// Package gomock is a mock framework for Go.
|
|
//
|
|
// Standard usage:
|
|
//
|
|
// (1) Define an interface that you wish to mock.
|
|
// type MyInterface interface {
|
|
// SomeMethod(x int64, y string)
|
|
// }
|
|
// (2) Use mockgen to generate a mock from the interface.
|
|
// (3) Use the mock in a test:
|
|
// func TestMyThing(t *testing.T) {
|
|
// mockCtrl := gomock.NewController(t)
|
|
// mockObj := something.NewMockMyInterface(mockCtrl)
|
|
// mockObj.EXPECT().SomeMethod(4, "blah")
|
|
// // pass mockObj to a real object and play with it.
|
|
// }
|
|
//
|
|
// By default, expected calls are not enforced to run in any particular order.
|
|
// Call order dependency can be enforced by use of InOrder and/or Call.After.
|
|
// Call.After can create more varied call order dependencies, but InOrder is
|
|
// often more convenient.
|
|
//
|
|
// The following examples create equivalent call order dependencies.
|
|
//
|
|
// Example of using Call.After to chain expected call order:
|
|
//
|
|
// firstCall := mockObj.EXPECT().SomeMethod(1, "first")
|
|
// secondCall := mockObj.EXPECT().SomeMethod(2, "second").After(firstCall)
|
|
// mockObj.EXPECT().SomeMethod(3, "third").After(secondCall)
|
|
//
|
|
// Example of using InOrder to declare expected call order:
|
|
//
|
|
// gomock.InOrder(
|
|
// mockObj.EXPECT().SomeMethod(1, "first"),
|
|
// mockObj.EXPECT().SomeMethod(2, "second"),
|
|
// mockObj.EXPECT().SomeMethod(3, "third"),
|
|
// )
|
|
//
|
|
// The standard TestReporter most users will pass to `NewController` is a
|
|
// `*testing.T` from the context of the test. Note that this will use the
|
|
// standard `t.Error` and `t.Fatal` methods to report what happened in the test.
|
|
// In some cases this can leave your testing package in a weird state if global
|
|
// state is used since `t.Fatal` is like calling panic in the middle of a
|
|
// function. In these cases it is recommended that you pass in your own
|
|
// `TestReporter`.
