...'" 9!  Xy14lmTDftz-
YtlLqmJ3Q!  "Gli9..."

my answer:
"'D...'" 9!  Xy14lmTDft-
zYtlLqmJ3Q!  "Gli9..."

In this example, the last letter of line (n) is shifted to the beginning of line (n+1) compared to the reference solution.

Can I assume that if "123\n4567" is a correct solution, then "1234\n567" is also a correct? Is there a rule to make the solution unique?

It would be great if the random tests could be given an individual heading, or even consecutive numbering. Now every random test has the same name: Input text, Correct answer, and Answer returned.

They both serve a purpose. The text is better for direct eyeballing while the string literals are better for copying for further testing/debugging. If one of them was to be removed it's 1, because it is less exact. But there's no need for that, is there. It's not like it's in the way. What can be done though is to combine them by line breaking string literals in some way such that it can still be copied and evaluated, for example:

''.join(
 [ 'Hi, I am some \n'
 , 'text and I need \n'
 , 'to be arranged.'
 ]
)

.. the real problem here in my opinion is that the input text isn't a string literal

(python)
If a test is not passed, result is displayed twice:

1. nicely formatted: Expect/Actual
2. unformatted: Actual/Expected

Input text: 

Hi, I am some text and I need to be arranged.

Line length: 15

* Correct answer: 

Hi, I am some
text and I need
to be arranged.

* Answer returned: 

Hi, I am some 
text and I need 
to be arranged.
: 'Hi, I am some \ntext and I need \nto be arranged.' should equal 'Hi, I am some\ntext and I need\nto be arranged.'

Is it possible to display only 1)?

I want to see the EN DASH character in the text. To do this, I copy the dash character from the sample tests window and execute the following code in python:

import unicodedata
c = "—" # char copied from the sample tests window in browser
print(f"Unicode-Name: {unicodedata.name(c)}")

the python output is "Unicode-Name: EM DASH".
As I understand the description, an EN DASH was used in the text. Can someone please explain what I am misunderstanding?

Python:

passing all fixed test cases but no random test cases. Although it is probably because of my terribly-written, bug-riddled code, the random tests are impossible to debug. The strings are way too long, and it would be really helpful if there were some shorter random strings.

If some one would still find a duplicate, please log an issue instead.

just use aaaaaaaaaa (10+10) with size=15. The goal is to make sure the user doesn't add an empty line at the end.

the maximum line length will never be less than 15 characters;

For the cut edge cases, I'm not even sure what the correct expected result must be. All JS solutions either time out on such cases or give different results.

edit: also, "abcdef ", size=8
