如何在 React 测试库中全局设置 waitFor 选项？

Question

I was taking a look to the waitFor documentation and I was wondering if there is any way to configure it globally, for example in the jest.config or in the command used to launch the test suite?

I need to increase the timeout in every test and it is a bit annoying.

Answer 1

Per the documentation , the configuration option for the timeouts on the various asynchronous utilities is asyncUtilTimeout :

asyncUtilTimeout

The global timeout value in milliseconds used by waitFor utilities. Defaults to 1000ms.

You can configure this using the configure function, eg in a setupTests.js file:

import { configure } from "@testing-library/react";

configure({ asyncUtilTimeout: 5000 });

Answer 2

You could create a helper function, no?

export function wrappedWaitFor(cb, opts = {}) {
  waitFor(cb, { ...opts, timeout: 10000 });
}
