Since CakePHP discourages from importing models directly into components we need a controller to access the data in the model.

If the startup() function of the component looks like this:

public function startup(&$controller){ 
          $this->Transporter = $controller->Transporter;  
 }

1. public function startup(&$controller){
2. $this->Transporter = $controller->Transporter;
3. }

then we can just design a really simple fake class:

class FakeTransporterController {} 

1. class FakeTransporterController {}

and assign values into it like this:

$this->TransporterComponentTest = new TransporterComponent(); 
$controller = new FakeTransporterController(); 
$controller->Transporter = new TransporterTest(); 
$this->TransporterComponentTest->startup(&$controller); 

1. $this->TransporterComponentTest = new TransporterComponent();
2. $controller = new FakeTransporterController();
3. $controller->Transporter = new TransporterTest();
4. $this->TransporterComponentTest->startup(&$controller);

Just create a class that extends CakeTestCase and start writing tests!

class TransporterTestCase extends CakeTestCase {
    var $fixtures = array('transporter');  
    function testGetTransporter() { 
          $this->TransporterComponentTest = new TransporterComponent(); 
          $controller = new FakeTransporterController(); 
          $controller->Transporter = new TransporterTest(); 
          $this->TransporterComponentTest->startup(&$controller); 
   
          $result = $this->TransporterComponentTest->getTransporter("12345", "Sweden", "54321", "Sweden"); 
          $this->assertEqual($result, 1, "SP is best for 1xxxx-5xxxx"); 
           
          $result = $this->TransporterComponentTest->getTransporter("41234", "Sweden", "44321", "Sweden"); 
          $this->assertEqual($result, 2, "WSTS is best for 41xxx-44xxx"); 
   
          $result = $this->TransporterComponentTest->getTransporter("41001", "Sweden", "41870", "Sweden"); 
          $this->assertEqual($result, 3, "GL is best for 410xx-419xx"); 
   
          $result = $this->TransporterComponentTest->getTransporter("12345", "Sweden", "54321", "Norway"); 
          $this->assertEqual($result, 0, "Noone can service Norway");         
   }
}
 

1. class TransporterTestCase extends CakeTestCase {
2. var $fixtures = array('transporter');
3. function testGetTransporter() {
4. $this->TransporterComponentTest = new TransporterComponent();
5. $controller = new FakeTransporterController();
6. $controller->Transporter = new TransporterTest();
7. $this->TransporterComponentTest->startup(&$controller);
9. $result = $this->TransporterComponentTest->getTransporter("12345", "Sweden", "54321", "Sweden");
10. $this->assertEqual($result, 1, "SP is best for 1xxxx-5xxxx");
12. $result = $this->TransporterComponentTest->getTransporter("41234", "Sweden", "44321", "Sweden");
13. $this->assertEqual($result, 2, "WSTS is best for 41xxx-44xxx");
15. $result = $this->TransporterComponentTest->getTransporter("41001", "Sweden", "41870", "Sweden");
16. $this->assertEqual($result, 3, "GL is best for 410xx-419xx");
18. $result = $this->TransporterComponentTest->getTransporter("12345", "Sweden", "54321", "Norway");
19. $this->assertEqual($result, 0, "Noone can service Norway");
20. }
21. }
