ModernFormsNext.Testing

ModernFormsNext.Testing provides deterministic headless application tests over real framework controls, layout, input routing, focus, commands and rendering. A controlled clock drives the production animation scheduler. Scoped clipboard/lifecycle/settings services keep tests isolated.

using ModernFormsNext;
using ModernFormsNext.Testing;

using var host = ModernFormsTestHost.Create();
var form = new Form { Name = "MainForm" };
var save = form.Controls.Add(new Button { Name = "save", Dock = DockStyle.Bottom, Text = "Save" });

TestWindowHost window = host.Show(form, 400, 300);
window.Input.Click(save);
host.ProcessPendingWork();
ControlTreeSnapshot snapshot = window.CaptureTree();
using RenderedSnapshot rendered = window.CaptureRenderedSnapshot();

Run all host/UI operations and disposal on the creating thread; serialize tests within a process. The host opens no native window and never accesses the OS clipboard. Off-screen snapshots are caller-owned and depend on the actual font/rendering environment. Native IME, Android Activity recreation, OS activation/popup behavior, accessibility and device behavior still require separate integration tests. Navigation/virtualization testing follows their future production contracts.

ShowDialog uses real Form modality and exposes its result task. ActivePopup/Popups provide input and snapshots for real control popups. Native foreground rules are separate from these shared framework checks.

See the TestHost guide for supported input keys, timer/frame semantics, diagnostics, ownership, and examples.
