/**
* Helper macro that wraps a statement in a block that sets up the mock for
* CHRE_ASSERT and expects it to be called at least once. This allows for
* verification that the code to be tested throws an expected assertion failure,
* and also handles the failure gracefully when assertions are compiled out.
* Triggered assertions are logged using LOGI, so they can be manually checked
* in the test output.
*
* Example:
* @code{.cpp}
* TEST(DynamicVector, InsertToSparseIndexFails) {
* DynamicVector<int> vector;
* EXPECT_CHRE_ASSERT(EXPECT_FALSE(vector.insert(5));
* }
* @endcode
