Error with go mock when using constants

Getting Help
1

Hi,

I have a function which takes a struct as argument. This struct contains int64 variables.

I have used go mock for mocking unitest cases.

But the problem is when I pass int64 variables it says Got and Want are different at function level.(In arguments).

Running tool: /usr/local/go/bin/go test -timeout 30s -run ^Test_queryResolver_SellersByStatus$ query/gty_qry_bo/graph

But test cases are passed when I add fmt.Println(arg1) in Recorder function.
Does fmt.Println does any thing?

If I change the param type of arg1 to my struct type from interface{}

It works fine.

But How it works if I just add fmt.Println() without changing the param type?

It is good to change the DO NOT EDIT file to fix this issue?

Thanks,

Can you share an example of the actual code? I can’t think of any reason off the top of my head how any of the fmt.Print “family” of functions would change any of their parameters, but if you show your code, we can provide more information.

Actual Function:-

// GetSellersByStatus indicates an expected call of GetSellersByStatus.
func (mr *MockBoQueryClientMockRecorder) GetSellersByStatus(arg0,arg1 interface{}, arg2 ...interface{}) *gomock.Call {
	mr.mock.ctrl.T.Helper()
	varargs := append([]interface{}{arg0, arg1}, arg2...)
	return mr.mock.ctrl.RecordCallWithMethodType(mr.mock, "GetSellersByStatus", reflect.TypeOf((*MockBoQueryClient)(nil).GetSellersByStatus), varargs...)
}

It worked if I change the param type or add add print in that without Param.
Modified Function : -

// GetSellersByStatus indicates an expected call of GetSellersByStatus.
func (mr *MockBoQueryClientMockRecorder) GetSellersByStatus(arg0 interface{}, arg1 *generated.SellersByStatusRequest, arg2 ...interface{}) *gomock.Call {
	mr.mock.ctrl.T.Helper()
//fmt.Println(arg1)
	varargs := append([]interface{}{arg0, arg1}, arg2...)
	return mr.mock.ctrl.RecordCallWithMethodType(mr.mock, "GetSellersByStatus", reflect.TypeOf((*MockBoQueryClient)(nil).GetSellersByStatus), varargs...)
}

Sorry for the late reply
