13-25: LGTM! Consider adding return type documentation.The setup function correctly mirrors the production configuration. Consider adding a comment describing the return value for better documentation.
-func setupApp() *fiber.App { +// setupApp initializes and returns a configured Fiber application instance for testing +func setupApp() *fiber.App {
33-33: Document timeout configuration.The
-1timeout value should be documented to explain why infinite timeout is necessary for tests.- resp, _ := app.Test(req, -1) // -1 disables timeout + // Use -1 to disable timeout in test environment to prevent flaky tests + resp, _ := app.Test(req, -1)
47-57: Enhance 404 test coverage.While the status code check is good, consider also verifying the response body for completeness.
// Check the response assert.Equal(t, http.StatusNotFound, resp.StatusCode) + + // Verify response body + body := make([]byte, resp.ContentLength) + _, err := resp.Body.Read(body) + if err != nil { + t.Fatalf("Failed to read response body: %v", err) + } + defer resp.Body.Close() + assert.Equal(t, "Not Found", string(body))404-handler/README.md (1)
87-91: Enhance test setup instructions.Consider adding version requirements for testify and explaining why it's the chosen testing framework.
## Testing -1. `go get github.com/stretchr/testify/assert` -2. `go test -v` +1. Install the testify package for enhanced testing capabilities: + ```bash + go get github.com/stretchr/testify/assert@latest + ``` + +2. Run the tests: + ```bash + go test -v + ``` + +The testify package is used for its expressive assertion syntax and comprehensive testing utilities.

Handle potential read errors.
The response body read operation should handle potential errors.
- body := make([]byte, resp.ContentLength)
- resp.Body.Read(body)
+ body := make([]byte, resp.ContentLength)
+ _, err := resp.Body.Read(body)
+ if err != nil {
+ t.Fatalf("Failed to read response body: %v", err)
+ }📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
| body := make([]byte, resp.ContentLength) | |
| resp.Body.Read(body) | |
| defer resp.Body.Close() | |
| body := make([]byte, resp.ContentLength) | |
| _, err := resp.Body.Read(body) | |
| if err != nil { | |
| t.Fatalf("Failed to read response body: %v", err) | |
| } | |
| defer resp.Body.Close() |

🛠️ Refactor suggestion
Remove redundant code example.
The code example at the end of the README is redundant as it's already shown in the "Code Overview" section above.
Consider removing lines 192-232 to avoid duplication and potential maintenance issues when the code changes.
