# node:test

> Node's test runner API, run with elide test.

`node:test` provides Node's tests, suites, hooks, test context, and mocks; run test files with `elide test`.

```bash
elide test ./math.test.mjs
```

## Differences from Node

- `elide run` registers tests without running them and prints the `elide test` command to use.
- `run()`, `mock.module()`, and the `snapshot` serializer setters throw `ERR_METHOD_NOT_IMPLEMENTED`.
- Snapshot assertions are not available.
