The objective of testing is to determine whether an implementation under test conforms to its specification. In distributed test architectures involving multiple testers, this objective can be complicated by the fact that testers may encounter problems relating to controllability and observability during the application of tests. The controllability problem manifests itself when a tester is required to send the current input and because it did not send the previous input nor did it receive the previous output it cannot determine when to send the input. The observability problem manifests itself when a tester is expecting an output in response to either the previous input or the current input and because it is not the sender of the current input, it cannot determine when to start and stop waiting for the output. Based on a distinguishing sequence, a checking sequence construction method is proposed to yield a sequence that is free from controllability and observability problems.
