C# tests generate warnings:

tests/Fixture.cs(41,31): warning CS0168: The variable 'e' is declared but never used
tests/Fixture.cs(56,31): warning CS0168: The variable 'e' is declared but never used
tests/Fixture.cs(71,31): warning CS0168: The variable 'e' is declared but never used
tests/Fixture.cs(86,31): warning CS0168: The variable 'e' is declared but never used

That's clever, but damn is that going to be tough to debug O_o
Can you explain it?

フインヤと思う💀💀

Can you explain how this works?

3х3 решается быстро генетикой, дальше все хуже

COBOL translation.

OP solved it closing ~~

tests/Fixture.cs(41,31): warning CS0168: The variable 'e' is declared but never used

Needs more test cases (at least in Java). My deliberately-bad solution passes the random tests by luck (occasionally).

I like how succinct and readable this is, but if you're going to do repeated string concanetations it's good practice to use a StringBuilder. Otherwise, this is great ^_^

Ruby 3.0 should be enabled, read this to learn how to do it

Please organize the structure of test fixture as following (although it has been mentioned in the attached link, I'm repeated here again)

describe "<This message should describe the categories of test groups inside this block>" do
  it "<A short message describing this test group>" do
    expect(...).to eq(...) #Assertions
    #Or Test.assert_equals(user_response, reference_response)
  end
end
