Testing VueJS component containing other components written by myself

seems to work fine I work on a website with multiple components that contain other components. Now I would like to test if the save button of a form is deactivated correctly if no data is set. I am using vuetify for the UI and Jest for testing. , instead of mount, use shallowMount.

Is vuejs component's style global to other components

With these it helps Styles defined in the style tag of a Vue single-file-component will be compiled to a singular file, affecting all components.
But, you can specify a scoped attribute on the component's style tag:
code :
<style scoped>
  .row {
    background-color: red;
  }
</style>
How to trigger event in all sibling components except current component in vuejs?

this one helps. Why not pass the current component as an event argument and use that to check if the event originated from this component or another one.
code :
edit() {
  this.editing = true;
  EventBus.$emit('editing-another-field', this);
}

created() {
  EventBus.$on('editing-another-field', source => {
    if (source !== this) {
      this.editing = false;
    }
  });
}
edit() {
  EventBus.$emit('editing-field', this);
}

created() {
  this.editingFieldHandler = vm => {
    this.editing = vm === this;
  };

  EventBus.$on('editing-field', this.editingFieldHandler);
}

destroyed() {
  EventBus.$off('editing-field', this.editingFieldHandler);
}
VueJs: Pass Dynamic Components as props to another Component and render them

Hope this helps As suggested in the comments above, you can use a dynamic component in your template and pass the definition of the component in your property.
code :
console.clear()

const ColumnOne = {
  template: `<h1>I am ColumnOne</h1>`
}

const ColumnTwo = {
  template: `<h1>I am ColumnTwo</h1>`
}

Vue.component("parent-comp",{
  props:["columns"],
  template:`
    <div>
      <component v-for="column in columns" 
                 :is="column.customComponent" 
                 :key="column">
      </component>
    </div>
  `
})

new Vue({
  el:"#app",
  data:{
    columns:[{
      name: "something",
      customComponent: ColumnOne
    }, {
      name: "another thing",
      customComponent: ColumnTwo
    }]
  }
})
<script src="https://unpkg.com/vue@2.2.6/dist/vue.js"></script>
<div id="app">
  <parent-comp :columns="columns"></parent-comp>
</div>

hop of those help? Let us assume we have 100 components. We usually add the component selector/name in HTML tags to the template of the parent component.But here we have 100's of components, so is there any dynamic way to add them?? , There is a Vue tag:
code :
<component :is="myComponent"></component>

I hope this helps you . Summary - typical reasons for using components:
Maintainability. Rendering performance via component boundaries. Loading performance via chunking.
code :
<select-box :some-prop="blah">
  <select-box-option v-for="something" />
</select-box>
<nav-sidebar @navigate="onNavigate" />
<div v-for="item in items">...</div>
<div v-for="item in items" :class="getClassesFor(item)">...</div>
<my-component v-for="item in items" :item="item" />
