/*
 * This header defines an implementation of the OPENER_ASSERT macro that
 * can be used with Cpputest unit tests to confirm an assertion fails
 * under given conditions. It is conditionally included in the application
 * code when unit tests are enabled through the Cmake configuration; it should
 * not be included in the Cpputest unit test code.
 *
 * The intent is to create an assertion implementation that both immediately
 * stops execution after an assertion failure, as should normally be the
 * case, and is detectable from the unit test code. This is accomplished via
 * setjmp() and longjmp(), approximating the behavior of a C++ exception,
 * where an OPENER_ASSERTION failure results in a longjmp() back to the
 * unit test code, which then verifies that an assertion failure occurred.
