3# Generic build infrastructure for test programs.
4#
5# The code in this file is independent of the implementation of the test
6# programs being built; this file just provides generic infrastructure for the
7# build and the definition of various helper variables and targets.
8#
9# Makefiles should never include this file directly.  Instead, they should
10# include one of the various *.test.mk depending on the specific test programs
11# being built.

23# List of subdirectories containing tests into which to recurse.  This has the
24# same semantics as SUBDIR at build-time.  However, the directories listed here
25# get registered into the run-time test suite definitions so that the test
26# engines know to recurse into these directories.
27#
28# In other words: list here any directories that contain test programs but use
29# SUBDIR for directories that may contain helper binaries and/or data files.

38# programs built by the Makefile and is installed into TESTSDIR.  This is the
