# Testing Guide
This repository includes a growing test suite designed to be realistic and robust.
Key patterns:
- Table‑driven tests: consolidate repetitive scenarios into concise tables (see `internal/lsp/*_table_test.go`).
- Shared fixtures: use `internal/testutil/fixtures.go` for multi‑line docblocks, chat replies, function suggestions, and markdown fences.
- Provider mocks: use `httptest.Server` and/or custom `http.RoundTripper` to simulate OpenAI/Copilot/Ollama responses, including success, stream (SSE), and error cases.
- E2E LSP tests: capture JSON‑RPC frames from the in‑memory server (`captureResponse`, `captureRequest`) and validate code actions, resolves, and chat edits.
Suggested additions:
- Expand table‑driven coverage for completion edit computations and label/filter selection.
- Add more negative tests (malformed SSE/JSON payloads) to assert robust error handling.
## Running Tests
- Full suite with coverage:
- `HEXAI_TEST_SKIP_NET=1 go test ./... -cover`
- The `HEXAI_TEST_SKIP_NET=1` env var disables any tests that require network access, keeping runs deterministic in CI/sandboxes.
- Package-specific runs:
- `HEXAI_TEST_SKIP_NET=1 go test ./cmd/internal/hexai-action -cover`
- `HEXAI_TEST_SKIP_NET=1 go test ./internal/hexaiaction -cover`
Notes
- Some environments restrict writes to the Go build cache; if you see cache permission errors, re-run in a less-restricted shell or allow the command to write to the cache.
- Always format Go code before committing: `gofumpt -w .`
