If I run my tests using PHP7.2 or PHP7.1 they are about 3x slower than if I run them using PHP7.0. Is there anyway to get to the bottom of why this is happening?
I'm using Laravel 5.5.20 and Laravel Homestead 7.0.1. I have 47 rather simple tests, some hitting the database, others just simple assertions; so there isn't anything that should take ages.
I installed johnkary/phpunit-speedtrap to see which tests take the longest so I could remove those but there isn't a specific test that takes a long time because if I remove the offending test, the next one will take ages (see below).
First Run Second Run Test A 0.2 sec Test A 0.2 sec Test B. 0.3 sec Test B. 0.3 sec Test C 0.1 sec Test C 0.1 sec Test D 0.1 sec Test D 0.1 sec Test E 9.3 sec REMOVED Test E Test F 0.3 sec Test F 9.3 sec <-- Test F now takes ages Test G 0.2 sec Test G 0.2 sec
I am also using an in-memory SQLite3 database, with the Laravel
RefreshDatabase trait as I want each test to run independently.
I do not have Xdebug installed or running. Is there something known that PHP7.1 and PHP7.2 take a long time to run PHPUnit tests? Is there something else I can install (or even run it with Xdebug) to track down what exactly it is that is causing the issue?
