AWS Laravel Facade Mockery loses __call() method

I'm doing some unit testing on a project that uses the AWS Laravel SDK.

I'm trying to use Mockery with the Aws facade, and it works fine for the first test, then fails for all other tests:

public function testCreateS3Adaptor() {
    \Aws::shouldReceive('createClient')->with('s3', $this->s3config)->andReturn(new S3Client());
    // ... some tests
}

public function testPutFile() {
    \Aws::shouldReceive('createClient')->with('s3', $this->s3config)->andReturn(new S3Client());
    // ... some tests
}

public function testFetchFile() {
    \Aws::shouldReceive('createClient')->with('s3', $this->s3config)->andReturn(new S3Client());
    // ... some tests
}

public function testDeleteFile() {
    \Aws::shouldReceive('createClient')->with('s3', $this->s3config)->andReturn(new S3Client());
    // ... some tests
}

When running the tests:

.EEE

Time: 1.11 seconds, Memory: 31.25Mb

There were 3 errors:

1) S3AdaptorTest::testPutFile
BadMethodCallException: Unknown method: shouldRecieve.

/var/www/vhosts/laravel/storage-handler/tests/S3AdaptorTest.php:63

Now my best guess here is that (somehow) the __call method in the AWS SDK (i.e. the thing that the Facade wraps) is overwriting the __call method in the Facade.

This is the __call method in the AWS SDK:

public function __call($name, array $args)
{
    if (strpos($name, 'create') === 0) {
        return $this->createClient(
            substr($name, 6),
            isset($args[0]) ? $args[0] : []
        );
    }
    throw new \BadMethodCallException("Unknown method: {$name}.");
}

Is there any way to get around this without having to rewrite parts of mockery or the AWS Laravel library?
