Unable to run PHPUnit tests inside the containers

[mxr576]

After the latest changes introduced in the PHP 7.1-4.1.0 I am unable to run Drupal 8's PHPunit tests inside the container because all Functional/Kernel tests fails with the following error.

Exception: User warning: mkdir(): Permission Denied
Drupal\Component\PhpStorage\FileStorage->createDirectory()() (Line: 173)

Checked the path, it complains about the sites/simpletest/45573929/files/php and sites/simpletest/45573929/files owned by wodby:wodby.

As a temporary "solution" I could solve this problem by restoring www-data's wodby group membership.

Have you tried to run it via sudo as mentioned in https://www.drupal.org/docs/8/phpunit/running-phpunit-tests? In -dev images sudo allowed for all commands for wodby user

[mxr576]

I think for that a similar rule like this is missing from sudoers, if I would like to execute tests as www-data in a shell script.

wodby ALL=(www-data:ALL) NOPASSWD:SETENV:ALL

or should I use the sudo -u root -E sudo -u www-data -E whoami syntax?

Take a look at this: https://www.drupal.org/project/drupal/issues/2867042 I think that may be what you're running up against.

Solved by using "dev" images and running test with sudo -u root -E sudo -u www-data -E vendor/bin/phpunit ...
