ConstDispatches to a registered handler, and rejects for an unknown id.
setContext is the exception, and the only one. It is a VS Code built-in
that no extension registers, so rejecting it would be the mock lying
about the platform — and an extension mirroring a setting into a when
clause is a common enough shape that every one of them would have to work
around it. Other built-ins are left rejecting on purpose: they have
effects a mock cannot stand in for, and silently resolving undefined
would hide a test that never did what it claimed. The call is still
recorded, so mock.calls is how a test asserts the key was published.
Stable configuration target values; persistence is not emulated.
Stable language-status severities for adapter translation tests.
Numeric values needed by log-channel code; no filtering is performed.
Stable ProgressLocation values used to assert adapter mapping.
Quick-input button locations; rendering is outside the mock's scope.
Shared back-button identity used by quick-input navigation tests.
Quick-pick item kinds used in structural item fixtures.
Stable status-bar alignment values used by item factories.
Reveal modes for call-shape assertions; there is no viewport to reveal.
Stable checkbox values used by synthetic tree events.
Stable tree collapsibility values; no tree is rendered.
Host UI kind read by runtime preflight; no host is actually launched.
A plausible vscode.version baseline, pinned by the mock's tests. It is
fixture data—not a claim about the editor running the test. Assign the
exact version a scenario requires instead of branching on this default.
Editor-column values accepted by panel/editor call-shape tests. Columns have no layout behavior in this mock.
Dark by default. A plain mutable field, so a test can assign it
directly — use _setColorTheme instead when listeners registered
through onDidChangeActiveColorTheme also need to fire.
Returns a fresh createMockTextEditor fixture. When document
looks like a mock TextDocument (has getText), it's threaded through
so result.document is the same object the caller passed in, matching
the real API's identity guarantee.
Test hook: switches the active theme and notifies
onDidChangeActiveColorTheme listeners, as VS Code does when the user
picks a different theme.
Used by applyWorkspaceEdits/applyEditsGrouped (src/workspace/editor.ts).
Simplified: returns pathOrUri itself for a string, or .fsPath for a Uri.
Honors { language, content } options; otherwise an empty plaintext document.
Theme-kind values plus a scriptable active-theme namespace.
