13/*C API TEST FOR Regular Expressions */
14/**
15* This is an API test for ICU regular expressions in C. It doesn't test very many cases, and doesn't
16* try to test the full functionality. It just calls each function and verifies that it
17* works on a basic level.
18*
19* More complete testing of regular expression functionality is done with the C++ tests.
