You want to test a repository method that uses a custom JPQL query with @DataJpaTest. However, the test fails because the query references a table that does not exist. What is the best way to fix this?
AAdd schema.sql or data.sql files to initialize the in-memory database with required tables
BSwitch from <code>@DataJpaTest</code> to <code>@SpringBootTest</code> to load full schema
CAnnotate the test class with <code>@Transactional(propagation = Propagation.NOT_SUPPORTED)</code>
DRemove the custom query and use default repository methods only
Step-by-Step Solution
Solution:
Step 1: Understand in-memory DB setup in @DataJpaTest
The in-memory database starts empty, so tables must be created via schema or data scripts.
Step 2: Fix missing table error
Adding schema.sql or data.sql files initializes tables needed for custom queries.
Final Answer:
Add schema.sql or data.sql files to initialize the in-memory database with required tables -> Option A
Quick Check:
Initialize schema for in-memory DB to fix missing tables [OK]
Quick Trick:Use schema.sql to create tables in @DataJpaTest in-memory DB [OK]
Common Mistakes:
Switching to @SpringBootTest unnecessarily
Disabling transactions instead of fixing schema
Avoiding custom queries instead of fixing DB
