Test Coverage

[MaximumTrainer]

Gap

Only four backend test files exist:

• OpenDataMaskApplicationTests.kt (context load test)
• AuthControllerTest.kt
• AuthServiceTest.kt
• WorkspaceServiceTest.kt

Missing test coverage:

• Connector tests (PostgreSQLConnector, MongoDBConnector, AzureSQLConnector, MongoDBCosmosConnector).
• DataConnectionService and DataConnectionController tests.
• TableConfigurationService and TableConfigurationController tests.
• JobService and JobController tests.
• EncryptionService tests.
• JwtTokenProvider and JwtAuthenticationFilter tests.
• Frontend: no test files found despite Vitest being configured.
• CLI: no Go test files found.

Affected files:

• backend/src/test/
• frontend/ (test files)
• cli/ (test files)

Required Work

• Add unit tests for all services and controllers (target ≥ 80% line coverage).
• Add connector integration tests (use Testcontainers or mocks).
• Add frontend component and API tests using Vitest.
• Add Go CLI tests using testing package.
• Set up CI pipeline for automated test execution.
