Please add unit test guide.

Confirmation

• I can confirm this is a feature request for the Vue component instead of ECharts itself.

Details

I'm unit testing vue-echart with version 6.5.4, and my test code as following:

it("should render page", async () => {
    const wrapper =  mount(MyComp, {
      props: {
        name: "name",
        data: [...]
      }
    })
    expect(wrapper).not.to.be.null
    expect(wrapper).contains(VChart).to.be.true
  })

Error occurs running this test case:

[Vue warn]: Component is missing template or render function. 
  at <Anonymous option= {....

More detail:

• Test framework: vitest
• Using <v-chart option=""/> inside MyComp

Could you please provide some helpful tutorial about this?

Testing should be no different from other components. I don't think we have anything special to add.

确实有所不同，mount VChart组件都不能正确被渲染。
还是要考虑一下常见单元测试工具的集成吧，毕竟还是有人会关注的。

Sounds more like a bug with your testing library as it should support mounting any valid Vue component.
