Vue Test Utils - Skip created hook

问题

I want to skip all of the methods that are being called within the created() hook. Is there a way to do this?

So instead of this

        created() {
            this.getAllocations();
            this.getModels();
            this.getTeams();
            this.getCustodians();
            this.getDefaultFeeStructure();
        }

I want this

created() { }

It's worth noting, I cannot actually change the component itself, but for testing purposes, this needs to be done.

You can accomplish this with a global mixin (see https://vuejs.org/v2/guide/mixins.html#Global-Mixin)

However, for your case you need a custom merge strategy to prevent the created hook on the component from being run:

Hook functions with the same name are merged into an array so that all of them will be called. Mixin hooks will be called before the component’s own hooks. (https://vuejs.org/v2/guide/mixins.html#Option-Merging)

See a working example at https://jsfiddle.net/rushimusmaximus/9akf641z/3/

Vue.mixin({
  created() {
    console.log("created() in global mixin")
  }
});

const mergeCreatedStrategy = Vue.config.optionMergeStrategies.created;
Vue.config.optionMergeStrategies.created = (parent, child) => {
  return mergeCreatedStrategy(parent);
};

new Vue ({
  el: "#vue-app",
  template: '<p>See console output for logging. Rendered at {{renderDate}}</p>',
  data() {
    return {
     renderDate: new Date()
    }
  },
  created() {
    console.log("created() in component")
  }
})
