## ✨ New tool to merge reports
If you run tests on multiple shards, you can now merge all reports in a single HTML report (or any other report)
using the new `merge-reports` CLI tool.
Using `merge-reports` tool requires the following steps:
1. Adding a new "blob" reporter to the config when running on CI:
```js title="playwright.config.ts"
export default defineConfig({
testDir: './tests',
reporter: process.env.CI ? 'blob' : 'html',
});
```
The "blob" reporter will produce ".zip" files that contain all the information
about the test run.
2. Copying all "blob" reports in a single shared location and running `npx playwright merge-reports`:
```bash
npx playwright merge-reports --reporter html ./all-blob-reports
```
