Functions

func AllJSONValueTypes 

func AllJSONValueTypes() []ldvalue.ValueType

AllJSONValueTypes returns every possible value of the ldvalue.ValueType enum, corresponding to the standard JSON types (including null).

func AllSDKValueTypes 

func AllSDKValueTypes() []servicedef.ValueType

AllSDKValueTypes returns every possible value of the servicedef.ValueType enum, corresponding to the logical types used in strongly-typed SDK APIs-- that is, the result types you could request when evaluating a flag. So, unlike AllJSONValueTypes, int and double are different, there is no null, and the "any" type is used for arbitrary JSON values.

func ClientSideFlagShouldHaveDebuggingEnabledUntil 

func ClientSideFlagShouldHaveDebuggingEnabledUntil(t time.Time) func(*mockld.ClientSDKFlagWithKey)

ClientSideFlagShouldHaveDebuggingEnabledUntil is a convenience function for configuring a client-side flag to have debugging enabled until the specified time.

func ClientSideFlagShouldHaveEvalReason 

func ClientSideFlagShouldHaveEvalReason(reason ldreason.EvaluationReason) func(*mockld.ClientSDKFlagWithKey)

ClientSideFlagShouldHaveEvalReason is a convenience function for configuring a client-side flag to have an evaluation reason.

func ClientSideFlagShouldHaveFullEventTracking 

func ClientSideFlagShouldHaveFullEventTracking(f *mockld.ClientSDKFlagWithKey)

ClientSideFlagShouldHaveFullEventTracking is a convenience function for configuring a client-side flag to have full event tracking enabled (by setting TrackEvents to true).

func FlagShouldAlwaysHaveDebuggingEnabled 

func FlagShouldAlwaysHaveDebuggingEnabled(builder *ldbuilders.FlagBuilder)

FlagShouldAlwaysHaveDebuggingEnabled is a convenience function for configuring a flag to have debugging enabled (by setting DebugEventsUntilDate to a far future time).

func FlagShouldHaveDebuggingEnabledUntil 

func FlagShouldHaveDebuggingEnabledUntil(t time.Time) func(*ldbuilders.FlagBuilder)

FlagShouldHaveDebuggingEnabledUntil is a convenience function for configuring a flag to have debugging enabled until the specified time.

func FlagShouldHaveFullEventTracking 

func FlagShouldHaveFullEventTracking(builder *ldbuilders.FlagBuilder)

FlagShouldHaveFullEventTracking is a convenience function for configuring a flag to have full event tracking enabled (by setting TrackEvents to true).

func FlagShouldProduceThisEvalReason 

func FlagShouldProduceThisEvalReason(
	reason ldreason.EvaluationReason,
	matchContexts ...ldcontext.Context,
) func(*ldbuilders.FlagBuilder)

FlagShouldProduceThisEvalReason is a convenience function for configuring a flag to produce a specific evaluation reason for all evaluations. If specific contexts should be matched, pass them in matchContexts-- however, this implementation only works if they are single-kind contexts that are all of the same kind.

func GroupTestSuitesByName 

func GroupTestSuitesByName[V HasName](suites []V) [][]V

GroupTestSuitesByName converts a list of test suites to a list of lists, grouped by their name property.

See comments in common_tests_eval.go for an example of why we may want to do this.

func LoadAndParseAllTestSuites 

func LoadAndParseAllTestSuites[V any](t *ldtest.T, dirName string) []V

LoadAndParseAllTestSuites calls LoadAllDataFiles and then parses each of the resulting SourceInfos as JSON or YAML into the specified type.

func MakeStandardTestValues 

func MakeStandardTestValues() []ldvalue.Value

MakeStandardTestValues returns a list of values that cover all JSON types, *and* all special values that might conceivably be handled wrong in SDK implementations. For instance, we should check both non-empty and empty strings, and both zero and non-zero numbers, to make sure "" and 0 ares not being treated the same as "undefined/null".

func ParseJSONOrYAML 

func ParseJSONOrYAML(data []byte, target interface{}) error

ParseJSONOrYAML is used in the same way as json.Unmarshal, but if the data is YAML and not JSON, it will convert the YAML to JSON and then parse it as JSON.

