Acceptance Test Authoring (Playwright)

Acceptance Test Authoring (Playwright)

This skill covers writing end-to-end acceptance tests using Playwright (.NET) to verify migrated Blazor applications work correctly.

Architecture

Test Suites

Shared Infrastructure

Every test suite uses the same pattern:

PlaywrightFixture.cs — Shared browser instance:

public class PlaywrightFixture : IAsyncLifetime
{
    public IPlaywright Playwright { get; private set; } = null!;
    public IBrowser Browser { get; private set; } = null!;

    public async Task InitializeAsync()
    {
        Playwright = await Microsoft.Playwright.Playwright.CreateAsync();
        Browser = await Playwright.Chromium.LaunchAsync(new BrowserTypeLaunchOptions
        {
            Headless = true
        });
    }

    public async Task DisposeAsync()
    {
        await Browser.DisposeAsync();
        Playwright.Dispose();
    }
