Unable to access property 'runnable' of null while running Jest test

After creating a new .spec file, I encountered an issue where the tests inside it are failing with the following error:

    TypeError: Cannot read property 'runnable' of null

      at ret (node_modules/selenium-webdriver/testing/index.js:175:25)
      at ZoneDelegate.Object.<anonymous>.ZoneDelegate.invoke (node_modules/zone.js/dist/zone.js:388:26)
      at ProxyZoneSpec.Object.<anonymous>.ProxyZoneSpec.onInvoke (node_modules/zone.js/dist/proxy.js:128:39)

      at Object.testBody.length.done (node_modules/jest-zone-patch/index.js:51:29)

This issue seems unfamiliar to me and even Google has not provided any solutions yet. Can anyone help identify what might be causing this problem?

Answer №1

During the process of creating a minimal reproduction example to address this inquiry, I came across a questionable import:

import { beforeEach } from 'selenium-webdriver/testing';

This import was automatically added by my development environment and unfortunately led to the problem at hand. Simply removing it resolves the issue :)
