Hello, I think I found a bug in (srfi srfi-64) module shipped with GNU Guile.
The specification says the following regarding the test-apply: > If one or more specifiers are listed then only tests matching the specifiers > are executed. The specifiers are defined in `Test specifiers' section: > [..] For convenience, a specifier may also be a non-procedure value, which is > coerced to a specifier procedure, as described below for count and name. That means that following should work: (use-modules (srfi srfi-64)) (test-apply 1 (λ () (test-assert #t))) However it does not: Backtrace: In ice-9/boot-9.scm: 1752:10 12 (with-exception-handler _ _ #:unwind? _ #:unwind-for-type _) In unknown file: 11 (apply-smob/0 #<thunk 7fd0803c7300>) In ice-9/boot-9.scm: 724:2 10 (call-with-prompt _ _ #<procedure default-prompt-handler (k proc)>) In ice-9/eval.scm: 619:8 9 (_ #(#(#<directory (guile-user) 7fd0803cac80>))) In ice-9/boot-9.scm: 2836:4 8 (save-module-excursion _) 4388:12 7 (_) In srfi/srfi-64/testing.scm: 947:34 6 (test-apply 1 #<procedure 7fd074b30108 at /home/wolf/src/guile-wolfsden/tests…>) 944:21 5 (test-apply _ #<procedure 7fd074b30108 at /home/wolf/src/guile-wolfsden/tests…>) 688:12 4 (_) 648:2 3 (%test-on-test-begin #<test-runner pass-count: 0 fail-count: 0 xpass-count: 0…>) 266:21 2 (%test-should-execute #<test-runner pass-count: 0 fail-count: 0 xpass-count: …>) 257:17 1 (%test-any-specifier-matches (1) #<test-runner pass-count: 0 fail-count: 0 xp…>) 257:17 0 (%test-any-specifier-matches #<test-runner pass-count: 0 fail-count: 0 xpass…> …) srfi/srfi-64/testing.scm:257:17: In procedure %test-any-specifier-matches: Wrong type to apply: 1 The string variant is also not supported, as in: (use-modules (srfi srfi-64)) (test-apply "t-a" (λ () (test-assert #t))) Resulting in: [..] srfi/srfi-64/testing.scm:257:17: In procedure %test-any-specifier-matches: Wrong type to apply: "t-a" Have a nice day Tomas Volf
