The test:
public function testAdd(): void
{
$this->session([
'Auth' => [
'id' => 1,
'DNI_CIF' => '22175395Z',
'name' => 'Prueba',
'lastname' => 'Prueba Prueba',
'username' => 'Pruebatesting',
'password' => 'prueba',
'email' => 'prueba#gmail.com',
'phone' => '639087621',
'role' => 'admin',
'addres_id' => 1
]
]);
$this->get('animal/add');
$this->assertResponseOk();
$data=[
'id' => 1,
'name' => 'AñadirAnimal',
'image' => '',
'specie' => 'dog',
'chip' => 'no',
'sex' => 'intact_male',
'race' => 'cat',
'age' => 1,
'information' => 'Es un animal.',
'state' => 'sick',
'animal_shelter' => [
'id' => 1,
'start_date' => '2022-11-03 10:47:38',
'end_date' => '2022-11-03 10:47:38',
'user_id' => 1,
'animal_id' => 1
]
];
$this->enableCsrfToken();
$this->post('animal/add',$data);
$this->assertResponseOk();
}
The controller:
public function add()
{
$animal = $this->Animal->newEmptyEntity();
if ($this->request->is('post')) {
$animal = $this->Animal->patchEntity($animal, $this->request->getData());
if(!$animal->getErrors){
$image = $this->request->getData('image_file');
if($image !=NULL){
$name = $image->getClientFilename();
}
if( !is_dir(WWW_ROOT.'img'.DS.'animal-img') ){
mkdir(WWW_ROOT.'img'.DS.'animal-img',0775);
if($name){
$targetPath = WWW_ROOT.'img'.DS.'animal-img'.DS.$name;
$image->moveTo($targetPath);
$animal->image = 'animal-img/'.$name;
}
}
if ($this->Animal->save($animal)) {
$this->Flash->success(__('El animal se ha añadido.'));
return $this->redirect(['action' => 'index']);
}
}
$this->Flash->error(__('El animal no se ha podido añadir, por favor intentalo de nuevo'));
}
$allUsers = $this->getTableLocator()->get('User');
$user = $allUsers->find('list', ['limit' => 200])->all();
$this->set(compact('animal','user'));
}
My table after:

The error:
1) App\Test\TestCase\Controller\AnimalControllerTest::testAdd
Possibly related to PDOException: "SQLSTATE[HY000]: General error: 1364 Field 'id' doesn't have a default value"
…
Failed asserting that 500 is between 200 and 204.
I don't know why this is happening or how to know the reason. In the app the controller works fine. Data in the app:
Data in app
Data in test:
Data in test
I hope someone can help me, I don't know what to try anymore or how to know where the problem is...
I tried to look at the data but it doesn't apear to have any errors so I don't know where the error can be.

Answer 1

It was that the sql file used in the bootstrap didn't have the autoincrement value.
