// Package epics_test contains tests that compile regardless of build tags. // This file verifies the no-op stub behaviour when the package is built without // the "epics" build tag (i.e. without CGo and EPICS Base). package epics_test import ( "testing" "github.com/uopi/uopi/internal/datasource/epics" ) // TestAvailable_NoopBuild verifies that Available() returns false when the // package is compiled without the "epics" build tag. // // When built WITH the tag the test still passes because Available() returns // true, which is a different (correct) state.
