WebViewDriver.Host

This is the app-side package for WebViewDriver. It exposes an embedded webview to tests through a local JavaScript evaluation endpoint.

Install this package in the app under test. Install WebViewDriver.Selenium in the test project.

Setup

using Microsoft.Maui.Handlers;
using WebViewDriver.Host;

#if DEBUG
WebViewDriverHost.TryStartFromEnvironment();

HybridWebViewHandler.Mapper.AppendToMapping("WebViewDriver", (handler, _) =>
{
#if MACCATALYST || IOS
    WebViewDriverHost.Attach(
        "main",
        (WebKit.WKWebView)handler.PlatformView);
#endif
});
#endif

Custom webview wrappers can provide an evaluation delegate:

WebViewDriverHost.Attach(
    "main",
    script => myWebView.EvaluateJavaScriptAsync(script));

The test launcher must set both environment variables:

WEBVIEWDRIVER_PORT=17321
WEBVIEWDRIVER_TOKEN=<random per-run token>

The host remains inactive when either value is missing.

Readiness

An app can prevent clients from connecting before startup is complete:

WebViewDriverHost.SetReady("main", false);
// Finish application startup.
WebViewDriverHost.SetReady("main", true);

Security

This package provides JavaScript evaluation inside the app. Include and register it only in Debug or QA builds.

The endpoint listens on 127.0.0.1 only.
Every request requires the session token.
Requests are size-limited.
Evaluations are serialized per webview.
No shell, file-system, or reflection API is exposed.

See the project documentation for the complete setup and supported commands.
