Test Architecture

Mock Server Approach

All tests use httptest.NewServer to create mock ONVIF device servers that return properly formatted SOAP/XML responses. This approach:

1. No External Dependencies - Tests run completely standalone
2. Fast Execution - All tests complete in ~35 seconds total
3. Deterministic Results - No network flakiness or real device dependencies
4. Full Control - Can test error cases, edge cases, and specific responses

Test Structure

Each test follows this pattern:

func TestAPIName(t *testing.T) {
    // 1. Create mock server with SOAP XML response
    server := httptest.NewServer(http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
        // Return valid ONVIF SOAP response
    }))
    defer server.Close()

    // 2. Create client pointing to mock server
    client, err := NewClient(server.URL)
    if err != nil {
        t.Fatalf("Failed to create client: %v", err)
    }

    // 3. Call API under test
    result, err := client.APIMethod(context.Background(), params...)
    if err != nil {
        t.Fatalf("API call failed: %v", err)
    }

    // 4. Validate response
    if result.Field != "expected" {
        t.Errorf("Expected 'expected', got %s", result.Field)
    }
}
