PHPUNIT Test - Expected Status 200 But Received 500 - laravel

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"?>
<phpunit backupGlobals="false"
backupStaticAttributes="false"

</testsuites>

</whitelist>
</filter>
<php>
<env name="APP_ENV" value="testing"/>

<env name="CACHE_DRIVER" value="array"/>
<env name="SESSION_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.

Answer 3

One possible cause of this error message is, you don't have the openssl
php
extension enabled.

Answer 4

just edit your class to return true
namespace Tests\Feature;
use Tests\TestCase;
use Illuminate\Foundation\Testing\RefreshDatabase;
class ExampleTest extends TestCase
{
/**
* A basic test example.
*
* #return void
*/
public function testBasicTest()
{
$this->assertTrue(true);
}
}
then run test in your command
vendor/bin/phpunit

Answer 5

Do check with your routes. Check if you have provided 'name' to your base route.
eg:
In routes/web.php, Do the following:
Route::get('home','BlogController#home')->name('home');
Now go to the test case and do replace the following code:
$response = $this->get('home');
Let me know if it works for you.
