I'm building a regex helper at http://www.debuggex.com. The amount of detail I want to show requires me to write my own parser and matcher.
To make sure my parser and matcher work correctly, I've written my own unit tests for the Javascript flavor of regexes, but these only cover edge cases I know about. I would like to use a standard test suite, and was recently pointed to http://hg.ecmascript.org/tests/test262/summary, which I will be using.
My question is, where can I find such test suites for other regex flavors? I'd like to support other flavors in the future. I have not been able to find anything by googling ("test" pollutes the results with regex testers). I am looking for test suites for the languages python, php, perl, java, ruby, and .net.
