TEST_F(ModelObject, CanAccessVariableByBrowsePath)
{
  OpcUa::Model::Server server(Services);
  OpcUa::Model::Object serverObject = server.GetObject(OpcUa::ObjectId::Server);
  OpcUa::RelativePath path;
  path.Elements.push_back(GetHierarchicalElement(OpcUa::Names::ServerStatus));

  OpcUa::Model::Variable buildNumber = serverObject.GetVariable(path);
  EXPECT_EQ(buildNumber.GetBrowseName(), OpcUa::QualifiedName(OpcUa::Names::BuildNumber));
}

Beispiel #2

Datei: model_object_ut.cpp Projekt: AlexejStukov/freeopcua

TEST_F(ModelObject, ObjectCanCreateVariable)
{
  OpcUa::Model::Server server(Services);
  OpcUa::Model::Object rootObject = server.RootObject();
  OpcUa::QualifiedName name("new_variable");
  OpcUa::Variant value = 8;
  OpcUa::Model::Variable variable = rootObject.CreateVariable(name, value);

  ASSERT_NE(variable.GetId(), OpcUa::ObjectId::Null);
  ASSERT_EQ(variable.GetBrowseName(), name);
  ASSERT_EQ(variable.GetDisplayName(), OpcUa::LocalizedText(name.Name));
  ASSERT_EQ(variable.GetValue(), value);
}
