Summary
How can I create a base class that extends PHPUnit_Framework_TestCase and use that for subclassing actual test cases, without having the base class itself tested by PHPUnit?
Further explanation
I have a series of related test cases for which I have created a base class that contains some common tests to be inherited by all test cases:
BaseClass_TestCase.php:
class BaseClass_TestCase extends PHPUnit_Framework_TestCase {
function test_common() {
// Test that should be run for all derived test cases
}
}
MyTestCase1Test.php:
include 'BaseClass_TestCase.php';
class MyTestCase1 extends BaseClass_TestCase {
function setUp() {
// Setting up
}
function test_this() {
// Test particular to MyTestCase1
}
}
MyTestCase2Test.php:
include 'BaseClass_TestCase.php';
class MyTestCase2 extends BaseClass_TestCase {
function setUp() {
// Setting up
}
function test_this() {
// Test particular to MyTestCase2
}
}
My problem is that when I try to run all the tests in the folder, it fails (without output).
Trying to debug I've found that the problem lies with the base class being itself a subclass of PHPUnit_Framework_TestCase and therefore PHPUnit will also try to run its tests. (Until then I naively thought that only classes defined inside actual test files - filenames ending in Test.php - would be tested.)
Running the base class as a test case out of context doesn't work due to details in my specific implementation.
How can I avoid the base class being tested, and only test the derived classes?
