In this page, i integrate GoConvey, sqlmock, go generate and GoMock to test golang code.
1. GoConvey
GoConvey is a yummy Go testing tool for gophers. Works with go test.
Features:
Directly integrates with
go testFully-automatic web UI (works with native Go tests, too)
Huge suite of regression tests
Shows test coverage (Go 1.2+)
Readable, colorized console output (understandable by any manager, IT or not)
Test code generator
Desktop notifications (optional)
Immediately open problem lines in Sublime Text (some assembly required)

// UnmarshalToMap unmarshal xml into map in util.go
func UnmarshalToMap(b []byte) map[string]interface{} {decoder := xml.NewDecoder(bytes.NewBuffer(b))s := NewStack()for {t, err := decoder.Token()if err != nil {if err == io.EOF {break}}
switch ele := t.(type) {case xml.StartElement:s.Push(ele)case xml.CharData:s.Push(string(xml.CharData(ele)))case xml.EndElement:entry := make(map[string]interface{})var val interface{}for {p := s.Pop()

}
return s.Pop().(map[string]interface{})
}// in util_test.go
func TestUnmarshalToMap(t *testing.T) {convey.Convey("Failed unmarshal xml to map", t, func() {b := []byte(`<?xml version="1.0"?><xml><appid><![CDATA[wxxxx]]></appid><case><cash_fee><![CDATA[1]]></cash_fee></case><mch_id><![CDATA[xxx]]></mch_id><nonce_str><![CDATA[KptCSXZh1qBjK8wb]]></nonce_str><out_refund_no_0><![CDATA[1519535580802]]></out_refund_no_0><out_trade_no><![CDATA[1515845954891]]></out_trade_no><refund><refund_account_0><![CDATA[REFUND_SOURCE_UNSETTLED_FUNDS]]></refund_account_0><refund_channel_0><![CDATA[ORIGINAL]]></refund_channel_0><refund_count>1</refund_count><refund_fee>1</refund_fee><other_refund><refund_fee_0>1</refund_fee_0><refund_id_0><![CDATA[50000405502018022503594217469]]></refund_id_0><refund_recv_accout_0><![CDATA[支付用户的零钱]]></refund_recv_accout_0><refund_status_0><![CDATA[SUCCESS]]></refund_status_0></other_refund><refund_success_time_0><![CDATA[2018-02-25 13:13:03]]></refund_success_time_0></refund><result_code><![CDATA[SUCCESS]]></result_code><return_code><![CDATA[SUCCESS]]></return_code><return_msg><![CDATA[OK]]></return_msg><sign><![CDATA[E8A30F02296C6169860A92C2D52AD5A8]]></sign><total_fee><![CDATA[1]]></total_fee><transaction_id><![CDATA[4200000100201801133414066940]]></transaction_id></xml>`)m := UnmarshalToMap(b)
convey.So(m["xml"].(map[string]interface{})["appid"], assertions.ShouldEqual, "wxxxx")convey.So((m["xml"].(map[string]interface{})["case"].(map[string]interface{}))["cash_fee"], assertions.ShouldEqual, "1")convey.So(((m["xml"].(map[string]interface{})["refund"].(map[string]interface{}))["other_refund"].(map[string]interface{}))["refund_fee_0"], assertions.ShouldEqual, "1")})
}2. Mock DB
sqlmock is a mock library implementing sql/driver. Which has one and only purpose - to simulate any sql driver behavior in tests, without needing a real database connection.
supports concurrency and multiple connections.
supports go1.8 Context related feature mocking and Named sql parameters.
does not require any modifications to your source code.
the driver allows to mock any sql driver method behavior.
has strict by default expectation order matching.
has no third party dependencies.
Install
go get github.com/DATA-DOG/go-sqlmockExample
func mockGormDB() (*gorm.DB, sqlmock.Sqlmock, error) {db, mock, err := sqlmock.New()if err != nil {return nil, nil, err}// GORMgormDB, err := gorm.Open("mysql", db) // Can be any connection stringif err != nil {return nil, nil, err}
gormDB.LogMode(true)
return gormDB, mock, nil
}
func TestMySQLChannelRepository_Get(t *testing.T) {Convey("Test ChannelRepository Get is failed!", t, func() {db, mock, err := mockGormDB()So(err, ShouldBeNil)defer db.Close()
now := time.Now()rows := sqlmock.NewRows([]string{"id", "chl_type", "chl_name", "chl_label", "chl_desc", "chl_logo", "state", "created_at", "created_by", "updated_at", "updated_by"}).AddRow(1, "wx_app", "微信App支付", "微信App支付", "微信 App 支付", "wx_app.png", 1, &now, "admin", &now, "admin")mock.ExpectQuery(regexp.QuoteMeta("SELECT * FROM `op_channel` WHERE (`op_channel`.`id` = 1)")).WillReturnRows(rows)
chlRepo := MySQLChannelRepository{GormRepository: gd.GormRepository{DB: db},}
var chl *model.OpChannelchl, err = chlRepo.Get(1)So(err, ShouldBeNil)So(chl.Id, ShouldEqual, 1)})
}3. Generating code
go generateis a command to generating code buildin golang release 1.4 and later.
