1 为函数打桩
ApplyFunc 第一个参数是函数名第二个参数是桩函数。测试完成后patches 对象通过 Reset 成员方法删除所有测试桩。
package testimport (./fakeencoding/json. github.com/agiledragon/gomonkey. github.com/smartystreets/goconvey/conveytesting
)var (outputExpect xxx-vethName100-yyy
)func TestApplyFunc(t *testing.T) {Convey(TestApplyFunc, t, func() {Convey(one func for succ, func() {patches : ApplyFunc(fake.Exec, func(_ string, _ ...string) (string, error) {return outputExpect, nil})defer patches.Reset()output, err : fake.Exec(, )So(err, ShouldEqual, nil)So(output, ShouldEqual, outputExpect)})Convey(one func for fail, func() {patches : ApplyFunc(fake.Exec, func(_ string, _ ...string) (string, error) {return , fake.ErrActual})defer patches.Reset()output, err : fake.Exec(, )So(err, ShouldEqual, fake.ErrActual)So(output, ShouldEqual, )})Convey(two funcs, func() {patches : ApplyFunc(fake.Exec, func(_ string, _ ...string) (string, error) {return outputExpect, nil})defer patches.Reset()patches.ApplyFunc(fake.Belong, func(_ string, _ []string) bool {return true})output, err : fake.Exec(, )So(err, ShouldEqual, nil)So(output, ShouldEqual, outputExpect)flag : fake.Belong(, nil)So(flag, ShouldBeTrue)})Convey(input and output param, func() {patches : ApplyFunc(json.Unmarshal, func(data []byte, v interface{}) error {if data nil {panic(input param is nil!)}p : v.(*map[int]int)*p make(map[int]int)(*p)[1] 2(*p)[2] 4return nil})defer patches.Reset()var m map[int]interr : json.Unmarshal([]byte(123), m)So(err, ShouldEqual, nil)So(m[1], ShouldEqual, 2)So(m[2], ShouldEqual, 4)})})
}这边是对fake.exec函数打桩模拟exec函数的输出。,fake.exec函数在fake目录下可以来下我的代码库看下。 上面这种模拟函数输出有啥应用从我实际使用的角度出发我们看下面例子 mytest.go
package mytestfunc AddOne(t int32) int32 {return t1
}func MinusOne(t int32) int32 {return t-1
}func MultiAddOne(t int32) int32 {t MinusOne(t)t AddOne(t)t AddOne(t)return t
}测试类mytest_test.go
package mytestimport (. github.com/agiledragon/gomonkey. github.com/smartystreets/goconvey/conveytesting
)func TestMultiAddOne(t *testing.T) {Convey(TestApplyFunc, t, func() {Convey(input and output param, func() {patches : ApplyFunc(AddOne, func(t1 int32) int32 {return 0})//对函数AddOne打桩defer patches.Reset()patches.ApplyFunc(MinusOne, func(t1 int32) int32 {return -1})//对函数MinusOne打桩result : MultiAddOne(10) //看好了我调用的是MultiAddOne函数而MultiAddOne函数内部调用了AddOne和MinusOne。So(result, ShouldEqual, 0)})})
}
我模拟了AddOne和MinusOne函数的输出以达到MultiAddOne函数的效果。
2 函数打序列桩
ApplyFuncSeq第一个参数是函数名第二个参数是特定的桩序列参数。测试完成后patches 对象通过 Reset 成员方法删除所有测试桩。
package testimport (. github.com/agiledragon/gomonkeygithub.com/agiledragon/gomonkey/test/fake. github.com/smartystreets/goconvey/conveytesting

package testimport (. github.com/agiledragon/gomonkeygithub.com/agiledragon/gomonkey/test/fake. github.com/smartystreets/goconvey/conveytesting
)func TestApplyFuncVar(t *testing.T) {Convey(TestApplyFuncVar, t, func() {Convey(for succ, func() {str : hellopatches : ApplyFuncVar(fake.Marshal, func (_ interface{}) ([]byte, error) {return []byte(str), nil})// fake.Marshal是函数变量defer patches.Reset()bytes, err : fake.Marshal(nil)So(err, ShouldEqual, nil)So(string(bytes), ShouldEqual, str)})Convey(for fail, func() {patches : ApplyFuncVar(fake.Marshal, func (_ interface{}) ([]byte, error) {return nil, fake.ErrActual})defer patches.Reset()_, err : fake.Marshal(nil)So(err, ShouldEqual, fake.ErrActual)})})

