How do I set up an HTML reporter for Playwright Test with Java?

Answer

To set up an HTML reporter for Playwright Test with Java, follow these steps:

1. Install the Playwright Test library.

2. Create a playwright.config.ts file in your project's root directory.

3. Define a reporter option in the configuration file:

   import { defineConfig } from '@playwright/test';
   
   export default defineConfig({
     reporter: [['html', { outputFolder: 'my-report' }]],
   });

   This sets up an HTML reporter that generates reports in the my-report folder.

4. If you want to upload attachments from a data folder to another location, use the attachmentsBaseURL option:

   import { defineConfig } from '@playwright/test';
   
   export default defineConfig({
     reporter: [['html', { attachmentsBaseURL: 'https://ray.run/' }]],
   });

5. To open the last test run report quickly, use this command:

   npx playwright show-report

   If there is a custom folder name specified in your configuration file (e.g., my-report), use this command instead:

   npx playwright show-report my-report

Note that the HTML reporter does not support merging reports generated across multiple shards into a single report. However, third-party solutions can help with this issue.
