facing an obstacle in Fixtures creation in the Simpletest

Question

I am beginner to Simpletest and facing an issue while creating fixtures. As I am using cakephp 1.3.14 version for my application.

1. Created fixture with filename complaint_fixture.php

   class ComplaintFixture extends CakeTestFixture {
   
       var $name = 'Complaint';
       var $import = array('table' => 'complaints', 'records' => true);
   
       // do not truncate movie_stars table between tests
       public function truncate($db) {
           return null;
       }
   
       // do not drop movie_stars table between tests
       public function drop($db) {
           return null;
       }
   
   }
   

2. Created test case with name complaint.test.php

   App::import('Model', 'Complaint');
   
   class ComplaintTestCase extends CakeTestCase {
   
       var $fixtures = array('app.Complaint');
   
       function setUp($method) {
           parent::setUp();
           $this->Complaint = & ClassRegistry::init('Complaint');
   
           // load data
           $this->loadFixtures('Complaint');
       }
   
       function testFixture() {
           $numberOfResults = $this->Complaint->find('count');
           var_dump($numberOfResults);
       }
   
       /*
         function testupdateComplaintStatus(){
         $result = $this->Complaint->updateComplaintStatus(47,'ACT');
         $this->assertEqual($result,1,'Status updated successfully!');
         } */
   }
   

As you can see in the above code, a fixture is created with name Complaint and then a test case is being used to load that fixture. So, what I have read on it from developer guide - we do create a fixture with specifying the fields name and a records set - load that fixture in test model class.

BUT, what I am looking for is to perform CRUD operations on test data which is being inserted into the test database. And, when I try to do the same with above given script, It starts affecting the production database records instead of test database.

If you see in the above code I have even stopped truncate and drop for test data, yet not able to sort out the issue.

Can anyone let me know what I have missed in the above code?
