+The test system itself requires:

+  - bash(1) version 4.0 or newer
+
+Without bash 4.0+ the tests just refuse to run.

 Some tests require external dependencies to run. Without them, they
 will be skipped, or (rarely) marked failed. Please install these, so
 that you know if you break anything.

+If your system lacks these tools or have older, non-upgradable versions
+of these, please (possibly compile and) install these to some other
+path, for example /usr/local/bin or /opt/gnu/bin. Then prepend the
+chosen directory to your PATH before running the tests.
+
+e.g. env PATH=/opt/gnu/bin:$PATH make test
+
+For FreeBSD you need to install latest gdb from ports or packages and
+provide path to it in TEST_GDB environment variable before executing
+the tests, native FreeBSD gdb does not not work.  If you install
+coreutils, which provides GNU versions of basic utils like 'date' and
+'base64' on FreeBSD, the test suite will use these instead of the
+native ones. This provides robustness against portability issues with
+these system tools. Most often the tests are written, reviewed and
+tested on Linux system so such portability issues arise from time to
+time.

+Currently we do not consider skipped tests as build failures. For
+maximum robustness, when setting up automated build processes, you
+should explicitly skip tests, rather than relying on notmuch's
+detection of missing prerequisites. In the future we may treat tests
+unable to run because of missing prerequisites, but not explicitly
+skipped by the user, as failures.

+Testing installed notmuch
+-------------------------
+
+Systems integrators (e.g. Linux distros) may wish to test an installed
+version of notmuch.  This can be done be running
+
+     $ NOTMUCH_TEST_INSTALLED=1 ./test/notmuch-test
+
+In this scenario the test suite does not assume a built tree, and in
+particular cannot rely on the output of 'configure'. You may want to
+set certain feature environment variables ('NOTMUCH_HAVE_*') directly
+if you know those apply to your installed notmuch). Consider also
+setting TERM=dumb if the value of TERM cannot be used (e.g. in a
+chroot with missing terminfo). Note that having a built tree may cause
+surprising/broken results for NOTMUCH_TEST_INSTALLED, so consider
+cleaning first.
