# dangerouslyIgnoreUnhandledErrors&#x20;

* **Type**: `boolean`
* **Default**: `false`
* **CLI:**
  * `--dangerouslyIgnoreUnhandledErrors`
  * `--dangerouslyIgnoreUnhandledErrors=false`

If this option is set to `true`, Vitest will not fail the test run if there are unhandled errors. Note that built-in reporters will still report them.

If you want to filter out certain errors conditionally, use [`onUnhandledError`](/config/onunhandlederror) callback instead.

## Example

```js [vitest.config.js]
import { defineConfig } from 'vitest/config'

export default defineConfig({
  test: {
    dangerouslyIgnoreUnhandledErrors: true,
  },
})
```
