Bug description:Overriding method with an abstract method
Description:
------------
In Java you can override a method with an abstract one, but in PHP it
results in:
Fatal error: Cannot make non abstract method
IdentifiableExceptionTests::getSystemUnderTest() abstract in class
RestResponseExceptionTests in xxx on line yyy
Test script:
---------------
class HttpNotFoundException extends RestResponseException {
public function getHttpStatusCode() {
// ...
}
}
abstract class RestResponseException extends IdentifiableException {
public abstract function getHttpStatusCode();
}
class IdentifiableException extends Exception {
// ...
}
// ----------------------- and here come the tests:
class HttpNotFoundExceptionTests extends RestResponseExceptionTests {
protected function getSystemUnderTest() {
return new HttpNotFoundException();
}
// ... tests logic specific to HttpNotFoundException
}
class RestResponseExceptionTests extends IdentifiableExceptionTests {
/**
* @return RestResponseException
*/
protected abstract function getSystemUnderTest();
// ... tests specific for RestResponseException, even though it is an
abstract class, it has some logic implemented and tests for that portion of
logic are specified here. It is important to note that while
getSystemUnderTest() method in IdentifiableExceptionTests expects
IdentifiableException, in RestResponseExceptionTests it expects
RestResponseException, which is a proper subclass of IdentifiableException
}
class IdentifiableExceptionTests extends PHPUnit_Framework_TestCase {
/**
* @return IdentifiableException
*/
protected function getSystemUnderTest() {
return new IdentifiableException();
}
//... tests IdentifiableException logic
}
Expected result:
----------------
I expect this code to work.
It works in Java, so why cannot it work in PHP?
Actual result:
--------------
Fatal error: Cannot make non abstract method
IdentifiableExceptionTests::getSystemUnderTest() abstract in class
RestResponseExceptionTests in xxx on line yyy
