Functions

func CreateAWSError

func CreateAWSError(awsError ServiceAPIError) awserr.RequestFailure

CreateAWSError is used for mocking the types of errors received from aws-sdk-go so that the expected code path executes. Support for specifying the HTTP status code and request ID can be added in the future if needed

func IsYamlEqual

func IsYamlEqual(expectation *string, actualYamlByteArray *[]byte) bool

Checks to see if the contents of a given yaml file, with name stored in expectation, matches the given actualYamlByteArray.

func LoadFromFixture

func LoadFromFixture(
	fixturePath string,
	output interface{},
)

LoadFromFixture fills an empty pointer variable with the data from a fixture JSON/YAML file.

Types

type Expect

type Expect struct {
	LatestState string `json:"latest_state"`
	// Error is a string matching the message of the expected error returned from the ResourceManager operation.
	// Possible errors can be found in runtime/pkg/errors/error.go
	Error string `json:"error"`
}

Expect represents test scenario expected outcome fixture to load from file path

type Fixture

type Fixture struct {
	// DesiredState lets you specify fixture path to load the desired state fixture
	DesiredState string `json:"desired_state"`
	// LatestState lets you specify fixture path to load the current state fixture
	LatestState string `json:"latest_state"`
	// ServiceAPIs lets you specify fixture path to mock service sdk api response
	ServiceAPIs []ServiceAPI `json:"svc_api"`
}

Fixture represents test scenario fixture to load from file paths

type ServiceAPI

type ServiceAPI struct {
	Operation       string           `json:"operation"`
	Output          string           `json:"output_fixture,omitempty"`
	ServiceAPIError *ServiceAPIError `json:"error,omitempty"`
}

ServiceAPI represents details about the the service sdk api and fixture path to mock its response

type ServiceAPIError

type ServiceAPIError struct {
	// Code here is usually the type of fault/error, not the HTTP status code
	Code    string `json:"code"`
	Message string `json:"message"`
}

ServiceAPIError contains the specification for the error of the mock API response

type TestConfig

type TestConfig struct {
	Name        string         `json:"name"`
	Description string         `json:"description"`
	Scenarios   []TestScenario `json:"scenarios"`
}

TestConfig represents declarative unit test

type TestRunnerDelegate

type TestRunnerDelegate interface {
	ResourceDescriptor() acktypes.AWSResourceDescriptor
	Equal(desired acktypes.AWSResource, latest acktypes.AWSResource) bool // remove it when ResourceDescriptor.Delta() is available
	YamlEqual(expected string, actual acktypes.AWSResource) bool          // new
	ResourceManager(*mocksvcsdkapi.SageMakerAPI) acktypes.AWSResourceManager
	EmptyServiceAPIOutput(apiName string) (interface{}, error)
	GoTestRunner() *testing.T
}

TestRunnerDelegate provides interface for custom resource tests to implement. TestSuiteRunner depends on it to run tests for custom resource.

type TestScenario

type TestScenario struct {
	Name        string `json:"name"`
	Description string `json:"description"`
	// Fixture lets you specify test scenario given input fixtures
	Fixture Fixture `json:"given"`
	// UnitUnderTest lets you specify the unit to test
	// For example resource manager API: ReadOne, Create, Update, Delete
	UnitUnderTest string `json:"invoke"`
	// Expect lets you specify test scenario expected outcome fixtures
	Expect Expect `json:"expect"`
}

TestScenario represents declarative test scenario details

type TestSuite

type TestSuite struct {
	Tests []TestConfig `json:"tests"`
}

TestSuite represents instructions to run unit tests using test fixtures and mock service apis

type TestSuiteRunner

type TestSuiteRunner struct {
	TestSuite *TestSuite
	Delegate  TestRunnerDelegate
}

TestSuiteRunner runs given test suite config with the help of delegate supplied to it

func (*TestSuiteRunner) RunTests

func (runner *TestSuiteRunner) RunTests()

RunTests runs the tests from the test suite
