# Sharded runs

When using native Playwright `--shard` parallelism, the [Last Failed GitHub Action](https://github.com/currents-dev/playwright-last-failed) can fetch and rerun failed tests from the last workflow run.

Step-by-step guide:

<details>

<summary>Add the currents-dev/playwright-last-failed step</summary>

Add a step to the workflow before the test step runs.

<pre class="language-yaml"><code class="lang-yaml">- name: Playwright Last Failed action
<strong>  id: last-failed-action
</strong><strong>  uses: currents-dev/playwright-last-failed@v2
</strong>  with:
    pw-output-dir: basic/test-results
    matrix-index: ${{ matrix.shard }}
    matrix-total: ${{ strategy.job-total }}
</code></pre>

See the [action configuration for details](https://github.com/currents-dev/playwright-last-failed/blob/main/action.yml).

{% hint style="info" %}
For a workflow with a custom CI build ID, see [Custom CI Build ID for Reruns](/getting-started/ci-setup/github-actions/re-run-failed-only-tests/custom-ci-build-id-for-reruns.md).
{% endhint %}

Full examples:

* [rerun-shards-pwc.yml](https://github.com/currents-dev/currents-examples/blob/main/playwright/ci/github-actions/.github/workflows/rerun-shards-pwc.yml) - rerun only the tests that failed in the previous run, using the `pwc` helper command from `@currents/playwright`.
* [rerun-shards-reporter.yml](https://github.com/currents-dev/currents-examples/blob/main/playwright/ci/github-actions/.github/workflows/rerun-shards-reporter.yml) - rerun only the tests that failed in the previous run, using reporter setup in `playwright.config.ts`.
