Create a unit test for construct

@Sinnbeck I tried this for that trow an exception if not valid

public function testConstruct(){

        $sftp = \Mockery::mock(SFTP::class)->makePartial();
        $key = '-----BEGIN RSA PRIVATE KEY-----

        \Config::set('sftp.private_key', base64_encode($key));
        \Config::set('sftp.username', 'sftp-user');

        $this->service->shouldReceive('loadPrivateKey')->withNoArgs()->andReturn('key');

        $this->service->shouldReceive('sftpLogin')->andThrow(\Exception::class);
}

@wipflash what is $this->service? I assume it's a mock set somewhere else?

And are you just trying to mock all classes? So no actual classes are getting called?

@Sinnbeck I am sorry I forgot to add this part.

protected SftpService $service;

    protected function setUp(): void
    {
        $this->service = \Mockery::mock(SftpService::class)
            ->makePartial()
            ->shouldAllowMockingProtectedMethods();

        parent::setUp();
    }

@wipflash Ok so what are you planning on testing if you just mock everything ? I only see mocks, no actual tests. In this case I would assume that the service is real..

@Sinnbeck I am completely new to this and have no idea where or what to start. Here is a complete class on what I want to write tests.
