The present document provides how to optimally set up the test environment to execute test case implementations based on ETSI TC SCP test specifications. This includes (but is not limited to): Derived guidelines to set up a test environment; Test equipment behaviour in case of additional activity triggered by test sequences; Optimization of the test environment; - Noise issues when using the Single Wire Protocol; - Limiting the noise impacts; Checking the integrity of the test environment; Example of a Test Case for Integrity check. The targeted audience for the present document is users of test case implementations based on ETSI TC SCP test specifications as well as test equipment manufacture.
