Laravel phpunit testing get with parameters

I am writing some tests for my controllers but one of my tests doesn't work. It's supossed to search and get the results back to the page. But it's actually redirecting to the home page. Here is my code:

use DatabaseMigrations;
protected $user;
public function setUp()
{
    parent::setUp();

    $this->seed();

    $this->user = factory(User::class)->create(['role_id' => 3]);
}

/** @test */
public function test_manage_search_user()
{
    $response = $this->followingRedirects()->actingAs($this->user)->get('/manage/users/search', [
        'choices' => 'username',
        'search' => $this->user->username,
    ]);

    $response->assertViewIs('manage.users');
    $response->assertSuccessful();
    $response->assertSee($this->user->email);
}

The URL you should get to make it work look like this:

http://localhost/manage/users/search?choices=username&search=Test

I checked again and it looks like it's not given in the parameters with the get request. How can I fix this?

I had the same issue trying to test GET Requests, you actually can't pass parameter with the $this->get('uri', [header]) but you can by using $this->call, if you check in MakesHttpRequests.php you can see that this->get() is actually using call method.

By adding an array to get method, you are changing the request headers, this is why you are not getting your parameters.

public function get($uri, array $headers = [])
{
    $server = $this->transformHeadersToServerVars($headers);

    return $this->call('GET', $uri, [], [], [], $server);
}

public function call($method, $uri, $parameters = [], $cookies = [], $files = [], $server = [], $content = null)
{
    $kernel = $this->app->make(HttpKernel::class);

    $files = array_merge($files, $this->extractFilesFromDataArray($parameters));

    $symfonyRequest = SymfonyRequest::create(
        $this->prepareUrlForRequest($uri), $method, $parameters,
        $cookies, $files, array_replace($this->serverVariables, $server), $content
    );

    $response = $kernel->handle(
        $request = Request::createFromBase($symfonyRequest)
    );

    if ($this->followRedirects) {
        $response = $this->followRedirects($response);
    }

    $kernel->terminate($request, $response);

    return $this->createTestResponse($response);
}

So if you want to test a GET Request you will have to do this:

$request = $this->call('GET', '/myController', ["test"=>"test"]);

In your controller you should be able to get theses parameters like so:

public function myController(Request $request)
{
    $requestContent = $request->all();
    $parameter = $requestContent['test'];
}
