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.

(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?

Below you can see an excerpt from the description/sample tests in python, I replaced space characters by dots to make it easier to compare. The expected line length is 30 characters.

(1)"nunc,..at..aliquet.orci..Fusce"
(2)"at...dolor...sit...amet..felis"

The sequence of spaces in line (1) is: 2, 2, 2.
The word "at" at the beginning of line (2) could be appended at the end of line (1) if each sequence of 2 spaces would be replace by 1 space, couldn't it?

SMH calculating max() three times for the same values is not according to the DRY programming principle

I think I'm making a mistake with the random tests, because 550 warriors were able to solve the task in Python:

This is the error message:

identifier = 'jklmnJKLMJKLijklm'
target_case = 'camel'
Expected: jklmn_j_k_l_m_j_k_lijklm Instead got: jklmn_jKLMJKLijklm: 'jklmn_jKLMJKLijklm' should equal 'jklmn_j_l_m_j_k_lijklm'

The expected result looks like snake case although it should be camel case. My result is neither ‘jklmn_j_k_l_m_j_k_lijklm’ nor ‘jklmn_j_k_l_m_j_k_lijklm’ but ‘jklmnJKLMJKLijklm’.

Can someone please help me?
