From 17ab08bcf0ae27ec6a1f07766080ebfbea8837d9 Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Wed, 16 Nov 2016 16:34:17 +0100 Subject: tests: Move HTTP server to (guix tests http). * tests/lint.scm (%http-server-port, %local-url) (%http-server-socket, http-write, %http-server-lock) (%http-server-ready, http-open, stub-http-server) (call-with-http-server, with-http-server): Move to (guix tests http). Adjust tests for %HTTP-SERVER-SOCKET as a promise and %LOCAL-URL as a parameter. * guix/tests/http.scm: New file. * Makefile.am (dist_noinst_DATA): Add it. (GOBJECTS): Add .go files for all of $(dist_noinst_DATA). (make-go): Depend on $(dist_noinst_DATA). --- Makefile.am | 8 ++-- guix/tests/http.scm | 120 ++++++++++++++++++++++++++++++++++++++++++++++++++++ tests/lint.scm | 114 ++++++++----------------------------------------- 3 files changed, 141 insertions(+), 101 deletions(-) create mode 100644 guix/tests/http.scm diff --git a/Makefile.am b/Makefile.am index 908eaf6ec0..5d3639747f 100644 --- a/Makefile.am +++ b/Makefile.am @@ -171,8 +171,8 @@ MODULES += \ endif BUILD_DAEMON_OFFLOAD -# Internal module with test suite support. -dist_noinst_DATA = guix/tests.scm +# Internal modules with test suite support. +dist_noinst_DATA = guix/tests.scm guix/tests/http.scm # Linux-Libre configurations.
