This global and the helpers that use it are not thread-safe.

If thread-safety is needed, a per-thread instance could be used in the multi-threaded test.

Definition at line 14 of file random.cpp.

◆ g_mock_deterministic_tests

bool g_mock_deterministic_tests
extern

Flag to make GetRand in random.h return the same number.
