+## Updating the existing call tracer test cases
+In case a change is introduced to the output/format of the call tracer, you may use the following invocation to update the expected output with the current output:
+```bash
+UPDATE_TESTS=1 go test ./eth/tracers/internal/tracetest
+```
+
+This will blindly "accept" the current trace response as the correct one, so manual inspection of the updated outputs is advised to ensure they are as expected.
