How do I pass data from tests to the global teardown using projects in Playwright?

Answer

Sure, you can pass data from tests to the global teardown using projects in Playwright. Here's how you can do it:

Setup and Cleanup Projects

First, define a setup project and a cleanup project in your Playwright configuration file (playwright.config.ts). The setup project prepares data or resources for your tests, while the cleanup project tidies up these resources after all tests have run.

// playwright.config.ts
module.exports = {
  projects: [
    {
      name: 'Setup',
      testMatch: /global.setup\.ts/,
    },
    {
      name: 'Cleanup',
      testMatch: /global.cleanup\.ts/,
    },
  ],
};

Project Dependencies

Next, use testProject.dependencies to specify which projects depend on each other. In this case, your cleanup project depends on your setup project.

// playwright.config.ts
module.exports = {
  projects: [
    {
      name: 'Setup',
      testMatch: /global.setup\.ts/,
    },
    {
      name: 'Cleanup',
      testMatch: /global.cleanup\.ts/,
      dependencies: {
        'Setup': { mode: 'before' },
      },
    },
  ],
};

By setting up this dependency relationship, any data or resources set up in the setup project will be accessible in the global teardown.

Remember, using globalSetup and globalTeardown alone won't produce traces or artifacts. If you want to generate traces and artifacts during your testing process, use project dependencies instead.
