1# Writing tests 2 3Undici is tuned for a production use case and its default will keep 4a socket open for a few seconds after an HTTP request is completed to 5remove the overhead of opening up a new socket. These settings that makes 6Undici shine in production are not a good fit for using Undici in automated 7tests, as it will result in longer execution times. 8 9The following are good defaults that will keep the socket open for only 10ms: 10 11```js 12import { request, setGlobalDispatcher, Agent } from 'undici' 13 14const agent = new Agent({ 15 keepAliveTimeout: 10, // milliseconds 16 keepAliveMaxTimeout: 10 // milliseconds 17}) 18 19setGlobalDispatcher(agent) 20``` 21
