Difference between assertEquals and assertSame in PHPUnit?

Question

PHPUnit contains an assertEquals() method, but it also has an assertSame() one. At first glance it looks like they do the same thing.

What is the difference between the t

Answer 1

As it's been said before,AssertSame reports an error if the two elements do not share type and value but it's also important to note this from the docummentation:

Reports an error identified by $message if the two variables $expected and $actual do not reference the same object.

So this test would fail too even though they share type and value:

class SameTest extends TestCase
{
    public function testFailure()
    {
        $this->assertSame(new stdClass, new stdClass);
    }
}
