23 Mnemonic: tools_static_test.c
24 Abstract: Unit tests for the RMr tools module. This file is a static include
25 that is pulle in at compile time by the test driver. The driver is
26 expected to include necessary rmr*.h and test_support files before
27 including this file. In addition, a context struct, or dummy, must
28 be provided based on the type of testing being done.
