## Test

### Compiling Code

```
npm run build
```

### Examples

See the `examples/` folder.

### Running Tests

```
npm test
```

### Creating Tests

Test `.wasm` files are located in the `test/__fixtures__` directory.
The testing harness compares the parsing output of the `.wasm` file against the snapshot file.
You can use the `npm test -- --updateSnapshot` command to update the snapshot file. This is useful if you have made a change that affects the tests.
