PHP-VCR 1.5.0 generates fatal error with wp_remote_post and wp_remote_get from WordPress

[felipead]

I'm trying to record some HTTP requests generated by WordPress HTTP functions, such as wp_remote_post and wp_remote_get.

When using PHP-VCR 1.4.5, I get the error described in #327. After upgrading to PHP-VCR 1.5.0 (latest), I get the following fatal error:

Installing...

This is the test code:

class Example_TestCase extends WP_UnitTestCase {

    public function test_should_get_index_from_example_com() {
        VCR::turnOn();
        VCR::insertCassette( 'get_example_com.yml' );

        $response = wp_remote_get( 'http://example.com' );

        print_r( $response );

        VCR::eject();
        VCR::turnOff();
    }
}

When I run this test using php-unit, an empty get_example_com.yml cassette file is generated, without any HTTP requests being recorded. I only get the fatal error described above.

I have tested it with endpoints from Google, Facebook, and other sites. It does not seem related to any particular website.

Environment

I'm running WordPress 5.2.4 and PHP 7.

I'm using PHP-VCR version 1.5.0 (latest) installed through Composer. Unfortunately, I couldn't test it PHP-VCR version 1.5.0.

I'm running tests in this Docker container, which is based on the php-unit/php-unit:6.0.6 image. If you look at the Dockerfile, you can see this image has PHP 7 installed through Alpine and all necessary dependencies, including curl and php7-curl.

Which version of the Symfony event dispatcher are you using?

Which version of the Symfony event dispatcher are you using?

Symfony event dispatcher has been automatically installed as a php-vcr dependency by Composer. Looking at composer.lock I can see it is using Symfony event dispatcher version 5.1.3.
