NoMatchingExpectationException even with $this->anything() - laravel-4

Question

I'm writing a unit test for a Laravel controller method, but I keep getting NoMatchingExpectationExceptions no matter what I do with the ->with(...). The code under test:
public function destroy($id) {
$foo = FooService::foo($id); //returns a Foo object (an Eloquent model)
$fooCollection = new Collection(array($foo));
$response = FooService::archive($fooCollection);
return Response::json($response);
}
The unit test:
public function testArchiveSingle() {
$foo = Mockery::mock('Foo', array('id' => 1));
$fooCollection = new \Illuminate\Database\Eloquent\Collection();
$fooCollection->add($foo);
FooService::shouldReceive('foo')->once()
->with(1)
->andReturn($foo);
//here's the shouldReceive that's throwing the error:
FooService::shouldReceive('archive')->once()
->with($this->anything())
->andReturn(array('result'=>'here'));
$response = $this->action('DELETE', 'FoosController#destroy',
array('site' => 12345, 'foos' => 1),
array());
$this->assertResponseOk();
$this->assertTrue($response->headers->contains('Content-Type', 'application/json'));
//other tests that are proprietary in nature go here
}
In the ->with() I've tried passing in $fooCollection, $this->instanceOf('Collection'), $this->instanceOf('\Illuminate\Database\Eloquent\Collection') and a few other things. I've also tried changing the $fooCollection definition to just new Collection.
When I run the tests, I get:
Mockery\Exception\NoMatchingExpectationException : No matching handler found for Mockery_1_FooService::archive(Illuminate\Database\Eloquent\Collection). Either the method was unexpected or its arguments matched no expected argument list for this method
When I remove the ->with(...) in the troublesome shouldReceive the test runs fine, but loses value since it wouldn't catch a (theoretical) bug that would accidentally archive too much.

You should use Mockery::any() to match for any argument. PHPUnit's own mock library uses $this->anything(). See the manual.
FooService::shouldReceive('archive')->once()
->with(Mockery::any())
->andReturn(array('result'=>'here'));
