 Some tests require external dependencies to run. Without them, they

 notmuch-test script). Either command will run all available tests.

+Currently we do not consider skipped tests as build failures. For
+maximum robustness, when setting up automated build processes, you
+should explicitely skip tests, rather than relying on notmuch's

+unable to run because of missing prerequisites, but not explicitely
