dcli.testing

Headless test harness for the dcli inline terminal-rendering library.

dcli.testing lets you drive the real dcli render engine — input parser, fixed-region composer, scrollback model, overlays, virtual clock — against in-memory fakes instead of a real TTY. No PTY, no raw mode, no ANSI pollution in your test output.

Quick start

using Dcli;
using Dcli.Testing;
using Xunit;

public class MyFeatureTests
{
    [Fact]
    public async Task StatusLineAppearsInSnapshot()
    {
        await using HeadlessTerminal harness = await HeadlessTerminal.StartAsync();

        harness.Terminal.Status.SetRows([new Line([new Segment("Ready")])]);
        await harness.SettleAsync();

        FrameSnapshot snap = harness.Snapshot;
        string pretty = FrameSnapshotPrinter.PrettyPrint(snap);

        Assert.Contains("Ready", pretty);
    }
}

Key types

Type	Description
`HeadlessTerminal`	Entry point. `StartAsync()` builds a live harness; `SettleAsync()` drains pending work and waits for a coalesced frame.
`HeadlessTerminalOptions`	Configures initial size, minimum frame interval, and virtual clock.
`VirtualClock`	Deterministic clock; `Advance(span)` advances time without wall-clock delay, triggering throttled paints.
`FrameSnapshot`	Immutable capture of `LiveWindowRows`, `FixedRegionRows`, caret, size, newly-committed rows, and overlay state.
`FrameSnapshotPrinter`	`PrettyPrint(snapshot)` — ASCII-bordered, style-stripped frame string, stable for golden-frame assertions.

Scripting methods

Method	What it does
`SendKey(KeyEvent)`	Injects a named or character key directly into the render loop.
`Type(string)`	Types each rune as a `Char` key event. For named keys (Enter, Tab, arrows) use `SendKey`.
`Paste(string)`	Posts a bracketed-paste event.
`Feed(ReadOnlySpan<byte>)`	Feeds raw bytes through the real VT parser on the InputReader thread.
`Resize(cols, rows)`	Triggers a resize event via the same path as POSIX SIGWINCH.

What's NOT here

This package contains only the headless harness. The production dcli rendering engine, public API (ITerminal, Scrollback, Input, Status, Autocomplete), and event model live in the dcli package. Add both packages to test projects:

<PackageReference Include="dcli" Version="0.1.0-rc.1" />
<PackageReference Include="dcli.testing" Version="0.1.0-rc.1" />
