There was 1 error:
1) Tests\Feature\AlphaTest::testDisplaysAlpha
Error: Call to undefined method Tests\Feature\AlphaTest::visit()
C:\wxxx\www\testxxxxxxxxx\tests\Feature\AlphaTest.php:18
ERRORS!
Tests: 4, Assertions: 9, Errors: 1.

And here is the test case source code :

<?php

namespace Tests\Feature;

use Tests\TestCase;
use Illuminate\Foundation\Testing\RefreshDatabase;

class AlphaTest extends TestCase
{
    public function testDisplaysAlpha()
    {
        $this->assertTrue(true);
        $this->visit('/alpha')
             ->see('Alpha')
             ->dontSee('Beta');
    }
}

There is no visit method built-in by default in Laravel 5.5. It uses dusk to perform browser tests and the method visit() is not available anymore. If you still wanted to use those behavior, install laravel/browser-kit-testing package :

composer require laravel/browser-kit-testing --dev

More reference  about browser-kit-testing reference this:
https://github.com/laravel/browser-kit-testing#laravel-browserkit-testing

After finished installing laravel/browser-kit-testing package to your laravel 5.5 project , edit your \test\TestCase.php from the default one to this:

<?php

namespace Tests;

//use Illuminate\Foundation\Testing\TestCase as BaseTestCase;
use Laravel\BrowserKitTesting\TestCase as BaseTestCase;

abstract class TestCase extends BaseTestCase
{
    use CreatesApplication;
    public $baseUrl = 'http://localhost';
}

What we need to do is import Laravel\BrowserKitTesting\TestCase as BaseTestCase instead of Illuminate\Foundation\Testing\TestCase as BaseTestCase; and then default a value named $baseUrl.

Run your test again :

Since this is the old method, it's recommend to learn using another alternative : Laravel Dusk to run full browser tests
