executing afterEach in multiple specification files

Question

executing afterEach in multiple specification files

Seeking a solution to execute shared code across tests in various spec files in Playwright using TypeScript. Specifically, I need to upload test results based on the testInfo. While I know that fixtures can achieve this, it's not the most efficient option. With fixtures, I have to specify them for each test, even if I don't need to reference them directly in my tests. This increases the risk of forgetting to include the fixture in new tests or accidentally removing it during cleanup.

I've noticed that importing files containing beforeAll or afterAll will work as intended. However, attempting the same with beforeEach or afterEach only triggers the code once, rather than before and after each test individually.

Is there a method to replicate the functionality of beforeEach or afterEach in multiple spec files without adding unnecessary code to each test?

To simplify the process, I recommend using a shared file that you import into each test file and invoke. This method is effective for utilizing beforeEach and afterEach. However, when it comes to beforeAll and afterAll, they are specific to each spec file. They will be executed once per spec file, rather than for the entire group of tests. If you prefer these hooks to run only once for all specs, consider implementing globalSetup and globalTeardown.

Shared file:

import { test } from '@playwright/test';

export function setupGlobalHooks() {
  test.beforeAll(() => {
    // Actions before running all tests
  });

  test.beforeEach(() => {
    // Actions before running each test
  });

  test.afterAll(() => {
    // Actions after running all tests
  });

  test.afterEach(() => {
    // Actions after running each test
  });
}

An example spec file:

import { test } from "@playwright/test";
import { setupGlobalHooks } from "./global";

setupGlobalHooks();
...

Alternatively, you can create a set of shared functions to include in each spec's beforeEach and afterEach. However, I find the former approach preferable as it clearly indicates whether common hooks are missing.

A feature request has been submitted for this issue, so there may be an improved solution in the future. It's worth noting that the workaround mentioned in the second post seems functional but may fail if using a single worker. In such cases, both *All and *Each hooks will only execute during the first spec run.
