/**
|
||||
* report-designer-vue 组件测试。
|
||||
*
|
||||
* 验证：
|
||||
* - 主布局挂载后渲染三栏结构（工具栏/工具箱/属性面板/状态栏/画布）。
|
||||
* - 工具箱可新增元素并反映到画布。
|
||||
* - 点击画布元素可选中，属性面板显示其信息；点击空白取消选中。
|
||||
* - 工具栏撤销可用。
|
||||
* - 画布缩放、页面尺寸、标尺刻度。
|
||||
* - 拖拽移动元素，且连续拖拽合并为一步撤销。
|
||||
* - 快捷键（Delete / Ctrl+Z），输入态下不触发。
|
||||
* - 主题样式注入是幂等的。