Types

type ClientSideFlagFactory 

type ClientSideFlagFactory struct {
	// contains filtered or unexported fields
}

ClientSideFlagFactory is a test data generator that produces mockld.ClientSDKFlagWithKey instances.

func NewClientSideFlagFactory 

func NewClientSideFlagFactory(
	keyPrefix string,
	valueFactory ValueFactoryBySDKValueType,
	builderActions ...func(*mockld.ClientSDKFlagWithKey),
) *ClientSideFlagFactory

NewClientSideFlagFactory creates a ClientSideFlagFactory with the specified configuration.

The valueFactory parameter provides the value that each flag will return for evaluations. The builderActions, if any, will be run each time a flag is created. Each flag will have a unique key beginning with the specified prefix.

func (*ClientSideFlagFactory) MakeFlagForValueType 

func (f *ClientSideFlagFactory) MakeFlagForValueType(valueType servicedef.ValueType) mockld.ClientSDKFlagWithKey

MakeFlagForValueType creates a new flag configuration. The flag variation will be of the specified type.

func (*ClientSideFlagFactory) ReuseFlagForValueType 

func (f *ClientSideFlagFactory) ReuseFlagForValueType(valueType servicedef.ValueType) mockld.ClientSDKFlagWithKey

ReuseFlagForValueType is the same as MakeFlagForValueType except that if MakeFlagForValueType has already been called for the same type, it will return the same flag and not create a new one.

type ContextFactory 

type ContextFactory struct {
	// contains filtered or unexported fields
}

ContextFactory is a test data generator that produces ldcontext.Context instances.

func NewContextFactoriesForExercisingAllAttributes 

func NewContextFactoriesForExercisingAllAttributes(
	prefix string,
) []*ContextFactory

NewContextFactoriesForExercisingAllAttributes produces a list of ContextFactory instances that use different subsets of the context schema, to verify that context attributes are encoded correctly when they are sent to evaluation endpoints.

The returned list will include factories for 1. single-kind Contexts with no attributes other than kind and key, 2. single-kind Contexts with every possible kind of attribute, 3. multi-kind Contexts that combine 1 and 2.

Each will have an appropriate Description, so the logic for running a test against each one can look like this: 

for _, contexts := range data.NewContextFactoriesForExercisingAllAttributes("NameOfTest") {
    t.Run(contexts.Description(), func(t *testing.T) {
        context := contexts.NextUniqueContext() // do something with this
    })
}

func NewContextFactoriesForSingleAndMultiKind 

func NewContextFactoriesForSingleAndMultiKind(
	prefix string, builderActions ...func(*ldcontext.Builder),
) []*ContextFactory

NewContextFactoriesForSingleAndMultiKind produces a list of ContextFactory instances for testing SDK functionality that may behave differently for different Context variants.

The returned list will include factories for 1. single-kind Contexts of the default kind, 2. single-kind Contexts of a different kind, 3. multi-kind Contexts. The reason for checking single vs. multi-kind is that we want to make sure the SDK correctly enumerates the kinds when it populates the contextKeys property in event data. The reason for checking the default kind vs. a non-default kind is that it affects the deduplication logic for index events.

Each will have an appropriate Description, so the logic for running a test against each one can look like this: 

for _, contexts := range data.NewContextFactoriesForSingleAndMultiKind("NameOfTest") {
    t.Run(contexts.Description(), func(t *testing.T) {
        context := contexts.NextUniqueContext() // do something with this
    })
}

func NewContextFactory 

func NewContextFactory(prefix string, builderActions ...func(*ldcontext.Builder)) *ContextFactory

NewContextFactory creates a ContextFactory that produces single-kind Contexts.

Each generated Context will have a unique key that starts with the prefix string. The builderActions, if any, will be run against the builder for each Context. If no actions are specified, then it will have no properties other than the key, and its kind will be ldcontext.DefaultKind ("user").

func NewMultiContextFactory 

func NewMultiContextFactory(
	prefix string,
	kinds []ldcontext.Kind,
	builderActions ...func(*ldcontext.Builder),
) *ContextFactory

NewMultiContextFactory creates a ContextFactory that produces multi-kind Contexts.

