```
---
## Test Patterns
### Table-Driven Tests
Most tests use Go's table-driven test pattern for comprehensive coverage:
```go
func TestRuleMin(t *testing.T) {
tests := []struct {
name string
field string
value string
param string
hasError bool
}{
{"Valid - meets minimum", "msg", "hello", "5", false},
{"Valid - exceeds minimum", "msg", "hello world", "5", false},
{"Invalid - too short", "msg", "hi", "5", true},
{"UTF-8 aware - valid", "name", "Jose", "4", false},
}
for _, tt := range tests {
t.Run(tt.name, func(t *testing.T) {
result := ruleMin(tt.field, tt.value, tt.param)
if (result != nil) != tt.hasError {
t.Errorf("ruleMin(%q, %q, %q) error = %v, wantError %v",
tt.field, tt.value, tt.param, result != nil, tt.hasError)
}
})
}
}
```
### HTTP Handler Testing
Using `net/http/httptest` for handler tests:
```go
func TestHandleError_JSON(t *testing.T) {
appErr := NewAppError(nil, "Bad request", http.StatusBadRequest, false)
req := httptest.NewRequest(http.MethodGet, "/", nil)
req.Header.Set(c.HeaderAccept, c.ContentTypeJSON)
rec := httptest.NewRecorder()
HandleError(rec, req, appErr)
if rec.Code != http.StatusBadRequest {
t.Errorf("Status = %d, want %d", rec.Code, http.StatusBadRequest)
}
var response ErrorResponse
if err := json.Unmarshal(rec.Body.Bytes(), &response); err != nil {
t.Fatalf("Failed to parse JSON response: %v", err)
}
}
```
### Context-Based Testing
Testing preferences via request context:
```go
func TestPreferencesHelperFunctions(t *testing.T) {
prefs := &Preferences{
CVLength: c.CVLengthLong,
CVIcons: c.CVIconsShow,
CVLanguage: c.LangSpanish,
CVTheme: c.CVThemeClean,
ColorTheme: c.ColorThemeDark,
}
req := httptest.NewRequest(http.MethodGet, "/", nil)
ctx := context.WithValue(req.Context(), PreferencesKey, prefs)
reqWithPrefs := req.WithContext(ctx)
t.Run("GetLanguage", func(t *testing.T) {
result := GetLanguage(reqWithPrefs)
if result != c.LangSpanish {
t.Errorf("GetLanguage() = %q, want %q", result, c.LangSpanish)
}
})
}
```
### Middleware Testing
Testing middleware chains:
```go
func TestContactRateLimiter_Middleware_Blocked(t *testing.T) {
rl := &ContactRateLimiter{
clients: make(map[string]*contactRateLimitEntry),
}
handler := http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
w.WriteHeader(http.StatusOK)
})
protected := rl.Middleware(handler)
// Exhaust the rate limit
limit := c.RateLimitContactRequests
for i := 0; i < limit; i++ {
req := httptest.NewRequest(http.MethodPost, "/api/contact", nil)
req.RemoteAddr = "192.168.1.1:12345"
rec := httptest.NewRecorder()
protected.ServeHTTP(rec, req)
}
// Next request should be blocked
req := httptest.NewRequest(http.MethodPost, "/api/contact", nil)
req.RemoteAddr = "192.168.1.1:12345"
rec := httptest.NewRecorder()
protected.ServeHTTP(rec, req)
if rec.Code != http.StatusTooManyRequests {
t.Errorf("Status = %d, want %d", rec.Code, http.StatusTooManyRequests)
}
}
```

## Coverage Gaps
### Why Some Packages Have 0% Coverage
#### `internal/pdf` (0%)
- **Reason**: Requires Chrome browser via chromedp
- **Solution**: Would need headless Chrome in CI/CD
- **Alternative**: Mock the chromedp interface (significant refactoring)
#### `internal/templates` (0%)
- **Reason**: File-system dependent template loading
- **Solution**: Could use embedded test templates
- **Impact**: Low priority - simple template wrapper
#### `internal/routes` (0%)
- **Reason**: Integration-level routing setup
- **Solution**: End-to-end testing with running server
- **Alternative**: Test individual handlers instead
#### `internal/models` (0%)
- **Reason**: Contains only interface definitions
- **Impact**: None - interfaces have no executable code
### Partial Coverage Explanations
#### `internal/middleware` (87.5%)
Uncovered code includes:
- Background goroutine cleanup functions (tickers)
- Production-only file logging (`/var/log/`)
- Edge cases in recovery middleware
#### `internal/email` (58.0%)
Uncovered code includes:
- Actual SMTP connection and sending
- TLS handshake code
- Network error handling
**Note**: Would require SMTP mock server
#### `internal/handlers` (62.9%)
Uncovered code includes:
- PDF generation handlers (need Chrome)
- Some HTMX-specific response paths
- Error paths for template loading failures
---
## Best Practices
### 1. Use Table-Driven Tests
```go
// Good: Table-driven
tests := []struct {
name string
input string
expected bool
}{
{"valid", "test@example.com", true},
{"invalid", "not-an-email", false},
}
for _, tt := range tests {
t.Run(tt.name, func(t *testing.T) {
// test code
})
}
```
### 2. Test Edge Cases
Always test:
- Empty inputs
- Maximum length inputs
- Unicode/UTF-8 characters
- Invalid parameters
- Boundary conditions
### 3. Use Descriptive Test Names
```go
// Good
t.Run("UTF-8 aware - valid Japanese characters", ...)
