### Question:
ProcessVariableReader { public static String getProcessVariableName(Property p) { String name = p.getName(); return name == null || name.isEmpty() ? p.getId() : name; }  static String getProcessVariableName(Property p); static boolean isProcessVariable(Property p);  }### Answer:
@Test public void getProcessVariableName() { assertEquals("PV1", ProcessVariableReader.getProcessVariableName(property1)); assertEquals("PV2", ProcessVariableReader.getProcessVariableName(property2)); assertEquals("PV3", ProcessVariableReader.getProcessVariableName(property3)); assertEquals("caseFile_CV4", ProcessVariableReader.getProcessVariableName(property4)); assertEquals("caseFile_CV5", ProcessVariableReader.getProcessVariableName(property5)); }
