# SkillPatch skill: azure-resource-manager-playwright-dotnet

This skill provides guidance for using the Azure.ResourceManager.Playwright .NET SDK to perform management plane operations on Microsoft Playwright Testing resources. It covers workspace creation, quota management, name availability checks, and authentication via Azure Identity. It is specifically scoped to ARM/provisioning operations, not test execution.

You (the agent) were given this URL and asked to use this skill. This is a **public** skill — no SkillPatch account, API key, or prior setup is required. Two ways to use it:

**1. Use it right now** — the skill's complete file tree (SKILL.md + all reference files) is inlined below; read `SKILL.md` first, then follow it, consulting the other files as it directs.

**2. Install the exact package onto disk** (recommended if you can run a shell — this reproduces the skill byte-for-byte, including any binary assets that can't be inlined):

```bash
mkdir -p .claude/skills/azure-resource-manager-playwright-dotnet
curl -sSL https://skillpatch.dev/install_skill/azure-resource-manager-playwright-dotnet | tar -xz -C .claude/skills/
```

(`.claude/skills/` is Claude Code's convention; use whatever directory your agent loads skills from.)

  Azure Resource Manager SDK for Microsoft Playwright Testing in .NET. Use for MANAGEMENT PLANE operations: creating/managing Playwright Testing workspaces, checking name availability, and managing workspace quotas via Azure Resource Manager. NOT for running Playwright tests - use Azure.Developer.MicrosoftPlaywrightTesting.NUnit for that. Triggers: "Playwright workspace", "create Playwright Testing workspace", "manage Playwright resources", "ARM Playwright", "PlaywrightWorkspaceResource", "provision Playwright Testing".

# Azure.ResourceManager.Playwright (.NET)

Management plane SDK for provisioning and managing Microsoft Playwright Testing workspaces via Azure Resource Manager.

> **⚠️ Management vs Test Execution**
> - **This SDK (Azure.ResourceManager.Playwright)**: Create workspaces, manage quotas, check name availability
> - **Test Execution SDK (Azure.Developer.MicrosoftPlaywrightTesting.NUnit)**: Run Playwright tests at scale on cloud browsers

## Installation

```bash
dotnet add package Azure.ResourceManager.Playwright
dotnet add package Azure.Identity
```

**Current Versions**: Stable v1.0.0, Preview v1.0.0-beta.1

## Environment Variables

```bash
AZURE_SUBSCRIPTION_ID=<your-subscription-id>  # Required: Azure subscription ID
AZURE_TOKEN_CREDENTIALS=prod  # Required only if DefaultAzureCredential is used in production
AZURE_TENANT_ID=<tenant-id>  # For service principal auth (optional)
AZURE_CLIENT_ID=<client-id>  # For service principal auth (optional)
AZURE_CLIENT_SECRET=<client-secret>  # For service principal auth (optional)
```

## Authentication

```csharp
using Azure.Identity;
using Azure.ResourceManager;
using Azure.ResourceManager.Playwright;

// Local dev: DefaultAzureCredential. Production: set AZURE_TOKEN_CREDENTIALS=prod or AZURE_TOKEN_CREDENTIALS=<specific_credential>
var credential = new DefaultAzureCredential(
    DefaultAzureCredential.DefaultEnvironmentVariableName
);
// Or use a specific credential directly in production:
// See https://learn.microsoft.com/dotnet/api/overview/azure/identity-readme?view=azure-dotnet#credential-classes
// var credential = new ManagedIdentityCredential();
var armClient = new ArmClient(credential);

// Get subscription
var subscriptionId = Environment.GetEnvironmentVariable("AZURE_SUBSCRIPTION_ID");
var subscription = armClient.GetSubscriptionResource(
    new ResourceIdentifier($"/subscriptions/{subscriptionId}"));
```

## Resource Hierarchy

```
ArmClient
└── SubscriptionResource
    ├── PlaywrightQuotaResource (subscription-level quotas)
    └── ResourceGroupResource
        └── PlaywrightWorkspaceResource
            └── PlaywrightWorkspaceQuotaResource (workspace-level quotas)
```

## Core Workflow

### 1. Create Playwright Workspace

```csharp
using Azure.ResourceManager.Playwright;
using Azure.ResourceManager.Playwright.Models;

// Get resource group
var resourceGroup = await subscription
    .GetResourceGroupAsync("my-resource-group");

// Define workspace
var workspaceData = new PlaywrightWorkspaceData(AzureLocation.WestUS3)
{
    // Optional: Configure regional affinity and local auth
    RegionalAffinity = PlaywrightRegionalAffinity.Enabled,
    LocalAuth = PlaywrightLocalAuth.Enabled,
    Tags =
    {
        ["Team"] = "Dev Exp",
        ["Environment"] = "Production"
    }
};

// Create workspace (long-running operation)
var workspaceCollection = resourceGroup.Value.GetPlaywrightWorkspaces();
var operation = await workspaceCollection.CreateOrUpdateAsync(
    WaitUntil.Completed,
    "my-playwright-workspace",
    workspaceData);

PlaywrightWorkspaceResource workspace = operation.Value;

// Get the data plane URI for running tests
Console.WriteLine($"Data Plane URI: {workspace.Data.DataplaneUri}");
Console.WriteLine($"Workspace ID: {workspace.Data.WorkspaceId}");
```

### 2. Get Existing Workspace

```csharp
// Get by name
var workspace = await workspaceCollection.GetAsync("my-playwright-workspace");

// Or check if exists first
bool exists = await workspaceCollection.ExistsAsync("my-playwright-workspace");
if (exists)
{
    var existingWorkspace = await workspaceCollection.GetAsync("my-playwright-workspace");
    Console.WriteLine($"Workspace found: {existingWorkspace.Value.Data.Name}");
}
```

