ContextMenuStrip

A ContextMenuStrip can be verified as follows:

[Test]
public Task ContextMenuStrip()
{
    var menu = new ContextMenuStrip();
    var items = menu.Items;

    items.Add(new ToolStripMenuItem("About"));
    items.Add(new ToolStripMenuItem("Exit"));
    return Verify(menu);
}

^{snippet source | anchor}
