`i` is a compile-time value that you need to convert into a piece of syntax, so
`syntax->datum` goes the wrong direction. You could use `datum->syntax`, or
even just this:
#lang racket
(define-syntax (gen-testsuite stx)
(syntax-case stx ()
[(_ n)
#`(test-suite
"Automated suite"
#,@(for/list ([i (syntax->datum #'n)])
(with-syntax ([i i])
#`(test-case
(format "Test number ~a" i)
(check = i i)))))]))
