// Force-included before all Javelin sources to suppress test compilation.
// Redefine TEST macros to produce no function body, avoiding compilation
// of test code that references RUN_TESTS-only APIs.
#ifndef JAVELIN_SUPPRESS_TESTS_H
#define JAVELIN_SUPPRESS_TESTS_H
// Override the test macros from unit_test.h.
// Original (without RUN_TESTS):
// TEST_BEGIN → namespace UnitTestNNN { static void Test() {
// TEST_END → } }
//
// Our override makes Test() an empty function, then opens a dead namespace
// that swallows the original test body code until TEST_END closes it.
// The swallowed code goes into a struct with an unused template, so it
// never gets instantiated or compiled.
