Falha em teste unitário

Java

Olá pessoal,

sou novo em programação Java com Spring Boot e estou desenvolvendo um sistema de gerenciamento de negócios de um comércio de compra e venda de café. Ao executar o teste de um Service, apresenta 2 falhas, tanto no método de buscar por lote, quanto no método de persistir no banco. Estou utilizando um profile de teste e um banco H2 (em memória) para testar e um Mock Object (objeto falso) para representar meu repositório. Não estou entendendo o motivo das falhas.

Alguém poderia me ajudar, por favor?
