 When I was an architecture developer I tried to.  But when stabilising
a minor version of curl (for example), testing all reverse dependencies
is no option.  But this broke tests for Bazaar for example in stable.
 Or another issue.  Badly written Autoconf systems which will break in
src_test() with a different version of intltool, which is not a direct
dependency.  That pitfall hit me several times in the last years.
 The more, x86 e.g. ranges from embedded Geode platforms to dual core
desktop systems and running the sqlite test suite on the first is no
fun.  As a user I would not accept two hours of build time.
 Test-driven development is great, but not so widely used as one could
wish it to be.

 Arch devs run test suites and won't stabilise if it fails (except some
special cases).
