tests in `internal/services/analyzer_llm_test.go` +- Added deterministic mock seam for OpenAI requests in `internal/services/analyzer.go` +- Added 2-minute timeout context to OpenAI calls in `internal/services/analyzer.go` +- **1.x and 2.x test cases are now passing** (with 1.2.6 intentionally skipped) **Key Achievements:** -✅ Error handling tests all pass - system properly rejects: - - Non-PDF files (DOCX, JPEG) - - Corrupted PDFs - - Empty PDFs - - Null/empty readers +✅ End-to-end coverage for PDF extraction scenarios (1.x) +✅ Full callLLM behavior coverage for auth, request shape, timeout, parsing, and upstream failures (2.x) +✅ Reproducible, offline test behavior via OpenAI request mocking **Next Steps:** -1. Refine PDF generation for valid PDF test cases (1.1.x, 1.3.x) -2. Options: - - Use external PDF creation tool (Python reportlab, etc.) - - Load pre-generated test PDF files - - Use Go PDF library like gopdf -3. Continue with Section 2 (OpenAI API Integration) tests -4. Run full integration tests once Section 1 complete +1. Add CI step to run `go test ./...` before image build/push +2. Tighten manual validation notes for production-like OpenAI calls +3. Backfill health-check endpoint or document non-AI endpoint strategy +4. Keep the intentional 1.2.6 skip documented until encrypted-PDF fixtures are added ### Coverage Report - [ ] All SRD Functional Requirements covered diff --git a/internal/api/integration_test.go b/internal/api/integration_test.go new file mode 100644 index 0000000..6055e31 --- /dev/null +++ b/internal/api/integration_test.go @@ -0,0 +1,163 @@ +package api + +import ( + "bytes" + "fmt" + "io" + "mime/multipart" + "net/http" + "net/http/httptest" + "sync" + "testing" + "time" + + "github.com/go-chi/chi/v5" + + "git.gophernest.net/azpect/ResumeLens/internal/handlers" + "git.gophernest.net/azpect/ResumeLens/internal/models" +) + +func makeAnalyzeRequest(t *testing.T, ip string) *http.Request { + t.Helper() + body := &bytes.Buffer{} + w := multipart.NewWriter(body) + + part, err := w.CreateFormFile("resume", "resume.pdf") + if err != nil { + t.Fatalf("create form file: %v", err) + } + if _, err := part.Write([]byte("fake-pdf"));
