Question

I’m writing some unit tests for a class loader, and the first test is there to assert that trying to reference a class without loading it first will indeed fail.

The test looks like this:

/**
 * @expectedException PHPUnit_Framework_Error
 */
public function testInstantiateUnloadedClass() {
    $foo = new Foo();
}

Sadly, running the test yields this message:

PHP Fatal error: Class ‘Foo’ not found in /Users/jfvaren/workspace/classloader/ClassLoaderTest.php on line 7

Must I simply accept that this is not doable?

Answer 1

Call class_exists(), this tries to autoload the class and returns boolean false if it isn’t able to.
