Question

I am currently trying to run the command php artisan test which should run the test suite however I get the following error

user@earth:/var/www/project/api$ art test -vvv

   ErrorException 

  Object of class Illuminate\Http\JsonResponse could not be converted to int

Given the error is internal to Laravel and the stacktrace all points to the Laravel vendor directory, how do you go about fixing something like this? I currently only have the 2 example tests that ship tests/Feature/ExampleTest.php and tests/Unit/ExampleTest.php.

I did recently upgrade to Laravel 9 but I couldn't see anything in the upgrade notes relating to this

The code seems not be of Laravel 9. Try deleting Vendor folder and removing composer.lock and then run composer install again.

The below is code of execute() method in Laravel 9:

 /**
     * Execute the console command.
     *
     * @param  \Symfony\Component\Console\Input\InputInterface  $input
     * @param  \Symfony\Component\Console\Output\OutputInterface  $output
     * @return int
     */
    protected function execute(InputInterface $input, OutputInterface $output)
    {
        if ($this instanceof Isolatable && $this->option('isolated') !== false &&
            ! $this->commandIsolationMutex()->create($this)) {
            $this->comment(sprintf(
                'The [%s] command is already running.', $this->getName()
            ));

            return (int) (is_numeric($this->option('isolated'))
                        ? $this->option('isolated')
                        : self::SUCCESS);
        }

        $method = method_exists($this, 'handle') ? 'handle' : '__invoke';

        try {
            return (int) $this->laravel->call([$this, $method]);
        } finally {
            if ($this instanceof Isolatable && $this->option('isolated') !== false) {
                $this->commandIsolationMutex()->forget($this);
            }
        }
    }
