test: Initial testing framework
Configure with --enable-testtools. BLD_ROOT is now the top build directory. Current test requires ttynvt to be started (by root) like # BLD_ROOT/src/ttynvt -d -E -S localhost:1234 -n ttyNVT99 Device and server name parameters must be as shown above. Run tests like $ make -C BLD_ROOT test # Builds the other programs too $ make -C BLD_ROOT/test # Only running tests $ make -C BLD_ROOT/test V=1 RUN_OPTS="--gtest_filter=Test1.t1"
