## `tsdx test`

This runs Jest v24.x, forwarding all CLI flags to it. See [https://jestjs.io](https://jestjs.io) for options. For example, if you would like to run in watch mode, you can run `tsdx test --watch`. So you could set up your `package.json` `scripts` like:

```json
{
  "scripts": {
    "test": "tsdx test",
    "test:watch": "tsdx test --watch",
    "test:coverage": "tsdx test --coverage"
  }
}
```
