this is a terrible workaround that works:
import { State, getState } from "jest-circus";
type GlobalKey = keyof typeof global;
let jestStateSymbol: GlobalKey | undefined;
function findStateSymbols(): GlobalKey[] {
return Reflect.ownKeys(global).filter(
(key) => key.toString() == "Symbol(JEST_STATE_SYMBOL)"
) as GlobalKey[];
}
/** jest-circus state handling is a clown town
* See https://github.com/jestjs/jest/issues/15018 for more information
*
* This method is a work-around which grabs the correct state object
*/
export function getJestState(): State {
// If we have successfully found state before, keep using the symbol.
if (jestStateSymbol) return global[jestStateSymbol];
/* there can be 0-2 state symbols:
0: state not yet initialized
1: only `describe` invocations has led to updated / accessed state, OR, getState was called by another module
2: both `describe` and another module has accessed state via getState. */
for (const symbol of findStateSymbols()) {
const state: State | undefined = global[symbol];
// undefined? keep looking
if (!state) continue;
// root block? likely the wrong one. Keep looking
if (!state.currentDescribeBlock.parent) continue;
// we found it? remember it going forward
jestStateSymbol = symbol;
return state;
}
// didn't find anything? Just return the root state (which getState always returns, because of the bug).
return getState();
}
from jest.
