Just Add this data-hasrequired=" Required Fields" data-mage-init='{"validation":{}}' line to your form tag as show in below example and need to set validation class in input element like data-validate='{}'

<form id="test" name="test" method="post"  action="<?php echo $block->getUrl('test/index/test'); ?>" data-hasrequired="* Required Fields"  data-mage-init='{"validation":{}}'>
    <div class="input-box">
         <input name="name" id="name" title="<?php echo __('First name / last name'); ?>" value="" class="input-text required-entry" type="text" data-validate='{"required":true}'>
         </div>
    </form>