t.Run("Invalid - exceeds maximum length", ...)
// Bad
t.Run("test1", ...)
t.Run("case2", ...)
```
### 4. Isolate Tests
```go
// Good: Create fresh instance per test
func TestRateLimiter(t *testing.T) {
rl := &ContactRateLimiter{
clients: make(map[string]*contactRateLimitEntry),
}
// test code
}
```
### 5. Test Error Messages
```go
if !strings.Contains(body, "Too Many Requests") {
t.Error("Response should contain error message")
}
```
### 6. Use Constants from Production Code
```go
// Good: Use production constants
limit := c.RateLimitContactRequests
// Bad: Hardcode values
limit := 5
```
### 7. Check Response Headers
```go
contentType := rec.Header().Get(c.HeaderContentType)
if contentType != c.ContentTypeJSON {
t.Errorf("Content-Type = %q, want %q", contentType, c.ContentTypeJSON)
}
```

## CI/CD Integration
### GitHub Actions Example
```yaml

#!/bin/bash
# .git/hooks/pre-commit
echo "Running tests..."
go test ./internal/... -cover
if [ $? -ne 0 ]; then
echo "Tests failed. Commit aborted."
exit 1

## ADR-004: Application-Level Data Caching
**Status:** Accepted
**Date:** 2025-12-06
**Supersedes:** [ADR-001](#adr-001-no-data-caching)
### Context
As the CV site evolved to support multiple languages and increased usage, the original decision (ADR-001) to avoid caching was reconsidered. While the site traffic remains modest, the benefits of eliminating per-request file I/O became clear:
1. **Consistency**: Every request reads the same data
2. **Performance**: Eliminates disk I/O from hot paths
3. **Reliability**: Fail-fast at startup catches data errors early
4. **Simplicity**: No cache invalidation needed (data is static)
### Decision
**Implement application-level data caching with startup-time loading.**
The `internal/cache` package provides:
- `DataCache` struct holding CV and UI data for all supported languages
- Single load at application startup
- Thread-safe read access via `sync.RWMutex`
- Language-keyed retrieval (`GetCV(lang)`, `GetUI(lang)`)
### Implementation
```go
// At startup (main.go)
dataCache, err := cache.New([]string{"en", "es"})
if err != nil {
log.Fatalf("Failed to initialize data cache: %v", err)
}
// In handlers
cv := h.dataCache.GetCV(lang)
ui := h.dataCache.GetUI(lang)
```
### Rationale
1. **Zero Per-Request I/O**: Data loaded once, served from memory
2. **Fail-Fast**: All data issues caught at startup, not runtime
3. **Thread-Safe**: `sync.RWMutex` optimized for read-heavy workloads
4. **Minimal Complexity**: Simple map-based storage, no TTL/invalidation
5. **Testable**: 95.7% test coverage, including concurrency tests
### Consequences
- **Positive:**
- Faster request handling (no disk I/O)
- Earlier error detection (startup validation)
- Consistent data across requests
- Simple, well-tested implementation
- **Considerations:**
- Requires application restart to pick up data changes
- Memory usage increases slightly (minimal - ~KB per language)
- Deep copies required when handlers mutate data
