Documentation

Overview

Package autoscalingplansiface provides an interface to enable mocking the AWS Auto Scaling Plans service client for testing your code.

It is important to note that this interface will have breaking changes when the service model is updated and adds new API operations, paginators, and waiters.

Types

type ClientAPI

type ClientAPI interface {
	CreateScalingPlanRequest(*autoscalingplans.CreateScalingPlanInput) autoscalingplans.CreateScalingPlanRequest

	DeleteScalingPlanRequest(*autoscalingplans.DeleteScalingPlanInput) autoscalingplans.DeleteScalingPlanRequest

	DescribeScalingPlanResourcesRequest(*autoscalingplans.DescribeScalingPlanResourcesInput) autoscalingplans.DescribeScalingPlanResourcesRequest

	DescribeScalingPlansRequest(*autoscalingplans.DescribeScalingPlansInput) autoscalingplans.DescribeScalingPlansRequest

	GetScalingPlanResourceForecastDataRequest(*autoscalingplans.GetScalingPlanResourceForecastDataInput) autoscalingplans.GetScalingPlanResourceForecastDataRequest

	UpdateScalingPlanRequest(*autoscalingplans.UpdateScalingPlanInput) autoscalingplans.UpdateScalingPlanRequest
}

ClientAPI provides an interface to enable mocking the autoscalingplans.Client methods. This make unit testing your code that calls out to the SDK's service client's calls easier.

The best way to use this interface is so the SDK's service client's calls can be stubbed out for unit testing your code with the SDK without needing to inject custom request handlers into the SDK's request pipeline.

// myFunc uses an SDK service client to make a request to
// AWS Auto Scaling Plans.
func myFunc(svc autoscalingplansiface.ClientAPI) bool {
    // Make svc.CreateScalingPlan request
}

func main() {
    cfg, err := external.LoadDefaultAWSConfig()
    if err != nil {
        panic("failed to load config, " + err.Error())
    }

    svc := autoscalingplans.New(cfg)

    myFunc(svc)
}

In your _test.go file:

// Define a mock struct to be used in your unit tests of myFunc.
type mockClientClient struct {
    autoscalingplansiface.ClientPI
}
func (m *mockClientClient) CreateScalingPlan(input *autoscalingplans.CreateScalingPlanInput) (*autoscalingplans.CreateScalingPlanOutput, error) {
    // mock response/functionality
}

func TestMyFunc(t *testing.T) {
    // Setup Test
    mockSvc := &mockClientClient{}

    myfunc(mockSvc)

    // Verify myFunc's functionality
}

It is important to note that this interface will have breaking changes when the service model is updated and adds new API operations, paginators, and waiters. Its suggested to use the pattern above for testing, or using tooling to generate mocks to satisfy the interfaces.
