3904e809b2 Add two test cases for shortcut logic used when one operand is zero and
the other is also the target.

241f524238 Fix a bogus t_malloc_fail in one of the mpi_add_abs() tests.
Add several subtraction test cases and modify some others to better
exercise the carry logic, which is far more complex for subtraction than
for addition.

Add test cases where the target is the same MPI as one or both operands.

8d0e24dee7 Remove the "trailing garbage" version of the mpi_cmp() test. It would
be better to systematically pad MPIs used in all tests with garbage.

Greatly expand the number of mpi_cmp() tests to cover all possible
combinations of same or different sign, same or different msb and same
or different magnitude.

f18b915b67 Fix the "x = a + b" allocation failure test. Since a and b were
equal, mpi_sub_abs() would return early and the test would never
exercise the mpi_grow() call which is intended to fail.

e21452d0c7 Add a few tests for subtraction. They're not particularly well thought
out, because currently subtraction does not work at all, but they work
well enough in the sense that they fail with the current implementation.

03867777c6 Add numerous tests, mostly for allocation failures and edge conditions.
Add a t_compare_mpi() predicate which checks that two MPIs have the same
value (but not necessarily the exact same representation).
Clean up and improve existing tests.

7b6b493509 Declare t_malloc_fail_after. 2014-12-29 23:49:50 +00:00
Dag-Erling Smørgrav
3ec87c7a8c Introduce t_malloc_fail_after: if non-zero, it serves as a countdown to
setting t_malloc_fail.  Also, enforce t_malloc_fail in realloc(), but not
before checking that the argument was valid.

b2ec312d9f Link each test with only the libraries it needs. This avoids rebuilding
every single test whenever any of the libraries changes.

7a09b0638f I had forgotten that t_add_test() is actually a printf()-like variadic
function, which obviates the need for asprintf() in the string comparison
and equality tests.

82e32027af Move the decision of whether to check for memory leaks from the malloc()
code to the driver and allow an environment variable to override the
default (on unless coverage is enabled).

56eccb99fe Add two utility functions which check if a string contains something that
can be interpreted as either true or false.  Use this instead of a basic
non-NULL test for the CRYB_PERFTEST check.

eb10ce6d05 If the test case changes desc, it *must* point to an allocated buffer

6ed802ddf3 Consistently use #if HAVE_FOO instead of #ifdef HAVE_FOO. The reason is
that AC_CHECK_DECLS([foo]), unlike AC_CHECK_FUNCS([foo]), will always
define HAVE_FOO, so #ifdef HAVE_FOO will always be true even if it is 0.
This commit finally fixes the [bl]e{32,64}{enc,dec} issue on Linux.

20dab3e342 Provisionally include strlcmp(), although it is not (currently) used
anywhere.  Opinion is divided as to whether this is useful, or whether
its usefulness is outweighed by its awkwardness.  Still, we have it, so
we may as well commit it.

1f0fd8d9fe Create an additional test case which always runs after cleanup and checks
for memory leaks.  It may be necessary to make this optional at some point,
but for now, none of our tests leak memory.

64a2da2b84 Refactor the malloc() etc code to reduce code duplication.
Introduce a t_malloc_fatal flag that makes unintentional allocation
failures fatal.  This reduces the need for error handling in tests.

Enable that flag in t_main().  Test programs that don't want it can
override it in t_prepare().

c658232e3e && is subject to shortcut evaluation, so the second test will not run
if the first failed.  The ultimate outcome is the same, but using &
instead ensures that, when in verbose mode, we also get output from
the second test.
