Chargement des propriétés de test application.yml

Assurez-vous de vérifier la structure de votre projet. Le fichier de propriétés doit se trouver sur le chemin de classe pour que Spring Boot le trouve et l'utilise. Par exemple, la structure du projet telle que définie par Maven ici: https://maven.apache.org/guides/introduction/introduction-to-the-standard-directory-layout.html

Dans le cas de Maven, vos fichiers de configuration doivent être placés dans ces répertoires:

src/main/resources/application.yml
src/test/resources/application.yml

Il semble que le bean n'est pas créé (d'où l'erreur nulle).

Essayez de:

• ajoutez @Configuration au-dessus de votre classe de configuration SnmpProperties
• ajoutez @EnableConfigurationProperties(SnmpProperties.class) en haut de votre classe de test
