Variables

variable UNDEFINED_VOID_ONLY

const UNDEFINED_VOID_ONLY: Symbol;

Functions

function act

act: {
    (callback: () => Promise<VoidOrUndefinedOnly>): Promise<undefined>;
    (callback: () => VoidOrUndefinedOnly): DebugPromiseLike;
};

Wrap any code rendering and triggering updates to your components into act() calls.
Ensures that the behavior in your tests matches what happens in the browser more closely by executing pending useEffects before returning. This also reduces the amount of re-renders done.
Parameter callback
An asynchronous, void callback that will execute as a single, complete React commit.
