How can I detect 404 errors for page assets? - selenium

Question

I've just gotten started with Behat and Mink. I'm using MinkExtension with Goutte and Selenium, and also DrupalExtension.
So far, so good. I can load a page, look for various elements, test links, etc.
But I don't see how to check for 404s on various assets - images, especially, but also css and js files.
Any tips or examples would be much appreciated.

Answer 1

When using Goutte web crawler you can do this:
$crawler = $client->request('GET', 'http://your-url.here');
$status_code = $client->getResponse()->getStatus();
if($status_code==404){
// Do something
}

Answer 2

You can try the following methods:
<?php
use Behat\Behat\Context\Context;
use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;
use Symfony\Bundle\FrameworkBundle\Client;
class FeatureContext extends WebTestCase implements Context {
/**
* #var Client
*/
private $client;
/**
* #When /^I send a "([^"]*)" request to "([^"]*)"$/
*
* #param $arg1
* #param $arg2
*/
public function iSendARequestTo($arg1, $arg2) {
$this->client = static::createClient();
$this->client->request($arg1, $arg2);
}
/**
* #Then /^the output should contain: "([^"]*)"$/
*
* #param $arg1
*/
public function theOutputShouldContain($arg1) {
$this->assertContains($arg1, $this->client->getResponse()->getContent());
}
/**
* #Then /^the status code should be "([^"]*)"$/
*
* #param $arg1
*/
public function theStatusCodeShouldBe($arg1) {
$this->assertEquals($arg1, $this->client->getResponse()->getStatusCode());
}
}

Please check the following methods from this HelperContext.php (part of CWTest_Behat):
/**
* #Given get the HTTP response code :url
* Anonymous users ONLY.
*/
public function getHTTPResponseCode($url) {
$headers = get_headers($url, 1);
return substr($headers[0], 9, 3);
}
/**
* #Given I check the HTTP response code is :code for :url
*/
public function iCheckTheHttpResponseCodeIsFor($expected_response, $url) {
$path = $this->getMinkParameter('base_url') . $url;
$actual_response = $this->getHTTPResponseCode($path);
$this->verifyResponseForURL($actual_response, $expected_response, $url);
}
/**
* Compare the actual and expected status responses for a URL.
*/
function verifyResponseForURL($actual_response, $expected_response, $url) {
if (intval($actual_response) !== intval($expected_response)) {
throw new Exception("This '{$url}' asset returned a {$actual_response} response.");
}
}
/**
* #Given I should get the following HTTP status responses:
*/
public function iShouldGetTheFollowingHTTPStatusResponses(TableNode $table) {
foreach ($table->getRows() as $row) {
$this->getSession()->visit($row[0]);
$this->assertSession()->statusCodeEquals($row[1]);
}
}
Here are the example scenarios written in Behat which are using the above methods:
#roles #api #regression
Scenario: Verify Anonymous User access to /user/login
Given I am not logged in
Then I check the HTTP response code is 200 for '/user/login'
#roles #api #regression
Scenario: Verify Anonymous User access to /admin
Given I am not logged in
Then I check the HTTP response code is 403 for '/admin'
#roles #api #regression
Scenario: Verify Administrator access to /admin
Given I am logged in as a user with the admin role
And I am on "/admin"
Then the response status code should be 200

It's possible to use Restler, a micro framework which can help with RESTful API testing in Behat. It support behavior Driven API testing using Behat and Guzzle.
Check the following example:
Scenario: Saying
When I request "/examples/_001_helloworld/say"
Then the response status code should be 404
And the response is JSON
And the type is "array"
