# pwc-p (orchestration)

`pwc-p` is a command-line executable that implements Currents Orchestration for Playwright. See [Orchestration Setup](/guides/ci-optimization/playwright-orchestration.md) and [Playwright Parallelization](/guides/ci-optimization/playwright-parallelization.md) for detailed guides.

{% hint style="info" %}
**Orchestration** is a two-step process: first run `pwc-p discover` to build a test list, then run `pwc-p run` to execute tests in parallel with load balancing.
{% endhint %}

## Subcommands

* [**`pwc-p discover`**](/resources/reporters/currents-playwright/pwc-p/pwc-p-discover.md) — Runs Playwright test discovery and writes the test list to a file. Accepts Playwright filter flags (`--grep`, `--last-failed`, `--project`, spec paths, and similar).
* [**`pwc-p run`**](/resources/reporters/currents-playwright/pwc-p/pwc-p-run.md) — Starts orchestration and executes tests with load balancing. Accepts [Configuration](/resources/reporters/currents-playwright/configuration.md) options and supported Playwright runtime flags (`-j`, `--timeout`, and similar).

Both commands accept Currents configuration via CLI flags or `currents.config.ts`. See [Configuration](/resources/reporters/currents-playwright/configuration.md#configuration-sources) for recommended setup.

## Basic Workflow

**Full suite (no filters):**

```bash
npx pwc-p run --key <record-key> --project-id <project-id> --ci-build-id <ci-build-id>
```

**Filtered tests (with discovery):**

```bash
# Step 1: Discover tests with optional filters
npx pwc-p discover --pwc-discovery-file tests.txt --grep @smoke

# Step 2: Run orchestrated execution using the discovery file
npx pwc-p run \
  --key <record-key> \
  --project-id <project-id> \
  --ci-build-id <ci-build-id> \
  --pwc-discovery-file tests.txt
```

Or use environment variables to avoid repeating the discovery file path:

```bash
export CURRENTS_DISCOVERY_FILE=tests.txt
npx pwc-p discover --grep @smoke
npx pwc-p run --key <record-key> --project-id <project-id> --ci-build-id <ci-build-id>
```

**Reference:**

* [pwc-p discover](/resources/reporters/currents-playwright/pwc-p/pwc-p-discover.md) — test discovery and filtering options
* [pwc-p run](/resources/reporters/currents-playwright/pwc-p/pwc-p-run.md) — orchestration execution and runtime options
