测试用例

在原来的v1.6.7分支上，修改个测试用例，新增个测试用例

nacos_client_test.go

测试用例一：TestNacosClient_getAllServiceNames

预期结果：获取Nacos服务端里注册的所有服务名并存入AllDoms

实际结果：成功获取Nacos服务端里注册的所有服务名并存入AllDoms

func TestNacosClient_getAllServiceNames(t *testing.T) {
	GrpcClient = grpcClientTest
	nacosClientTest.getAllServiceNames()

	AllDoms.DLock.Lock()
	defer AllDoms.DLock.Unlock()
	doms := GrpcClient.GetAllServicesInfo()

	for _, dom := range doms {
		assert.True(t, AllDoms.Data[dom])
	}
	if len(doms) == len(AllDoms.Data) {
		t.Log("Get all serviceName from servers passed")
	} else {
		t.Error("Get all serviceName from servers error")
	}
}

测试用例二：TestNacosClient_getDomNow

预期结果：获取Nacos服务端里某个服务的具体信息并存入缓存中

实际结果：成功获取Nacos服务端里某个服务的具体信息并存入缓存中

func TestNacosClient_getServiceNow(t *testing.T) {
	GrpcClient = grpcClientTest
	nacosClientTest.getAllServiceNames()
	testServiceMap := NewConcurrentMap()

	for serviceName, _ := range AllDoms.Data {
		nacosClientTest.getServiceNow(serviceName, &nacosClientTest.serviceMap, "0.0.0.0")
	}

	for serviceName, _ := range AllDoms.Data {
		testService := GrpcClient.GetService(serviceName)
		testServiceMap.Set(serviceName, testService)
		s, ok := nacosClientTest.GetDomainCache().Get(serviceName)
		assert.True(t, ok)
		service := s.(model.Service)
		assert.True(t, len(service.Hosts) == len(testService.Hosts))
	}

	if len(nacosClientTest.GetDomainCache()) == len(testServiceMap) {
		t.Log("Get all servicesInfo from servers passed")
	} else {
		t.Error("Get all servicesInfo from servers error")
	}
}

nacos_grpc_client_test.go

测试用例三：TestGetAllServicesInfo

预期结果：gRPC请求获取Nacos服务端里注册的所有服务名

func TestGetAllServicesInfo(t *testing.T) {
	services := grpcClientTest.GetAllServicesInfo()
	if len(services) > 0 {
		t.Log("GrpcClient get all servicesInfo passed")
	} else {
		t.Log("GrpcClient get all servicesInfo empty")
	}
}

测试用例四：TestGetService

	doms := grpcClientTest.GetAllServicesInfo()
	for _, dom := range doms {
		err := grpcClientTest.Subscribe(dom)
		if err != nil {
			t.Error("GrpcClient subscribe service error")
			return
		}
	}
	t.Log("GrpcClient subscribe service passed")
}

测试用例六：TestCallback

预期结果：当Nacos服务端服务发生改变时，通过回调函数更新客户端的服务数据

实际结果：当Nacos服务端服务发生改变时，成功通过回调函数更新客户端的服务数据

func TestCallback(t *testing.T) {
    services := model.Service{
            ......
        }
    
    grpcClientTest.nacosClient.GetDomainCache().Set("demo.go", services)

    newServices := model.Service{
            ······
        }

    grpcClientTest.Callback(newServices.Hosts, nil)

	s, _ := grpcClientTest.nacosClient.GetDomainCache().Get("demo.go")

	updateServices := s.(model.Service)

	if len(newServices.Hosts) == len(updateServices.Hosts) {
		t.Log("GrpcClient Service SubscribeCallback passed")
