This `struct` provides a namespace for a suite of utility functions that facilitate the creation of BDE‐style test drivers.

== Synopsis

Declared in `<bslmt_testutil.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
struct TestUtil;

== Description

The `callFunc` function, because it's out‐of‐line implementation is in the `.cpp` file, can be used to prevent unwanted inlining in test drivers, particularly useful when testing the stack trace functionality.

| Return the specified `functionPtr` (expected to be a static function pointer) without modification. The value of `functionPtr` is transformed through `identityPtr` so that if the caller is in a different module, the compiler will have no way of knowing that this is an identity function and thus no way of inlining the call.
