phpunit test method with static methods inside

I want to mock Carbon::now() and Transaction::where... (eloquent model in laravel) with Mockery. Is it possible? I don't have any idea how can I do this when code is written without dependency injection

class SomeClass
{
   public function getLatest()
   {
        $cacheTime = Carbon::now();

        if ($cacheTime > 'xxxx') {
            return 'abcdefgh';
        }

        return Transaction::where('base', '=', 'asas')
            ->where('target', '=', 'bbbb')
            ->orderByDesc('created_at')
            ->first();
   }
}

You can easily mock Carbon:

http://carbon.nesbot.com/docs/#api-testing

$knownDate = Carbon::create(2001, 5, 21, 12);          // create testing date
Carbon::setTestNow($knownDate);                        // set the mock (of course this could be a real mock object)
echo Carbon::now();                                    // 2001-05-21 12:00:00

So in your unit test just call Carbon::setTestNow($knownDate); before your function call. Something like that:

public function testGetLatest()
{
    $knownDate = Carbon::create(2001, 5, 21, 12);          // create testing date
    Carbon::setTestNow($knownDate);  
    $someClass = new SomeClass;

    $result = $someClass->getLatest();

    ...
}

I don't think you can mock Transaction::where in your code and there is no purpose of doing it. The where and orderByDesc functions just setting your query. The first function will actually return the Transaction object. Even if you could mock or stub the first function, then your test is kind of useless because you are testing that your getLatest function returns some kind of mock object created by you.

This is actually a good example of integration test and Laravel provides a variety of helpful tools to make it easier. Check out this link:
