PHPUnit et GitLab CI/CD

Bonjour,

Je rencontre un problème concernant la pipeline GitLab et un projet symfony.

J'ai un fichier .gitlab-ci.yml que j'utilise depuis pas très longtemps après l'avoir essayé sur deux projet vierge je n'ai pas de problème.

Par contre j'ai un projet où je souhaite utiliser la pipeline de GitLab et j'ai donc ouvert un repo privé dessus avec une branch dev pour essayer de la mettre en place.

Problème pas moyen d'excéuter les tests unitaires de la pipeline (fonctionne en local).

Du coup, je ne sais pas si cela vien du fichier ou du projet (je dirais le projet :p )

Ce que je fais

Voici mon fichier .gitlab-ci.yml

  - composer install --no-scripts

    - vendor/
