PHPUNIT Test - Expected Status 200 But Received 500

Question

I keep getting status 500 when 200 is expected. These are the files:

ExampleTest.php

namespace Tests\Feature;

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

class ExampleTest extends TestCase
{
    /**
     * A basic test example.
     *
     * @return void
     */
    public function testBasicTest()
    {
        $response = $this->get('/');

        $response->assertStatus(200);
    }
}

phpunit.xml

<?xml version="1.0" encoding="UTF-8"?>

         backupStaticAttributes="false"

        <testsuite name="Feature">
            <directory suffix="Test.php">./tests/Feature</directory>
        </testsuite>
    </testsuites>
    <filter>
        <whitelist processUncoveredFilesFromWhitelist="true">
            <directory suffix=".php">./app</directory>
        </whitelist>
    </filter>
    <php>
        <env name="APP_ENV" value="testing"/>
        <env name="BCRYPT_ROUNDS" value="4"/>
        <env name="CACHE_DRIVER" value="array"/>

        <env name="QUEUE_CONNECTION" value="sync"/>
        <env name="MAIL_DRIVER" value="array"/>
    </php>
</phpunit>

This is the result returned

Any help is greatly appreciated.

Answer 1

Try to use RefreshDatabase trait in the test class:

use Illuminate\Foundation\Testing\RefreshDatabase;

class ExampleTest extends TestCase
{
    use RefreshDatabase;

    public function testBasicTest()
    {
        $response = $this->get('/');

        $response->assertStatus(200);
    }
}

Answer 2

add $this->withoutExceptionHandling(); before $response = $this->get('/'); to get more information about the error.
