# Tests for RegExp Unicode property escapes

This 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).

[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).

## Generating the tests

Clone the repository, and then run:

```sh

npm install

npm run build

```

The `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).

To run the tests in V8 using [`test262-harness`](https://github.com/bterlson/test262-harness):

```sh

test262-harness --test262Dir="$HOME/projects/test262" --hostPath="$HOME/.jsvu/v8" --hostType=d8 --hostArgs='--harmony-regexp-property' $(find output -name '*.js') --threads=4

```

This 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).
