If your project is using one of the following for testing (source):
- GPLv2: mariadb
- GPLv2: busybox
- GPLv2 core + LGPLv2 includes with OpenSSL exception: haproxy
- GPLv3: gettext
- GPLv3: adfinis sygroup integration for mariadb

Then please ensure that it is not part of your final project container and document how users may build it themselves.
