Issues with integration tests after upgrading to 8.1.3

[NormySan]

Hi,

I just upgraded to version 8.1.3 in my Symfony application. I don't use the Symfony bundle and just bootstrap everything on my own which works great. After upgrading everything works as expected when querying the API through the browser but my integration tests have all stopped working. I'm extending the Symfony WebTestCase in my tests and making authenticated JSON requests against the API endpoint. When I make requests it never finishes executing and it doesn't crash it just sits there forever without returning a response. Has anyone encountered a similar issue after upgrading?

Edit:
I've narrowed it down to being an issue with a change that happened in the 8.0.0 release. When I go down to version 7.0.0 it all starts working again so I'm thinking that it might be related to the cache changes.

@NormySan error logs is a start. Without that, we can't really help.

There are no errors thats the main issue. It just completely stops and never finishes executing the test. I was mostly writing here to see if anyone else has encountered a similar issue after upgrading.

I'm working on reproducing it in a separate smaller repository but have not managed to do so yet so might be something else interfering or packages that don't get along.

You're going to need to debug your webserver then. What webserver are you using? What are your timeouts? Are the workers crashing? Are they still running? What's the CPU/memory overhead, etc.?

I found the issue. The new kcs/class-finder attempted to load all of the files in our tests directory and in that directory we have a boostrap.php file that runs a bunch of commands to set up our database, run migrations and run fixtures and when the class finder attempts to autoload this it will end up in an infinite loop or won't be able to execute the commands in this file.

The solution was to set a finder to the schema factory that excludes our test namespace like this:

$factory->setFinder(new ComposerFinder()->notInNamespace('Company\\App\\Tests'));
