+### Metric Transformation
+
+Enable transformation of old metric names to new format for testing against locally built instances:
+
+```bash
+export CYPRESS_MOCK_NEW_METRICS=true
+```
+
+When enabled, `cy.transformMetrics()` will intercept Prometheus queries and transform both request and response:
+- **Request**: `cluster:health:components:map` → `cluster_health_components_map` 
+- **Response**: `cluster:health:components:map` → `cluster_health_components_map`
+
+**Usage:**
+```typescript
+// Call before visiting pages that make Prometheus queries
+cy.transformMetrics();
+cy.visit('/monitoring/incidents');
+```
+
+**Use Cases:**
+- **`CYPRESS_MOCK_NEW_METRICS=false`** (default): Test against current release/backend
+- **`CYPRESS_MOCK_NEW_METRICS=true`**: Test against locally built instances with new metric format
+
+Default: `false` (if `CYPRESS_MOCK_NEW_METRICS` is not set)
