Unable to locate TypeScript's before() and after() methods

Having trouble running TypeScript tests with Jest/SuperTest - when running npm test, I encounter the following errors:

Which package am I missing or not importing?

 FAIL  test/test.ts
  ● Test suite failed to run

    test/test.ts:8:3 - error TS2304: Cannot find name 'before'.

    8   before(PlatformTest.bootstrap(Server));
        ~~~~~~
    test/test.ts:9:3 - error TS2304: Cannot find name 'before'.

    9   before(() => {
        ~~~~~~
    test/test.ts:12:3 - error TS2304: Cannot find name 'after'.

    12   after(PlatformTest.reset);

Here are the imports I have used:

import {PlatformTest} from "@tsed/common";
import * as SuperTest from "supertest";
import {Server} from "../src/Server";

Answer №1

Before proceeding, ensure that you have selected the correct global functions in Jest. It's important to note that Jest does not support the use of after() or before(), but instead provides options like afterEach() and beforeEach().

For a comprehensive list of all Jest global functions, please refer to the official documentation: https://jestjs.io/docs/api