)func TestApplyMethod(t *testing.T) {slice : fake.NewSlice()var s *fake.SliceConvey(TestApplyMethod, t, func() {Convey(for succ, func() {err : slice.Add(1)So(err, ShouldEqual, nil)patches : ApplyMethod(reflect.TypeOf(s), Add, func(_ *fake.Slice, _ int) error {return nil})defer patches.Reset()err slice.Add(1)So(err, ShouldEqual, nil)err slice.Remove(1)So(err, ShouldEqual, nil)So(len(slice), ShouldEqual, 0)})Convey(for already exist, func() {err : slice.Add(2)So(err, ShouldEqual, nil)patches : ApplyMethod(reflect.TypeOf(s), Add, func(_ *fake.Slice, _ int) error {return fake.ErrElemExsit})defer patches.Reset()err slice.Add(1)So(err, ShouldEqual, fake.ErrElemExsit)err slice.Remove(2)So(err, ShouldEqual, nil)So(len(slice), ShouldEqual, 0)})Convey(two methods, func() {err : slice.Add(3)So(err, ShouldEqual, nil)defer slice.Remove(3)patches : ApplyMethod(reflect.TypeOf(s), Add, func(_ *fake.Slice, _ int) error {return fake.ErrElemExsit})defer patches.Reset()patches.ApplyMethod(reflect.TypeOf(s), Remove, func(_ *fake.Slice, _ int) error {return fake.ErrElemNotExsit})err slice.Add(2)So(err, ShouldEqual, fake.ErrElemExsit)err slice.Remove(1)So(err, ShouldEqual, fake.ErrElemNotExsit)So(len(slice), ShouldEqual, 1)So(slice[0], ShouldEqual, 3)})Convey(one func and one method, func() {err : slice.Add(4)So(err, ShouldEqual, nil)defer slice.Remove(4)patches : ApplyFunc(fake.Exec, func(_ string, _ ...string) (string, error) {return outputExpect, nil})defer patches.Reset()patches.ApplyMethod(reflect.TypeOf(s), Remove, func(_ *fake.Slice, _ int) error {return fake.ErrElemNotExsit})output, err : fake.Exec(, )So(err, ShouldEqual, nil)So(output, ShouldEqual, outputExpect)err slice.Remove(1)So(err, ShouldEqual, fake.ErrElemNotExsit)So(len(slice), ShouldEqual, 1)So(slice[0], ShouldEqual, 4)})})
}7、成员方法打序列桩

)func TestApplyInterfaceReused(t *testing.T) {e : fake.Etcd{}Convey(TestApplyInterfaceReused, t, func() {patches : ApplyFunc(fake.NewDb, func(_ string) fake.Db {return e})defer patches.Reset()db : fake.NewDb(mysql)Convey(TestApplyInterface, func() {info : hello interfacepatches.ApplyMethod(reflect.TypeOf(e), Retrieve,func(_ *fake.Etcd, _ string) (string, error) {return info, nil})output, err : db.Retrieve()So(err, ShouldEqual, nil)So(output, ShouldEqual, info)})Convey(TestApplyInterfaceSeq, func() {info1 : hello cppinfo2 : hello golanginfo3 : hello gomonkeyoutputs : []OutputCell{{Values: Params{info1, nil}},{Values: Params{info2, nil}},{Values: Params{info3, nil}},}patches.ApplyMethodSeq(reflect.TypeOf(e), Retrieve, outputs)output, err : db.Retrieve()So(err, ShouldEqual, nil)So(output, ShouldEqual, info1)output, err db.Retrieve()So(err, ShouldEqual, nil)So(output, ShouldEqual, info2)output, err db.Retrieve()So(err, ShouldEqual, nil)So(output, ShouldEqual, info3)})})
}总结
在我看来gomonkey是弥补了goconvey的不足两者一起使用可以满足基本需要。goconvey负责断言gomonkey负责为变量和函数打桩构造各种测试条件。
