title: CakePHP 3.x - fixtures import does not load data
body: <p>I am trying to import fixtures in my CakePHP 3.x plugin. 
  When I launch the tests, I always get the error : </p>
  
  <blockquote>
    <p>UserManager\Test\TestCase\Controller\UsersControllerTest::testProfile
    exception 'Cake\Datasource\Exception\RecordNotFoundException' with message 'Record not found in table "users"</p>
  </blockquote>
  
  <p>Here is UsersFixture.php :</p>
  
  <pre><code>namespace UserManager\Test\Fixture;
  use Cake\TestSuite\Fixture\TestFixture;
  
  class UsersFixture extends TestFixture {
      public $import = ['table' =&gt; 'users'];
  }
  </code></pre>
  
  <p>My test fails because it can not find the current user in test database. </p>
  
  <p>I supposed that users table is created successfully, but no data are imported. </p>
  
  <p>Of course, many users are recorded in my existing users table, and the tested user id is one of these records. </p>
  
  <p>My testIndex() method fails too, because number of records is always equal to 0. </p>
  
  <p>Why does the fixtures table not contain my records ?</p>
