Return value

A promise that’s resolved to a RenderedTestMessageDialog instance for checking content or pressing buttons, or rejected when a timeout occurs.

describe("My scope", () => {
  test("Cancel confirm dialog", async (t) => {
    // ...
    let p = app.showConfirmDialog("Are you sure?");
    await (
      await t.expectMessageDialogAsync(100, /sure/)
    ).cancelAsync();
    let result = await p;
