Playwright Integration

End-to-end browser testing with Playwright for .NET.

Overview

C# Dev Tools supports Playwright test projects for browser automation testing.

Test Discovery

Playwright tests are discovered automatically:

• Test Explorer recognizes Playwright test projects
• Tests appear alongside unit tests
• Organized by test class and method

Running Playwright Tests

Run browser tests like any other test:

1. Click “Run Test” in Test Explorer
2. Or right-click test project: “Run Tests”
3. Browser launches and executes tests
4. Results appear in Test Explorer

Debugging Playwright Tests

Debug browser interactions:

1. Set breakpoints in test code
2. Click “Debug Test” in Test Explorer
3. Debugger stops at breakpoints
4. Inspect browser state and variables

Creating Playwright Tests

Create test files with templates:

1. Use Quick Add: MyPlaywrightTest.cs
2. Or right-click: Add > New File
3. Template includes Playwright setup

Common Scenarios

Page Navigation

await page.GotoAsync("https://example.com");

Element Interaction

await page.ClickAsync("#submit-button");
await page.FillAsync("#username", "testuser");

Assertions

await Expect(page.Locator("h1")).ToHaveTextAsync("Welcome");

Best Practices

• Use Page Object Model pattern
• Keep tests independent
• Use proper wait strategies
• Clean up browser state between tests
• Configure timeouts appropriately

Configuration

Configure Playwright in test project:

• Browser types (Chromium, Firefox, WebKit)
• Headless vs headed mode
• Screenshots on failure
• Video recording
• Timeout settings

Integration Benefits

• Unified test management
• Combined unit and E2E test results
• Consistent debugging experience
• Single test runner for all tests
