# Most of the test harness lives in a file hosttest.exp. This is part

# of the host-side infrastructure and gets installed in the directory

# $(PREFIX)/share/dejagnu. Other packages have to locate the file

# the hard way since the PREFIX is not provided automatically in

# the site.exp file, instead it is necessary to search through the

# build tree's Makefile. In the case of the infrastructure itself

# a shortcut is both possible and desirable because the script may

# not have been installed yet.

# Note that srcdir actually points at the testsuite subdirectory, not

# at the real srcdir.

# Now that the hosttest.exp utilities are available it is possible to do

# There are standard routines ${tool}_start, ${tool}_load, ${tool}_exit

# and ${tool}_version which test harnesses should normally implement.

# In practice runtest only invokes ${tool}_exit and ${tool}_version

# directly, the rest may or may not be invoked from inside the individual

# test scripts.

#

# ${tool}_version is relatively straightforward. The master version

# number is maintained in the configure.in script and is exported to

# the build tree's Makefile. There is a hosttest routine which does the

# hard work because getting the information is common to all host

# packages. The _version routine itself cannot be made completely generic

# because the first output is package-specific.

# ${tool}_load is used to load a test case into the tool. The exact

# meaning is not applicable. However it makes sense to have this

# routine provide an alias for hosttest_run_simple_test which provides

# all the libraries etc. that are going to be needed.
