+Guix also comes with a whole-system test suite that tests complete
+GuixSD operating system instances.  It can only run on systems where
+Guix is already installed, using:
+make check-system
address@hidden example
+or, again, by defining @code{TESTS} to select a subset of tests to run:
+make check-system TESTS="basic mcron"
address@hidden example
+These system tests are defined in the @code{(gnu tests @dots{})}
+modules.  They work by running the operating systems under test with
+lightweight instrumentation in a virtual machine (VM).  They can be
+computationally intensive or rather cheap, depending on whether
+substitutes are available for their dependencies (@pxref{Substitutes}).
+Some of them require a lot of storage space to hold VM images.
+Again in case of test failures, please send @email{}
+all the details.
