Thanks!

Which programming language? Your post does not make a lot of sense.

Please tell me where/when you are seeing this error and which programming language it is for.

simple check (2.3ms)

1. test simple check (TestNegator)
   fixture:5
   Assertion with == failed
   code: make_negative(-42) == 42
   lhs: -42
   rhs: 42
   stacktrace:

Test case make_negative(-42) == 42
is incorrect. broken.

Good amount / 1

Good is_integer(n)

Beautiful!

Above code returns false for typer.isNumber(1).

How did this pass the unit test?
