Session is missing expected key [errors]. Failed asserting that false is true.

Be sure to have Session::start() at the beginning of your test. You can also place this in your setup function if you are using it several places.

@MUSHOOD - That didn't fix it

Can you post your controller code as well?

@MUSHOOD - Here you go:

public function store($channelId, Thread $thread)
{
    try {
        request()->validate(['body' => 'required|spamfree']);

        $reply = $thread->addReply([
            'body' => request('body'),
            'user_id' => auth()->id()
        ]);
    } catch (\Exception $e) {
        return response('Sorry, your reply could not be saved at this time', 422);  
    }

    return $reply->load('owner');
}

@h The validation exception is being caught in your catch and you are returning only this response

return response('Sorry, your reply could not be saved at this time', 422);  

Comment out the try catch block and see if it works

Like this

   // try {
        request()->validate(['body' => 'required|spamfree']);

        $reply = $thread->addReply([
            'body' => request('body'),
            'user_id' => auth()->id()
        ]);
  //  } catch (\Exception $e) {
   //     return response('Sorry, your reply could not be saved at this time', 422);  
   // }

    return $reply->load('owner');

Did not solve it, just caused more errors

This is a similar test that I have in one of my applications

   /** @test */
    public function authors_first_name_is_required_to_store_an_author()
    {
        $this->signIn();
        $author = factory(Author::class)->make([
          'first_name' => null,
          'last_name' => 'Jordan'
      ]);

        $response = $this->post('/authors', $author->toArray())->assertSessionHasErrors(('first_name'));

        $this->assertEquals(0, Author::count());
    }

And my controller look something like this

public method store(Request $request)
{
   $request->validate(['first_name' => 'required', 'last_name' => 'required']);
   //Some more code here to store the author
}

@TRAY2 - Looks very similar but this line won't​ leave the party

Session is missing expected key [errors]

Doesn't​t matter what changes I make

In your controller you have:

request()->validate(['body' => 'required|spamfree']);

You can try to replace it with:

$this->validate(request(), ['body' => 'required|spamfree']);

@SEBRAPONI - That didn't do it :/

I had same problems with assertSessionHasErrors did not figured out exactly why. I believe you can check status because in controller you are sending 422:

$this->post($thread->path().'/athugasemdir', $reply->toArray())
            ->assertStatus(422);

I had similar problem. But problem was in my validation code. I had couple custom Rule class, and one of them throw FatalThrowableError because error in type declarations. So test cant find errors key in that exception because that not validation exception. If you still have same problem try to simplify validation code, i.e. just return 'body'=>'required' to see will the test passed

You cannot immediately go to post. You must start with the form page first.

Please refer to my answer at stackoverflow https://stackoverflow.com/questions/28790348/how-to-test-post-routes-in-laravel/59306188#59306188

I had the same problem, my error is in the phpunit.xml settings missing "<server name =" APP_ENV "value =" testing "/>"

tests

<filter>
    <whitelist processUncoveredFilesFromWhitelist="true">
        <directory suffix=".php">src</directory>
    </whitelist>
</filter>
<php>
    <server name="APP_ENV" value="testing"/>
</php>

Only solution which worked is recommended here: https://stackoverflow.com/questions/57036898/laravel-5-8-nova-login-test-session-is-missing-expected-key-errors

I realize this is an old post, but you might try using withoutExceptionHandilng() to see if there is something else going on. Laravel might be handling an underlying exception for you.

You can use assertSessionHasErrors like this

    public function validate_contact_type()
    {
        $this->createContact(['type' => null])
            ->assertSessionHasErrors(['type']);
    }

I know this thread is old, but I had the same problem, and found a different cause (after a really long time). In my case, the test previously worked, then stopped working, without me making any changes to the test code. A series of related tests also failed. Specifically, when testing for a redirect, I also got the error:

Response status code [419] is not a redirect status code.

when testing a redirect that came after validation.

As it turns out, some other change I had made had caused Laravel to run its configuration caching. It seems this breaks Laravel's ability to disable its VerifyCsrfToken middleware during PHPUnit tests. The session failing to register errors was just a run-on effect of it running Csrf verification when it shouldn't.

The solution turns out to be:

1. Run "php artisan config:clear"
2. Never run "php artisan config:cache" or anything that might make it run, in development.
