Krumb.MockingToolbox

A web dashboard for mocking outgoing HTTP calls from typed HttpClients in ASP.NET Core apps during testing.

Point it at any app using IHttpClientFactory and it automatically discovers every outgoing call, lets testers mock specific endpoints (with per-id targeting, scenarios, and a global kill switch) from a web dashboard, and requires zero code changes to the calling code itself.

Features

  • Zero-touch discovery - a global IHttpMessageHandlerBuilderFilter auto-wires every registered HttpClient. No attributes, no per-client opt-in required.
  • Per-endpoint, per-id mocking - mock GET /orders/{id} for every id, or just id 123, independently.
  • Scenarios - bundle multiple mocks into a named preset ("Payment provider down"). Activating one snapshots and restores every other mock's state automatically.
  • Global kill switch - disable all mocking instantly from the dashboard, without a redeploy, and it survives an app restart.
  • Staleness tracking - endpoints not seen in a configurable window get flagged, so stale mocks don't silently rot.

Install

This package alone only gives you the dashboard and discovery engine - you also need a storage provider:

Quick start (with PostgreSQL storage)

services.AddMockingToolbox(options =>
{
    options.IsEnabled = environment.IsDevelopment() || environment.IsStaging();
    options.DashboardPath = "/mocking";
    options.UsePostgreSql(connectionString);
});

app.UseMockingToolbox();

That's it. Every AddHttpClient<...>() registration in the app is wired automatically. Open /mocking to see every discovered endpoint and start mocking.
