The embodiments herein relate to a method performed by a testing device for enabling testing of a communication node. The testing device measures a test parameter associated with RF characteristics of the communication node when it is located at a test location during a first condition. The communication node is configured with a node setting during the measurement in the first condition. The testing device measures the test parameter associated with the RF characteristics of the communication node when it is located at the test location during a second condition. The communication node is configured with the same node setting in the second condition as in the first condition. The testing device checks whether a result parameter associated with the test parameter measured during the first and second condition fulfills a requirement.
