95-110: Critical: Mock server created but never used.

Same issue as the previous test - the mock server (lines 98-102) is created to simulate an API error response, but the test calls the real API instead (line 106).


112-136: Critical: Mock server created but never used.

Same issue - the mock server simulating an empty response (lines 124-128) is never actually used by the test (line 132).


233-248: Critical: Mock server created but never used.

The test creates a mock server returning invalid JSON (lines 236-239) but then calls the real API with "invalid-key" (line 244) instead of using the mock.

🧹 Nitpick comments (4)
internal/gemini/gemini_test.go (1)

101-109: Drop or rework the “context cancellation” test

This subtest only repeats the “invalid key” assertion you already cover elsewhere, while the comment admits context isn’t wired yet. Until the production function accepts a context.Context, this brings zero new signal. Please either implement context handling and assert it here, or remove the subtest to keep the suite focused.

internal/grok/grok_test.go (1)

38-176: Refactor the “mock server” tests to exercise real success paths

Each subtest here stands up an httptest server but still calls GenerateCommitMessage with "invalid-key". Because the production code doesn’t accept an override for the base URL/client, none of these handlers ever run — the call exits early with the same invalid-key error you already assert elsewhere. That makes the whole block misleading and duplicative. Please either add injection points (e.g., allow passing an HTTP client/base URL) so the mock server is actually hit and you can assert on the request/response, or drop these subtests entirely.

internal/chatgpt/chatgpt_test.go (1)

33-46: Remove the unused mock server (or make the client injectable)

This subtest spins up an httptest server but GenerateCommitMessage never points at it; the code still calls the real OpenAI endpoint and immediately fails with the invalid key, so the handler is dead code. Please either expose an injectable HTTP client/base URL so the server is exercised, or drop the mock to keep the test honest.

internal/claude/claude_test.go (1)

250-261: Add a mock-server assertion for long-prompt handling
The current test only asserts an error on an invalid API key and never inspects the request body. In TestGenerateCommitMessageWithLongPrompt, spin up an httptest.NewServer to capture the JSON payload and assert that:

  • the prompt sent (req.Messages[0].Content) contains (or is truncated to) the expected length (e.g. ≥1000 bytes)
  • no unintended modifications occur before sending
  • the function succeeds with a valid API key and returns the expected response

13-33: LGTM! Input validation tests are correct.

The basic validation tests for empty API key and empty changes are well-structured and correctly use t.Parallel() for concurrent execution.


155-190: LGTM! Serialization test is thorough.

The test correctly verifies that ClaudeRequest can be marshaled and unmarshaled, checking all fields including model, max tokens, and messages.


192-231: LGTM! Deserialization test is comprehensive.

The test properly validates that ClaudeResponse JSON can be parsed and that all fields (ID, Type, Content array) are correctly deserialized.

🛠️ Refactor suggestion | 🟠 Major

Consider refactoring GenerateCommitMessage to accept URL parameter.

Multiple tests throughout the file create mock servers but cannot use them because GenerateCommitMessage hardcodes the API URL. The recurring comment "This would require modifying the function to accept a URL parameter" appears in lines 85-86, 104-105, 130-131, and 242-243.

Options to fix this:

  1. Add an optional URL parameter to GenerateCommitMessage
  2. Use dependency injection to pass in an HTTP client
  3. Create a separate internal helper function that accepts a URL for testing

This refactor would enable all the mock server tests to actually test the function logic.

Would you like me to generate a refactored version of the GenerateCommitMessage function signature that supports testing with mock servers?

🤖 Prompt for AI Agents
internal/claude/claude_test.go lines 1-261: tests create httptest servers but
cannot use them because GenerateCommitMessage hardcodes the API URL; update the
function to accept an injectable API endpoint (or HTTP client) so tests can pass
server.URL. Change GenerateCommitMessage signature to accept an extra apiURL
string (or an optional client) and in production calls pass the default
"https://api.anthropic.com/v1/messages" when apiURL is empty; update all
internal callers and tests to provide the mock server URL (or a test HTTP
client), and ensure backward-compatible behavior by defaulting to the original
URL when the new parameter is not provided.

⚠️ Potential issue | 🔴 Critical

Critical: Mock server created but never used.

The test creates a mock httptest.Server with expectations (lines 55-79) but then calls GenerateCommitMessage with the real API URL and an "invalid-key" (line 87). This means:

  1. The mock server is never exercised
  2. The test makes actual network calls to Claude's API (which will fail)
  3. None of the server's assertions (HTTP method, headers, request body) are verified

To fix this, the GenerateCommitMessage function needs to accept a configurable API URL parameter (as the comment on lines 85-86 suggests), or use dependency injection for the HTTP client.

