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