From 73fb14c28ae883b6bd22ffdc63d1d59752cb8e0e Mon Sep 17 00:00:00 2001 From: Mathieu Othacehe Date: Tue, 30 Aug 2022 19:22:47 +0200 Subject: tests: image: New test. Add a new image test module to validate the image creation itself. The images structures are validated using guile-parted. Checking the content of those images is out of scope and should be performed in other modules (installation for instance). * gnu/tests/image.scm: New file. * gnu/local.mk (GNU_SYSTEM_MODULES): Add it. --- gnu/tests/image.scm | 270 ++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 270 insertions(+) create mode 100644 gnu/tests/image.scm (limited to 'gnu/tests') diff --git a/gnu/tests/image.scm b/gnu/tests/image.scm new file mode 100644 index 0000000000..99d34b7670 --- /dev/null +++ b/gnu/tests/image.scm @@ -0,0 +1,270 @@ +;;; GNU Guix --- Functional package management for GNU +;;; Copyright © 2022 Mathieu Othacehe +;;; +;;; This file is part of GNU Guix. +;;; +;;; GNU Guix is free software; you can redistribute it and/or modify it +;;; under the terms of the GNU General Public License as published by +;;; the Free Software Foundation; either version 3 of the License, or (at +;;; your option) any later version. +;;; +;;; GNU Guix is distributed in the hope that it will be useful, but +;;; WITHOUT ANY WARRANTY; without even the implied warranty of +;;; MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
