Recently I discovered that this code passed our PHPStan level 10 checks: use http\Exception\InvalidArgumentException; // ... throw new InvalidArgumentException; I was surprised as http\Exception\InvalidArgumentException is not a class in our system.

On the Roave Discord recently, there was a discussion about not breaking BC in interfaces inspired by this post by Jérôme Tamarelle: It's clearly true that if you add a new parameter to a method on an interface, then that's a BC break as every concrete implementation of the interface needs to change their signature. However, Gina commented that you…

One of the bigger changes in PHPUnit 10 was the introduction of the new extension system which replaced listeners and hooks. The old way On one of my projects we have a TestListener that sets up the database before we run some functional tests against it.

When I write integration tests with PHPUnit, I find it helpful use Monolog's TestHandler to check that the logs I expect are generated. It's reasonably common that classes that write to a log take a PSR\Log\LoggerInterface in their constructor and then use that for logging. This usually logs to the error handler for pushing to Sentry or whatnot. This makes…
