change selected option of v-select using vue-test-util

I'm trying to test a component builded with vuetify. For that I'm using vue-test-utils. My goal is to perform a change in the v-select field, and assert hat a mutation is performed. here is my code:

<div id="app">
  <v-app id="inspire">
    <v-container fluid>
      <v-layout row wrap>
        <v-flex xs6>
          <v-subheader>Standard</v-subheader>
        </v-flex>
        <v-flex xs6>
          <v-select
            :items="items"
            v-model="e1"
            label="Select"
            single-line
          ></v-select>
        </v-flex>
      </v-layout>
    </v-container>
  </v-app>
</div>

The first test is ok when i set the data:

componentWrapper.setData({items: storesList})
expect(componentWrapper.vm.$data.items).toHaveLength(2)

I now want to change the selected value I try: 

componentWrapper.findAll('#option').at(1).setSelected()

And also

componentWrapper.find('el-select')

Can someone help me to retrieve the select and then change the selected value? Thanks for your support.

My solution. It's very equivalent to YounSeon Ahn's response, just the options selector changed. I'm using Vuetify 2.2.11.

// Found the v-select
wrapper.find('[data-testid="mySelect"]').trigger('click'); 
// Wait for DOM updating after the click
await localVue.nextTick();
// Find all options and select the first. If you are multiple v-select in your form, the class ".menuable__content__active" represents the current opened menu
wrapper.find('.menuable__content__active').findAll('.v-list-item').at(0).trigger('click');

finally got this working for vuetify 1.5. If your v-select looks like this:

 <v-select      
        :items="projectManagers"
        :value="selectedProjectManager"
        key="UserId"
        label="Choose Name"
        item-text="FirstName"
        item-value="UserId"        
        id="nameSelect"
        @input="(val)=>{this.handleNameChange(val)}"
 />

then do this:

wrapper.findAll('#nameSelect').at(0).trigger('input')

this works, but for some reason if i do at(1) it does not work. Thankfully for my test case the option at position 0 is fine

Use wrapper.vm.selectItem('foo'). It works for me.

I found this in vuetify v-select tests:

Old: ~~https://github.com/vuetifyjs/vuetify/blob/master/packages/vuetify/test/unit/components/VSelect/VSelect.spec.js#L533~~

New: https://github.com/vuetifyjs/vuetify/blob/b2abe9fa274feeb0c5033bf12cc48276d4ac5a78/packages/vuetify/test/unit/components/VSelect/VSelect.spec.js#L28

This is my final solution to test Vuetify VSelect component in cypressjs:

  cy.get('#YourVSelectComponentId', { timeout: 20000 }).should('not.have.attr', 'disabled', 'disabled').click({ force: true }); //find v-select, verify it's visible and then click.

  cy.get('.menuable__content__active').first().find('.v-list__tile').first().should('be.visible').click(); //find opened dropdown, then find first item in options, then click

wrapper.findAll('.v-list__tile__title').at(0).trigger('click')

It works for me. By this code, first option is selected.

Here is ref.

I used Vuetify v1.5.5.

I have been struggling with this as well and finally found a way to do it. I'm using Jest and vue-test-utils. Basically, you have to do it with two separate steps. Mark the option as selected and then trigger the change on the select.

The HTML part is:

      <select id="groupid" v-model="groupID">
        <option value="">-Select group-</option>
        <option v-for="g in groupList" 
          v-bind:value="g.groupId">{{g.groupId}} - {{g.groupName}}
        </option>
      </select>

And the test is:

it('should populate the subgroup list when a group is selected', () => {
  expect(cmp.vm.groupID).toBe('');
  expect(cmp.findAll('select#groupid > option').length).toBe(3);
  cmp.findAll('select#groupid > option').at(1).element.selected = true;
  cmp.find('select#groupid').trigger('change');
  expect(cmp.vm.groupID).not.toBe('');
});
