  There are at least some docs online:

http://gcc.gnu.org/wiki/TestCaseWriting
http://gcc.gnu.org/wiki/HowToPrepareATestcase
http://gcc.gnu.org/onlinedocs/gccint/Testsuites.html#Testsuites

  The DejaGnu manual is available online
(http://www.gnu.org/s/dejagnu/#documentation), although it's not very
GCC-specific; the most useful bit is the list of command-line options
(http://www.gnu.org/s/dejagnu/manual/x844.html#optiondefs) that you can pass
by setting RUNTESTFLAGS="..." on the 'make check' command-line.  If you're
having real trouble understanding what's going on in a test script, setting
RUNTESTFLAGS="-v -v -v --strace 30" will show you all the tcl commands being
executed in the log file.

  And as Ian says, most people just copy how it's done in existing scripts.
