## Build matrix for lowest and highest possible targets
matrix:
  include:

## Install or update dependencies
install:
  - composer validate
  - if [ "$coverage" = "false" ]; then phpenv config-rm xdebug.ini || :; fi;
  - if [ -z "$dependencies" ]; then composer install --prefer-dist; fi;
  - if [ "$dependencies" = "lowest" ]; then composer update --prefer-lowest --prefer-dist -n; fi;
  - if [ "$dependencies" = "highest" ]; then composer update --prefer-dist -n; fi;
  - composer show

## Run the actual test
script:
  - if [ "$coverage" = "false" ]; then make ci; fi;
  - if [ "$coverage" = "true" ]; then make ci-with-coverage; fi;

## Gather coverage and set it to coverage servers
after_script: make ci-coverage
