// Package mock provides a system by which it is possible to mock your objects
|
||
|
|
// and verify calls are happening as expected.
|
||
|
|
//
|
||
|
|
// Example Usage
|
||
|
|
//
|
||
|
|
// The mock package provides an object, Mock, that tracks activity on another object. It is usually
|
||
|
|
// embedded into a test object as shown below:
|
||
|
|
//
|
||
|
|
// type MyTestObject struct {
|
||
|
|
// // add a Mock object instance
|
||
|
|
// mock.Mock
|
||
|
|
//
|
||
|
|
// // other fields go here as normal
|
||
|
|
// }
|
||
|
|
//
|
||
|
|
// When implementing the methods of an interface, you wire your functions up
|
||
|
|
// to call the Mock.Called(args...) method, and return the appropriate values.
|
||
|
|
//
|
||
|
|
// For example, to mock a method that saves the name and age of a person and returns
|
||
|
|
// the year of their birth or an error, you might write this:
|
||
|
|
//
|
||
|
|
// func (o *MyTestObject) SavePersonDetails(firstname, lastname string, age int) (int, error) {
|
||
|
|
// args := o.Called(firstname, lastname, age)
|
||
|
|
// return args.Int(0), args.Error(1)
|
||
|
|
// }
|
||
|
|
//
|
||
|
|
// The Int, Error and Bool methods are examples of strongly typed getters that take the argument
|
||
|
|
// index position. Given this argument list:
|
||
|
|
//
|
||
|
|
// (12, true, "Something")
|
||
|
|
//
|
||
|
|
// You could read them out strongly typed like this:
|
||
|
|
//
|
||
|
|
// args.Int(0)
|
||
|
|
// args.Bool(1)
|
||
|
|
// args.String(2)
|
||
|
|
//
|
||
|
|
// For objects of your own type, use the generic Arguments.Get(index) method and make a type assertion:
|
||
|
|
//
|
||
|
|
// return args.Get(0).(*MyObject), args.Get(1).(*AnotherObjectOfMine)
|
||
|
|
//
|
||
|
|
// This may cause a panic if the object you are getting is nil (the type assertion will fail), in those
|
||
|
|
// cases you should check for nil first.
