How can I test how to manually open an angular material directive for unit testing?
<div layout-gt-xs="row">
<div class="col-md-12">
<md-input-container>
<label class="input-label">{{ 'policyform.DOB' | translate }}</label>
<md-datepicker ng-model="vm.data.dob" name="policyHolderDob"
ng-required="vm.config.dob.required"
md-min-date="vm.minDate"
md-max-date="vm.maxDate"
min-age="{{vm.config.dob.minage}}"
max-age="{{vm.config.dob.maxage}}">
</md-datepicker>
<uex-form-validation form="vm.policyForm" field="policyHolderDob" config="vm.config.dob"></uex-form-validation>
</md-input-container>
</div>
</div>