### 3. List Workspaces

```csharp
// List in resource group
await foreach (var workspace in workspaceCollection.GetAllAsync())
{
    Console.WriteLine($"Workspace: {workspace.Data.Name}");
    Console.WriteLine($"  Location: {workspace.Data.Location}");
    Console.WriteLine($"  State: {workspace.Data.ProvisioningState}");
    Console.WriteLine($"  Data Plane URI: {workspace.Data.DataplaneUri}");
}

// List across subscription
await foreach (var workspace in subscription.GetPlaywrightWorkspacesAsync())
{
    Console.WriteLine($"Workspace: {workspace.Data.Name}");
}
```

### 4. Update Workspace

```csharp
var patch = new PlaywrightWorkspacePatch
{
    Tags =
    {
        ["Team"] = "Dev Exp",
        ["Environment"] = "Staging",
        ["UpdatedAt"] = DateTime.UtcNow.ToString("o")
    }
};

var updatedWorkspace = await workspace.Value.UpdateAsync(patch);
```

### 5. Check Name Availability

```csharp
using Azure.ResourceManager.Playwright.Models;

var checkRequest = new PlaywrightCheckNameAvailabilityContent
{
    Name = "my-new-workspace",
    ResourceType = "Microsoft.LoadTestService/playwrightWorkspaces"
};

var result = await subscription.CheckPlaywrightNameAvailabilityAsync(checkRequest);

if (result.Value.IsNameAvailable == true)
{
    Console.WriteLine("Name is available!");
}
else
{
    Console.WriteLine($"Name unavailable: {result.Value.Message}");
    Console.WriteLine($"Reason: {result.Value.Reason}");
}
```

### 6. Get Quota Information

```csharp
// Subscription-level quotas
await foreach (var quota in subscription.GetPlaywrightQuotasAsync(AzureLocation.WestUS3))
{
    Console.WriteLine($"Quota: {quota.Data.Name}");
    Console.WriteLine($"  Limit: {quota.Data.Limit}");
    Console.WriteLine($"  Used: {quota.Data.Used}");
}

// Workspace-level quotas
var workspaceQuotas = workspace.Value.GetAllPlaywrightWorkspaceQuota();
await foreach (var quota in workspaceQuotas.GetAllAsync())
{
    Console.WriteLine($"Workspace Quota: {quota.Data.Name}");
}
```

### 7. Delete Workspace

```csharp
// Delete (long-running operation)
await workspace.Value.DeleteAsync(WaitUntil.Completed);
```

## Key Types Reference

| Type | Purpose |
|------|---------|
| `ArmClient` | Entry point for all ARM operations |
| `PlaywrightWorkspaceResource` | Represents a Playwright Testing workspace |
| `PlaywrightWorkspaceCollection` | Collection for workspace CRUD |
| `PlaywrightWorkspaceData` | Workspace creation/response payload |
| `PlaywrightWorkspacePatch` | Workspace update payload |
| `PlaywrightQuotaResource` | Subscription-level quota information |
| `PlaywrightWorkspaceQuotaResource` | Workspace-level quota information |
| `PlaywrightExtensions` | Extension methods for ARM resources |
| `PlaywrightCheckNameAvailabilityContent` | Name availability check request |

## Workspace Properties

| Property | Description |
|----------|-------------|
| `DataplaneUri` | URI for running tests (e.g., `https://api.dataplane.{guid}.domain.com`) |
| `WorkspaceId` | Unique workspace identifier (GUID) |
| `RegionalAffinity` | Enable/disable regional affinity for test execution |
| `LocalAuth` | Enable/disable local authentication (access tokens) |
| `ProvisioningState` | Current provisioning state (Succeeded, Failed, etc.) |

## Best Practices

1. **Use `WaitUntil.Completed`** for operations that must finish before proceeding
2. **Use `WaitUntil.Started`** when you want to poll manually or run operations in parallel
3. **Always use `DefaultAzureCredential`** — never hardcode keys
4. **Handle `RequestFailedException`** for ARM API errors
5. **Use `CreateOrUpdateAsync`** for idempotent operations
6. **Navigate hierarchy** via `Get*` methods (e.g., `resourceGroup.GetPlaywrightWorkspaces()`)
7. **Store the DataplaneUri** after workspace creation for test execution configuration

## Error Handling

```csharp
using Azure;

try
{
    var operation = await workspaceCollection.CreateOrUpdateAsync(
        WaitUntil.Completed, workspaceName, workspaceData);
}
catch (RequestFailedException ex) when (ex.Status == 409)
{
    Console.WriteLine("Workspace already exists");
}
catch (RequestFailedException ex) when (ex.Status == 400)
{
    Console.WriteLine($"Bad request: {ex.Message}");
}
catch (RequestFailedException ex)
{
    Console.WriteLine($"ARM Error: {ex.Status} - {ex.ErrorCode}: {ex.Message}");
}
```

## Integration with Test Execution

After creating a workspace, use the `DataplaneUri` to configure your Playwright tests:

```csharp
// 1. Create workspace (this SDK)
var workspace = await workspaceCollection.CreateOrUpdateAsync(
    WaitUntil.Completed, "my-workspace", workspaceData);

// 2. Get the service URL
var serviceUrl = workspace.Value.Data.DataplaneUri;

// 3. Set environment variable for test execution
Environment.SetEnvironmentVariable("PLAYWRIGHT_SERVICE_URL", serviceUrl.ToString());

// 4. Run tests using Azure.Developer.MicrosoftPlaywrightTesting.NUnit
// (separate package for test execution)
```
