This addon provides grouping for the fluid templating in EXT:solr.
Caution: solrfluidgrouping is part of solr 12+, so there will be no release for TYPO3 12.
First you need to set some environment variables and boostrap the system with the bootstrap script (you only need to do this once), the bootstrapper will ask you for some variables (TYPO3 version, EXT:solr version, db host, db user and db passwort) that are needed for the integration tests:
chmod u+x ./Build/Test/*.sh
source ./Build/Test/bootstrap.sh --local
Now you can run the complete test suite:
./Build/Test/cibuild.sh