Apply this pattern to make the mock server useful:

-// This would require modifying the function to accept a URL parameter
-// For now, we'll test the error handling path
-_, err := GenerateCommitMessage(&types.Config{}, "some changes", "invalid-key", nil)
-if err == nil {
-	t.Fatal("expected error for invalid API key")
-}
-
-_ = originalURL // Avoid unused variable warning
+// Modify GenerateCommitMessage to accept a URL parameter or use dependency injection
+result, err := GenerateCommitMessageWithURL(&types.Config{}, "some changes", "test-key", nil, server.URL)
+if err != nil {
+	t.Fatalf("unexpected error: %v", err)
+}
+
+if result != "feat: add new feature" {
+	t.Fatalf("expected 'feat: add new feature', got %s", result)
+}

🤖 Prompt for AI Agents
In internal/claude/claude_test.go around lines 55 to 93, the httptest.Server is
created but never used because GenerateCommitMessage calls the real API URL;
change GenerateCommitMessage to accept an API base URL (or an options struct
that includes apiURL and http.Client) with a sane default of
"https://api.anthropic.com/v1/messages", update all call sites to pass the new
parameter or default, then update this test to call GenerateCommitMessage with
server.URL as the API base and a matching API key so the mock server is
exercised and its assertions are verified; ensure backward-compatible defaults
and update tests accordingly.

⚠️ Potential issue | 🔴 Critical

🧩 Analysis chain

Test doesn't verify style instructions are included.

The test creates GenerationOptions with style instructions (lines 143-146) but only verifies that an error occurs with an invalid key. It doesn't confirm that the style instructions are actually incorporated into the prompt sent to the Claude API.

To properly test this, use a mock server to capture and inspect the request body.

After fixing the mock server issues, verify that the style instructions appear in the request:

server := httptest.NewServer(http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
	var req ClaudeRequest
	json.NewDecoder(r.Body).Decode(&req)
	
	// Verify style instruction is in the prompt
	prompt := req.Messages[0].Content
	if !strings.Contains(prompt, "Use a casual tone") {
		t.Fatal("style instruction not included in prompt")
	}
	
	// Verify attempt number is handled
	if opts.Attempt > 1 && !strings.Contains(prompt, "alternative") {
		t.Fatal("attempt number not reflected in prompt")
	}
	
	// Return mock response
	w.Header().Set("Content-Type", "application/json")
	json.NewEncoder(w).Encode(ClaudeResponse{...})
}))

Add assertions for style instructions and attempt in TestGenerateCommitMessageIncludesStyleInstructions
TestGenerateCommitMessageIncludesStyleInstructions only checks for an error and doesn’t verify that opts.StyleInstruction (“Use a casual tone”) or opts.Attempt (e.g. “alternative”) appear in the prompt sent to Claude. Use httptest.NewServer to capture the JSON request, then assert that req.Messages[0].Content contains both the StyleInstruction and a reference to the attempt number. [internal/claude/claude_test.go:139]

🤖 Prompt for AI Agents
In internal/claude/claude_test.go around lines 139 to 153, the test only
verifies an error for an invalid API key and does not assert that the style
instruction or attempt number are present in the prompt sent to Claude; replace
the invalid-key flow with an httptest.NewServer that captures the JSON request
body, parse the request to extract the sent messages, and add assertions that
the message content includes opts.StyleInstruction ("Use a casual tone") and a
clear reference to opts.Attempt (e.g., "Attempt 2" or the attempt number string
you embed); configure the test Config to point the client to the test server URL
and use a dummy valid key so GenerateCommitMessage returns without an API-key
error, then assert the captured request contains both the style instruction and
the attempt reference before finishing the test.

⚠️ Potential issue | 🟠 Major

Fix the stream assertion — it can never pass

GenerateCommitMessage currently marshals the OllamaRequest struct (see internal/ollama/ollama.go lines 14-17), which only carries model and prompt. No stream field is emitted, so decoding the request into a map leaves req["stream"] undefined (nil). This assertion will fail every run, blocking the suite. Either add a stream field to the real request payload or, if streaming is intentionally unmanaged, drop this expectation. Suggested quick fix if you decide to keep today’s payload:

-			if req["stream"] != false {
-				t.Fatalf("expected stream false, got %v", req["stream"])
-			}
+			if _, ok := req["stream"]; ok {
+				t.Fatalf("stream flag is not sent today; got %v", req["stream"])
+			}
