+### Testing
+
+To ensure the correct implementation and usage of RKP VM markers, we've
+incorporated comprehensive checks into various xTS tests (e.g.,
+`VtsHalRemotelyProvisionedComponentTargetTest`).
+
+These tests validate the following conditions:
+
+- The RKP VM DICE chain must have a continuous presence of at least two RKP VM
+  markers, extending to the leaf DICE certificate.
+- Non-RKP VM DICE chains must not have a continuous presence of two or more RKP
+  VM markers, preventing non-RKP VM chains from being incorrectly identified as
+  RKP VM chains.
