# @as-pect/json-reporter

Legacy JSON file reporter for `as-pect` Test sessions.

## Use from the CLI

```sh
npx asp --json
```

The reporter writes one `.json` file per test entry, next to that entry, and skips empty Suite reports. Use `@as-pect/ctrf-reporter` / `asp --ctrf` when a consumer expects the Common Test Report Format.

## Programmatic use

```ts
import JSONReporter from "@as-pect/json-reporter";

const reporter = new JSONReporter();
```

Pass an output root to the constructor when relative `SuiteReport.fileName` values should resolve somewhere other than `process.cwd()`.
