# Coverage
Coverage was generated using [`grcov`](https://github.com/mozilla/grcov). If you have not done so
already, install the `llvm-tools-preview`:
```sh
rustup component add llvm-tools-preview
cargo install grcov --locked
```
After that, you can simply run `coverage.py` to test the `satrs-core` crate with coverage. You can
optionally supply the `--open` flag to open the coverage report in your webbrowser.