Example
Add comments go:generate mockgen -destination mock_repo/mock_chl_repo.go github.com/cy18cn/octopus/mch/repository ChannelRepository for interface.
//go:generate mockgen -destination mock_repo/mock_chl_repo.go github.com/cy18cn/octopus/mch/repository ChannelRepository
type ChannelRepository interface {Get(id uint64) (*model.OpChannel, error)ListAll() ([]*model.OpChannel, error)
}Run command go generate to generate GoMock struct implement ChannelRepository in file mock_repo/mock_chl_repo.go.
// Code generated by MockGen. DO NOT EDIT.
// Source: github.com/cy18cn/octopus/mch/repository (interfaces: ChannelRepository)
// Package mock_repository is a generated GoMock package.
package mock_repository
import (model "github.com/cy18cn/octopus/mch/model"gomock "github.com/golang/mock/gomock"reflect "reflect"
)
// MockChannelRepository is a mock of ChannelRepository interface
type MockChannelRepository struct {ctrl *gomock.Controllerrecorder *MockChannelRepositoryMockRecorder
}
// MockChannelRepositoryMockRecorder is the mock recorder for MockChannelRepository
type MockChannelRepositoryMockRecorder struct {mock *MockChannelRepository
}
// NewMockChannelRepository creates a new mock instance
func NewMockChannelRepository(ctrl *gomock.Controller) *MockChannelRepository {mock := &MockChannelRepository{ctrl: ctrl}mock.recorder = &MockChannelRepositoryMockRecorder{mock}return mock
}
// EXPECT returns an object that allows the caller to indicate expected use
func (m *MockChannelRepository) EXPECT() *MockChannelRepositoryMockRecorder {return m.recorder
}
// Get mocks base method
func (m *MockChannelRepository) Get(arg0 uint64) (*model.OpChannel, error) {m.ctrl.T.Helper()ret := m.ctrl.Call(m, "Get", arg0)ret0, _ := ret[0].(*model.OpChannel)ret1, _ := ret[1].(error)return ret0, ret1
}
// Get indicates an expected call of Get
func (mr *MockChannelRepositoryMockRecorder) Get(arg0 interface{}) *gomock.Call {mr.mock.ctrl.T.Helper()return mr.mock.ctrl.RecordCallWithMethodType(mr.mock, "Get", reflect.TypeOf((*MockChannelRepository)(nil).Get), arg0)
}
// ListAll mocks base method
func (m *MockChannelRepository) ListAll() ([]*model.OpChannel, error) {m.ctrl.T.Helper()ret := m.ctrl.Call(m, "ListAll")ret0, _ := ret[0].([]*model.OpChannel)ret1, _ := ret[1].(error)return ret0, ret1
}
// ListAll indicates an expected call of ListAll
func (mr *MockChannelRepositoryMockRecorder) ListAll() *gomock.Call {mr.mock.ctrl.T.Helper()return mr.mock.ctrl.RecordCallWithMethodType(mr.mock, "ListAll", reflect.TypeOf((*MockChannelRepository)(nil).ListAll))
}4. GoMock
GoMock is a mocking framework for the Go programming language. It integrates well with Go's built-in testing package, but can be used in other contexts too.
Installation
go get github.com/golang/mock/mockgenExample
var (chls = []*model.OpChannel{{Id: 1,ChlType: "wx_app",ChlName: "微信App支付",ChlLabel: "微信App支付",ChlDesc: "微信 App 支付",ChlLogo: "wx_app.png",State: 1,},{Id: 2,ChlType: "wx_jsapi",ChlName: "微信jsapi支付",ChlLabel: "微信jsapi支付",ChlDesc: "微信 jsapi 支付",ChlLogo: "wx_jsapi.png",State: 1,},{Id: 3,ChlType: "wx_mini",ChlName: "微信mini支付",ChlLabel: "微信mini支付",ChlDesc: "微信 mini 支付",ChlLogo: "wx_mini.png",State: 1,},}
pChls = []*model.OpPayChannel{{Id: 1,AppId: "134567",ChlId: 1,PayConfig: "",State: 1,},{Id: 2,AppId: "134567",ChlId: 2,PayConfig: "",State: 1,},}
app = &model.OpMchApp{Id: 1,MchId: "123456",MchName: "测试",AppName: "测试",Appid: "134567",MchKey: "15234212d4sa4df523s4af",State: 1,}
)
func TestPayChlService_pChannelList(t *testing.T) {Convey("", t, func() {ctrl := gomock.NewController(t)chlRepo := mock_repository.NewMockChannelRepository(ctrl)payChlRepo := mock_repository.NewMockPayChlRepository(ctrl)mchAppRepo := mock_repository.NewMockMchAppRepository(ctrl)
chlRepo.EXPECT().ListAll().Return(chls, nil)payChlRepo.EXPECT().FindByAppId("134567").Return(pChls, nil)
pService := &PayChlService{channelRepo: chlRepo,payChlRepo: payChlRepo,mchAppRepo: mchAppRepo,}
resp, err := pService.pChannelList("134567")So(err, ShouldBeNil)So(len(resp), ShouldEqual, 3)So(resp[2].State, ShouldEqual, 0)})
