* Enable features for invasive testing such as introspection functions and
* hooks for fault injection. This enables additional unit tests.
*
* Merely enabling this feature should not change the behavior of the product.
* It only adds new code, and new branching points where the default behavior
* is the same as when this feature is disabled.
* However, this feature increases the attack surface: there is an added
* risk of vulnerabilities, and more gadgets that can make exploits easier.
* Therefore this feature must never be enabled in production.
