This commit increases the test coverage of the `internal/app/work` package from 73.1% to over 80% by adding new tests and fixing a bug discovered during testing.
The following changes were made:
- Added tests for the `ListByCollectionID` query in `queries_test.go`.
- Added a unit test for the `NewService` constructor in `service_test.go`.
- Added tests for authorization, unauthorized access, and other edge cases in the `UpdateWork`, `DeleteWork`, and `MergeWork` commands in `commands_test.go`.
- Fixed a bug in the `mergeWorkStats` function where it was not correctly creating stats for a target work that had no prior stats. This was discovered and fixed as part of writing the new tests.
- Updated the `analytics.Service` interface and its mock implementation to support the bug fix.
This commit introduces a new test suite for the `DeleteUser` GraphQL mutation in `internal/adapters/graphql/user_mutations_test.go`. The tests cover successful deletion by an admin and by the user themselves, as well as failure cases for invalid permissions, non-existent users, and invalid input.
During the implementation of these tests, an inconsistency in error handling was discovered. The `internal/data/sql` repositories were using a mix of local and domain-level errors. This has been refactored to consistently use the centralized errors defined in the `internal/domain` package. This change improves the robustness and predictability of the data layer.
The following files were modified to standardize error handling:
- internal/data/sql/base_repository.go
- internal/data/sql/book_repository.go
- internal/data/sql/category_repository.go
- internal/data/sql/copyright_repository.go
- internal/data/sql/country_repository.go
- internal/data/sql/edition_repository.go
- internal/data/sql/email_verification_repository.go
- internal/data/sql/password_reset_repository.go
- internal/data/sql/source_repository.go
- internal/data/sql/tag_repository.go
- internal/data/sql/user_profile_repository.go
- internal/data/sql/user_repository.go
- internal/data/sql/user_session_repository.go
- internal/data/sql/work_repository.go
- internal/data/sql/base_repository_test.go
- internal/data/sql/copyright_repository_test.go
This commit addresses numerous linting errors and improves overall code quality.
- Fixed dozens of 'errcheck' violations by adding error handling and logging for ignored errors, particularly in analytics goroutines and test setup.
- Resolved 'ineffassign' and 'staticcheck' warnings by refactoring variable scopes and suppressing intentional-but-flagged test patterns.
- Removed dead code identified by the 'unused' linter, including helper functions and mock services.
- Refactored test suites to fix inheritance issues, consolidating GraphQL integration tests and correcting test setup logic.
- Corrected invalid logging calls that were causing type check failures.
The codebase now passes 'make lint-test' cleanly.
This commit addresses several high-priority tasks from the TASKS.md file, including:
- **Fix Background Job Panic:** Replaced `log.Fatalf` with `log.Printf` in the `asynq` server to prevent crashes.
- **Refactor API Server Setup:** Consolidated the GraphQL Playground and Prometheus metrics endpoints into the main API server.
- **Implement `DeleteUser` Mutation:** Implemented the `DeleteUser` resolver.
- **Implement `CreateContribution` Mutation:** Implemented the `CreateContribution` resolver and its required application service.
Additionally, this commit includes a major refactoring of the configuration management system to fix a broken build. The global `config.Cfg` variable has been removed and replaced with a dependency injection approach, where the configuration object is passed to all components that require it. This change has been applied across the entire codebase, including the test suite, to ensure a stable and testable application.
Introduced a new testing strategy for the data access layer to avoid redundant testing of generic repository methods.
- Created a comprehensive test suite for the generic `BaseRepository` using a dedicated `TestEntity`. This suite covers all common CRUD operations, including transactions and error handling, in a single location.
- Added a new, focused test suite for `CategoryRepository` that only tests its repository-specific methods, relying on the base repository tests for generic functionality.
- Refactored the existing `AuthorRepository` test suite to remove redundant CRUD tests, aligning it with the new, cleaner pattern.
- Updated the test utilities to support the new testing strategy.
This change significantly improves the maintainability and efficiency of the test suite and provides a clear, future-proof pattern for testing all repositories.
