And the line 82 of AppController.php, in public function initialize()

76    $this->loadComponent('Authentication.Authentication',[
77              'requireIdentity'=>true,
78              'logoutRedirect' => '/users/login']);
79
80
81    $this->user=$this->Authentication->getIdentity();
82        $result = $this->Authentication->getResult();
83        if ($result->isValid()) {
84          $identity=$this->Authentication->getIdentity();
85
            ...

What version of the authentication plugin are you using exactly? Look for `"cakephp/authentication"` in your `composer.lock` file if you're not sure. — ndm, Mar 13 '20 at 17:44
Also what exactly does line `82` in your `AppController` do, and in what context is it located? — ndm, Mar 13 '20 at 18:02
"name": "cakephp/authentication", "version": "2.1.0", grep authentication composer.json "cakephp/authentication" : "^2.0", — dype, Mar 14 '20 at 08:05
Seeing from where in the parent it is being invoked, I assume that code is in the controllers `initialize()` method? — ndm, Mar 14 '20 at 11:36

When baking controller tests, bake will create an instance of the related controller class in order to retrieve the default model for that controller, it uses that model to figure the related fixture, which is being added to the $fixtures property of the generated controller test case.

When instantiating a controller, its initialize() method will be invoked at construction time, and that's where you problem starts. You are invoking $this->Authentication->getResult() in your controllers initialize() method, causing the authentication component to look up the required authentication data in the request object attached to the controller, and sure enough it won't find any such data, as no authentication has taken place.

You should move the logic that invokes the authentication component into the controllers beforeFilter() callback method instead, this method will by default only run when the controller factory or the exception renderer invokes the controllers startupProcess() method, which is usually either in an actual HTTP request context, or in the context of a unit test where the possibly required authentication data can be provided.
