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.
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.
Most of those languages are open source. Any decent project should have their test cases in said repo, otherwise I would be pretty concerned.
- Python‘s regex tests
- PHP‘s regex tests
- Perl‘s regex tests looks really extensive
- Open JDK‘s unit tests (an open source flavour of Java)
- Ruby‘s regex tests
- Mono‘s regex tests (open source version of .NET)
- .NET Core‘s regex tests
- RE2‘s tests (C++ regex engine developed at Google)
- C test suite (developed by AT&T Research)
- PCRE regex tests (Perl Compatible Regular Expressions C library)
I also found an extensive chart on this page which might be of some help to you.
To have a complete list on one page, I’ve found the ones omitted from the accepted answer:
Additional regex test suites for additional languages:
- D’s standard library regex tests
- Go’s regex tests
- GNU grep’s tests (Command line C regex engine)
- regex-posix-unittest (POSIX regex test suite written in Haskell)
- ICU’s regex tests (C/C++ and Java libraries for Unicode, look for files named
- .NET Core Framework regex tests (C#)
- Rust’s regex tests
- TCL’s regex tests (look for the
- TRE’s regex tests (C regex engine which aims for strict POSIX compliance)
- Regfuzz (C toolkit for testing regular expression robustness using randomly generated and invalid regexes)
