vue-test-utils 1.0.0-beta.11 setData Error

[OneIsAll-L]

First use, encountered setData problem.Ask everyone for help.
my code：
it('setData()方法', () => { const wrapper = mount(Counter) wrapper.setData({foo: 'bar'}) expect(wrapper.vm.foo).to.equal('bar') })
terminal：
setData()方法 Counter.vue AssertionError: expected undefined to equal 'bar' at Context.<anonymous> (webpack:///test/unit/specs/Counter.spec.js:81:30 <- index.js:12255:31)

Hey, this is the repo for avoriaz.

Try updating to @vue/test-utils beta.16:

npm i -D @vue/test-utils
