# Coverage
The parser is tested against [test262], [babel] and TypeScript for conformance.
Note: tests against regexp are disabled for now.
Clone the test files beforehand:
```bash
git submodule update
```
For maintainers, update to the latest remote, run:
```bash
git submodule update --remote
```
## Development
```bash
# full run
cargo coverage
cargo coverage js # for test262
cargo coverage babel # for babel
cargo coverage ts # for typescript
# run in watch
cargo watch -x 'coverage js'
# filter for a file path
cargo watch -x 'coverage js --filter filter-file-path'
```
