Unit testing 戈朗模拟情境恐慌
所以我在golang使用和进行单元测试 测试代码如下所示:Unit testing 戈朗模拟情境恐慌,unit-testing,go,mockery,testify,Unit Testing,Go,Mockery,Testify,所以我在golang使用和进行单元测试 测试代码如下所示: const bufSize = 1024 * 1024 var lis *bufconn.Listener var mockAccountService = &mocks.AccountService{} func init() { lis = bufconn.Listen(bufSize) s := grpc.NewServer() RegisterAccountManagementHandler
const bufSize = 1024 * 1024
var lis *bufconn.Listener
var mockAccountService = &mocks.AccountService{}
func init() {
lis = bufconn.Listen(bufSize)
s := grpc.NewServer()
RegisterAccountManagementHandlerServer(s, &server{mockAccountService})
go func() {
if err := s.Serve(lis); err != nil {
log.Fatalf("Server exited with error: %v", err)
}
}()
}
func bufDialer(context.Context, string) (net.Conn, error) {
return lis.Dial()
}
func TestSayHello(t *testing.T) {
var a uint64 = 1
ctx := context.Background()
conn, err := grpc.DialContext(ctx, "bufnet", grpc.WithContextDialer(bufDialer), grpc.WithInsecure())
if err != nil {
t.Fatalf("Failed to dial bufnet: %v", err)
}
defer conn.Close()
client := NewAccountManagementHandlerClient(conn)
mockAccountService.On("GetSavingAccount", context.Background(), a, a, "Hello", 1).Return(&models.SavingAccount{
CustomerID: 1,
ID: 1,
CardNo: "Hello",
SavingProductID: 1,
Balance: 0,
Status: 1,
})
resp, err := client.GetSavingAccount(ctx, &GetSavingAccountDataRequest{
Id: 1,
CustomerId: 1,
CardNo: "Hello",
SavingProductId: 1,
})
if err != nil {
t.Fatalf("SayHello failed: %v", err)
}
fmt.Printf("Response: %+v", resp)
// Test for output here.
但我得到的错误如下:
const bufSize = 1024 * 1024
var lis *bufconn.Listener
var mockAccountService = &mocks.AccountService{}
func init() {
lis = bufconn.Listen(bufSize)
s := grpc.NewServer()
RegisterAccountManagementHandlerServer(s, &server{mockAccountService})
go func() {
if err := s.Serve(lis); err != nil {
log.Fatalf("Server exited with error: %v", err)
}
}()
}
func bufDialer(context.Context, string) (net.Conn, error) {
return lis.Dial()
}
func TestSayHello(t *testing.T) {
var a uint64 = 1
ctx := context.Background()
conn, err := grpc.DialContext(ctx, "bufnet", grpc.WithContextDialer(bufDialer), grpc.WithInsecure())
if err != nil {
t.Fatalf("Failed to dial bufnet: %v", err)
}
defer conn.Close()
client := NewAccountManagementHandlerClient(conn)
mockAccountService.On("GetSavingAccount", context.Background(), a, a, "Hello", 1).Return(&models.SavingAccount{
CustomerID: 1,
ID: 1,
CardNo: "Hello",
SavingProductID: 1,
Balance: 0,
Status: 1,
})
resp, err := client.GetSavingAccount(ctx, &GetSavingAccountDataRequest{
Id: 1,
CustomerId: 1,
CardNo: "Hello",
SavingProductId: 1,
})
if err != nil {
t.Fatalf("SayHello failed: %v", err)
}
fmt.Printf("Response: %+v", resp)
// Test for output here.
我应该向mock context.Background传递什么值
我试过mock.AnythingOfType&context.emptyCtx,mock.AnythingOfType&context.emptyCtx,mock
多谢各位
编辑:
我试过了
mockAccountService.On("GetSavingAccount", context.Background(), a, a, "Hello", 1).Return(...})
并获得:
GetSavingAccount(*context.valueCtx,uint64,uint64,string,int64)
0: &context.valueCtx{Context:(*context.valueCtx)(0xc000021290), key:grpc.streamKey{}, val:(*transport.Stream)(0xc000522100)}
...
The closest call I have is:
GetSavingAccount(*context.emptyCtx,uint64,uint64,string,int)
0: (*context.emptyCtx)(0xc00002a080)
...
GetSavingAccount方法的方法定义为:
func a*accountService GetSavingAccountctx context.context,customerID,id uint64,cardNo string,savingProductId int64*models.SavingAccount,error因此,您有一个方法:
GetSavingAccount(*context.Context,uint64,uint64,string,int64)
你嘲笑我:
GetSavingAccount(*context.Context,uint64,uint64,string,int)
最后一个参数存在差异,您的问题是int64和int,因此您需要:
mockAccountService.On("GetSavingAccount", mock.Anything, a, a, "Hello", int64(1)).Return(...})
对于上下文参数,始终使用mock.Anything,这比模拟上下文更容易。注意int/int64/int32和其他类型,也要注意指针/结构参数。因此,您有以下方法:
GetSavingAccount(*context.Context,uint64,uint64,string,int64)
你嘲笑我:
GetSavingAccount(*context.Context,uint64,uint64,string,int)
