I have tried php unit 7.5.20 and 5.7.27 and both are having the same issues.

Attaching the error I’m seeing  
Output in circleci :  
PHPUnit 5.7.27 by Sebastian Bergmann and contributors  
wp\_die called  
Exited with code exit status 255

I have ssh into machine and saw the error that is causing the exit status  
$ ./vendor/bin/phpunit --configuration phpunit.xml --log-junit $HOME/phpunit/junit.xml
