/*****************************************************************************
*
* FILE-LOCAL TESTING MACROS
*
* Purpose:
*
* 1) Upon test failure, goto-jump to single-location teardown in test
* function. E.g., `error:` (consistency with HDF corpus) or
* `failed:` (reflects purpose).
* >>> using "error", in part because `H5E_BEGIN_TRY` expects it.
* 2) Increase clarity and reduce overhead found with `TEST_ERROR`.
* e.g., "if(somefunction(arg, arg2) < 0) TEST_ERROR:"
* requires reading of entire line to know whether this if/call is
* part of the test setup, test operation, or a test unto itself.
* 3) Provide testing macros with optional user-supplied failure message;
* if not supplied (NULL), generate comparison output in the spirit of
* test-driven development. E.g., "expected 5 but was -3"
* User messages clarify test's purpose in code, encouraging description
* without relying on comments.
* 4) Configurable expected-actual order in generated comparison strings.
* Some prefer `VERIFY(expected, actual)`, others
* `VERIFY(actual, expected)`. Provide preprocessor ifdef switch
* to satisfy both parties, assuming one paradigm per test file.
* (One could #undef and redefine the flag through the file as desired,
* but _why_.)
*
* Provided as courtesy, per consideration for inclusion in the library
* proper.
*
* Macros:
*
* JSVERIFY_EXP_ACT - ifdef flag, configures comparison order
* FAIL_IF() - check condition
* FAIL_UNLESS() - check _not_ condition
* JSVERIFY() - long-int equality check; prints reason/comparison
* JSVERIFY_NOT() - long-int inequality check; prints
* JSVERIFY_STR() - string equality check; prints
*
*****************************************************************************/
