How do I modify the directory for storing comparison screenshots in Playwright?

Answer

Sure, you can easily change the directory where toHaveScreenshot saves comparison screenshots in Playwright. This is done by modifying the playwright.config.ts file.

Here's how you can do it:

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

export default defineConfig({
  outputDir: 'custom-snapshots-directory',
});

In this example, outputDir is set to 'custom-snapshots-directory'. You can replace this with any directory name that suits your project.

When you run your tests, all generated comparison screenshots will be saved in the specified directory (custom-snapshots-directory). Make sure this directory exists before running your tests to avoid errors.

Each test file will have its own separate snapshots directory. For instance, if you have a test file named example.spec.ts, Playwright Test will create a corresponding snapshots directory named example.spec.ts-snapshots. This helps keep snapshots organized and associated with their respective test files.

Don't forget to commit these snapshot directories to your version control system (like Git) so they're properly tracked and reviewed as part of your project's codebase.

By following these steps, you can easily change the directory where toHaveScreenshot saves comparison screenshots in Playwright.
