Regular Expression Engine Testing

I wrote my own Regular Expression Engine. Does anybody know how to test 开发者_C百科it, I can go ahead the test with couple of Regular Expression and some input data. but I need some huge list of regular expressions to test with.

PCRE has some tests as well.

The Boost.Regex and Boost.Xpressive test suites are a good place to start.

Is your code compatible with unit testing? Testing the components that make up the whole might have some value.
