From 48c6f38002d89dc143d38ce611b2c59808c60637 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Mon, 26 May 2025 01:35:42 +0000 Subject: [PATCH] feat: Add comprehensive unit tests and refactor for testability This commit introduces unit tests for major parts of the application, including authentication logic, chirp handlers, and login handlers. Key changes: - Added unit tests for `internal/auth/auth.go`, covering password hashing, JWT operations, and token/API key extraction. - Added unit tests for `handler_chirps.go`, including chirp creation, retrieval, deletion, and body cleaning. This required: - Modifying `handler_chirps.go` to use `chi.URLParam()` for path parameters to enable easier testing. - Added unit tests for `handler_login.go`, covering user login, token refresh, and token revocation. To support testability, the following refactoring was performed: - The `db` field in `main.apiConfig` was changed from a concrete `*database.Queries` type to a `database.Querier` interface. A `Querier` interface was defined in `internal/database/db.go` encompassing all necessary database methods. - Key authentication functions (`ValidateJWT`, `GetBearerToken`, `GetAPIKey`) were made injectable by adding them as fields to `main.apiConfig`. Handler functions were updated to use these injectable functions. Finally, `README.md` was updated with a "Running Tests" section, instructing you on how to execute the test suite using `go test ./...`. The tests for `GetAPIKey` and `GetBearerToken` in `internal/auth/auth_test.go` correctly fail for specific edge cases where the token/key string is empty after the prefix, as the underlying functions do not currently return errors for these inputs. These functions were not modified as part of this work. --- README.md | 10 + go.mod | 2 + go.sum | 2 + handler_chirps.go | 19 +- handler_chirps_test.go | 536 +++++++++++++++++++++++++++++++++++++
