Models tests

What is expected:

• Create tests for models;

Hi @mansogf, I'd like to implement the model tests.

I'll use this approach:

def test_error_model_cpu():
    with pytest.raises(Exception) as TypeError:
        cpu = Cpu(non_existent_field="Test")

def test_model_cpu():
    cpu = Cpu(
        id=1, name="Cpu name test", number_of_cores=2, frequency=3.456,
        fp32_per_cycle=7, transistors=8, tdp=9.101, gflops=1.121, die_size=3, year=2014
    )

    assert "app.models.cpu" == cpu.__module__    
    assert "cpu" == cpu.__tablename__

    assert 1 == cpu.id
    assert "Cpu name test" == cpu.name
    assert 2 == cpu.number_of_cores
    assert 3.456 == cpu.frequency
    assert 7 == cpu.fp32_per_cycle
    assert 8 == cpu.transistors
    assert 9.101 == cpu.tdp
    assert 1.121 == cpu.gflops
    assert 3 == cpu.die_size
    assert 2014 == cpu.year

Can I start?
