在测试中模拟存储获取器时出现问题（我使用vuenit）。我要编写一个代码，该代码可通过模拟存储（模拟状态和吸气剂）安装组件：
let vm
let $store
let mount
beforeEach(function(){
$store=mockStore({
requests: {
state: {
all: 9001,
serviceManagerRequests:228
},
getters: {
getServiceManagerRequestsCount: function(){
return jest.fn().mockImplementation(function(){
return 228
})
},
getAllRequestsCount: function(){
return jest.fn().mockImplementation(function(){
return 9001
})
},
isServiceManager: function(){
return jest.fn().mockImplementation(function(){
return true
})
}
}
},
})
mount=build(AccountSideMenu, {
inject:$store,
router:true
})
vm=mount()
});
AccountSideMenu是一个组件，它使用Vuex存储。 吸气剂在商店代码中定义：
getServiceManagerRequests: state => () => state.serviceManagerRequests,
getServiceManagerRequestsCount: state => () =>state.serviceManagerRequests.length
在组件上，我有吸气剂，在Nuxt模板中定义（有其中之一的示例）。如您所见，它直接在模板上使用getter：
<ul class="uk-nav uk-nav-default" uk-nav >
<!-- v-if="isServiceManager" -->
<li class="uk-nav-header">Management menu</li>
<li><nuxt-link to="/account/requests-manager"><span uk-icon="icon: list" class="uk-margin-small-right uk-icon"></span>Customer requests <span class="uk-badge">{{getServiceManagerRequestsCount()}}</span></nuxt-link></li>
<li class="uk-nav-divider"></li>
</ul>
运行测试代码时，我得到：

如何模拟吸气剂以将其显示在组件上（如何将吸气剂直接注入组件中？）？
