Hi I have a component that gets the prop "access" and a computed property into a setter when access changes I call this.$emit('update:access', val) which updates the property in the parent via :access.sync="access". The problem is that my tests break when it needs to change this property.

If I use wrapper.setData({ accessComputed: 2 }) nothing updated If I use wrapper.setData({ access: 2 }) I have error with mutation props Maybe it's related to .sync? I will be grateful for any help

child component

  props:{
        access:{
          type: Number,
          required: true
        },
      },
      computed:{
        accessComputed:{
          get() {
            return this.access
          },
          set(val) {
            this.$emit('update:access', val)
          }
        },
      },
methods:{
    changeTypeAccess(){
      this.$nextTick(() => {
        switch (this.accessComputed){
          case 2:
            this.generatePassword()
            break;
          case 3:
            this.generateLink()
            break;
        }
      });
    }
}

parent

 <AccessType
             :access.sync="access"
          />
