Tests for RegExp Unicode property escapes\n\nThis repository hosts a script that generates tests for [Unicode property escapes in ECMAScript regular expressions](https://github.com/tc39/proposal-regexp-unicode-property-escapes), including [property escapes for properties of strings](https://github.com/tc39/proposal-regexp-v-flag).\n\n[The plan](https://github.com/tc39/test262/issues/950) is to update the script every time the Unicode Standard is updated (i.e. yearly) and to upstream its output to [Test262](https://github.com/tc39/test262).\n\n## Generating the tests\n\nClone the repository, and then run:\n\n```sh\nnpm install\nnpm run build\n```\n\nThe `output` directory holds the generated test files, ready to be upstreamed to [Test262’s `test/built-ins/RegExp/` directory](https://github.com/tc39/test262/tree/main/test/built-ins/RegExp).\n\nTo run the tests in V8 using [`test262-harness`](https://github.com/bterlson/test262-harness):\n\n```sh\ntest262-harness --test262Dir=\"$HOME/projects/test262\" --hostPath=\"$HOME/.jsvu/v8\" --hostType=d8 --hostArgs='--harmony-regexp-property' $(find output -name '*.js') --threads=4\n```\n\nThis assumes you have [the Test262 repository](https://github.com/tc39/test262) checked out at `~/projects/test262`, and a native V8/`d8` build at [`~/.jsvu/v8`](https://github.com/GoogleChromeLabs/jsvu).\n\n## Author\n\n|
