Siblings () error: InvalidArgumentException: current node list is empty
I have a bug in symfony2 unit testing, symfony: 2.7.1
when I use siblings() I have a the error:
InvalidArgumentException: The current node list is empty. twig file:
<h1>ddd</h1>
<p>ahmedghgh</p>
<ul>
<li>dddd</li>
<li>eeee</li>
<li>ffff</li>
</ul>
</p>bye</p>
<form action ="" method="GET" name ="nameForm">
<input type="text" value ="name" name="name">
<input type="submit" value ="send" name="send">
</form>

<?php

namespace TestingSymfony\BasicBundle\Tests\Controller;
use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;
class BasicControllerTest extends WebTestCase {
public function testHelloContent() {
$client = static::createClient();
$crawler = $client->request('GET', '/helloworld');
$h1 = $crawler->filter('h1')->eq(0);
$p1 = $crawler->filter('p')->first();
$ul = $p1->siblings()->eq(0);
$l1 = $ul->children()->first();
$l2 = $ul->children()->eq(1);
$l3 = $ul->children()->last();
$p2 = $crawler->filterXPath("//p")->last();
}
}
As soon as I remove the siblings everything is fine and no error appears

Yours filter
did not return any results because you had a typo. That's why it crashed. However, for others who didn't have typos, how I resolved this issue by adding a catch attempt.
try {
$p1 = $crawler->filter('p')->first();
} catch (\InvalidArgumentException $e) {
// Handle the current node list is empty..
}
