README for nana/test
* Running tests.
use "make check" to run the checkall program which runs the real tests by
using the checkall program.
individual tests can be run as "nana-clg DI.c | check.awk"
* Method.
The test programs include "check.h" which provides a set of macros
which generate output in the form:
output from code@expected output@message\n
This can then be verified by check.awk
* Known Problems.
With -O3 the local variables used in the test are optimised away so
we can't use DI(i>=0) etc. Adding a volatile to the declaration solves
this problem. If you want to see it, add a "-O3 -Dvolatile=" line into
checkall in the list of optimisation options
* Why so many tests (or so few).
A lot of the tests are aimed at testing the compiler rather than the
library. A fair bit of bash testing is needed to find the limitations
of debuggers and compilers, e.g. a debugger that can only set less
than 10,000 breakpoints.
