I'm getting this failure message,

Must allow to set code 'abnyyvuciwhtdi': no id given

Dispite all my test cases passing. What does that 'no id given' message mean?

My test cases ( that are all green )

Test.expect_error { Code.a }
Test.expect_no_error { Code.a = 10 }
Test.expect( Code.a == 10 )

Test.expect_error { Code.valghpf }
Test.expect_no_error { Code.valghpf = 22 }
Test.expect( Code.valghpf == 22 )

Test.expect_error { Code.nil }
Test.expect_no_error { Code.nil = 22 }
Test.expect( Code.nil == 22 )