Each generated multiple context will contain an individual context for each of the kinds in the kinds parameter. If builderActions are specified, the first one will be run for the first kind, the second for the second, etc. Each individual context will have a unique key that starts with the prefix string.

func (*ContextFactory) Description 

func (f *ContextFactory) Description() string

Description returns a descriptive string, if this ContextFactory was produced by a method such as NewContextFactoriesForSingleAndMultiKind that provides one.

func (*ContextFactory) NextUniqueContext 

func (f *ContextFactory) NextUniqueContext() ldcontext.Context

NextUniqueContext creates a Context instance.

func (*ContextFactory) Prefix 

func (f *ContextFactory) Prefix() string

func (*ContextFactory) SetKeyDisambiguatorValueSameAs 

func (f *ContextFactory) SetKeyDisambiguatorValueSameAs(f1 *ContextFactory)

SetKeyDisambiguatorValueSameAs overrides the usual "add a randomized value to all the keys produced by this factory" logic, which is meant to avoid key collisions, so that these two factories will use the *same* randomized value. This is for tests where we want to verify, for instance, that two contexts with the same key but different kinds are treated as distinct.

type FlagFactory 

type FlagFactory struct {
	// contains filtered or unexported fields
}

FlagFactory is a test data generator that produces ldmodel.FeatureFlag instances.

func NewFlagFactory 

func NewFlagFactory(
	keyPrefix string,
	valueFactory ValueFactoryBySDKValueType,
	builderActions ...func(*ldbuilders.FlagBuilder),
) *FlagFactory

NewFlagFactory creates a FlagFactory with the specified configuration.

The valueFactory parameter provides the value that each flag will return for evaluations. The builderActions, if any, will be run each time a flag is created. Each flag will have a unique key beginning with the specified prefix.

func (*FlagFactory) MakeFlag 

func (f *FlagFactory) MakeFlag() ldmodel.FeatureFlag

MakeFlag creates a new flag configuration. Use this when the value type is not significant to the test; it will default to using string variations, since those are more easily readable in test output.

func (*FlagFactory) MakeFlagForValueType 

func (f *FlagFactory) MakeFlagForValueType(valueType servicedef.ValueType) ldmodel.FeatureFlag

MakeFlagForValueType creates a new flag configuration. The flag variations will be of the specified type.

func (*FlagFactory) ReuseFlagForValueType 

func (f *FlagFactory) ReuseFlagForValueType(valueType servicedef.ValueType) ldmodel.FeatureFlag

ReuseFlagForValueType is the same as MakeFlagForValueType except that if MakeFlagForValueType has already been called for the same type, it will return the same flag and not create a new one.

type GenericFactory 

type GenericFactory[ParamT, ResultT any] interface {
	Get(param ParamT) ResultT
}

type HasName 

type HasName interface {
	GetName() string
}

type MemoizingFactory 

type MemoizingFactory[ParamT comparable, ResultT any] struct {
	// contains filtered or unexported fields
}

func NewMemoizingClientSideFlagFactory 

func NewMemoizingClientSideFlagFactory(
	startingVersion int,
	factoryFn func(servicedef.ValueType) mockld.ClientSDKFlagWithKey,
) *MemoizingFactory[servicedef.ValueType, mockld.ClientSDKFlagWithKey]

func NewMemoizingFlagFactory 

func NewMemoizingFlagFactory(
	startingVersion int,
	factoryFn func(servicedef.ValueType) ldmodel.FeatureFlag,
) *MemoizingFactory[servicedef.ValueType, ldmodel.FeatureFlag]

func (*MemoizingFactory[P, R]) Create 

func (f *MemoizingFactory[P, R]) Create(param P) R

func (*MemoizingFactory[P, R]) GetOrCreate 

func (f *MemoizingFactory[P, R]) GetOrCreate(param P) R

type SourceInfo 

type SourceInfo struct {
	FilePath string
	BaseName string
	Params   map[string]ldvalue.Value
	Data     []byte
}

SourceInfo represents JSON or YAML data that was read from a file, after post-processing to expand constants and parameters. For non-parameterized tests, you will get one SourceInfo per file. For parameterized tests, there can be many instances per file, each with its own version of Data. See ReadFile and docs/data_files.md.

func LoadAllDataFiles 

func LoadAllDataFiles(path string) ([]SourceInfo, error)

LoadAllDataFiles reads all data files in a directory and performs any necessary constant/parameter substitutions. It can return more than one SourceInfo per file, because any file can be a parameterized test. See docs/data_files.md.

The path parameter is relative to data/data-files.

func LoadDataFile 

func LoadDataFile(path string) ([]SourceInfo, error)

LoadDataFile reads a data file and performs any necessary constant/parameter substitutions. It can return more than one SourceInfo because any file can be a parameterized test. See docs/data_files.md.

The path parameter is relative to data/data-files.

func (SourceInfo) ParamsString 

func (s SourceInfo) ParamsString() string

func (SourceInfo) ParseInto 

func (s SourceInfo) ParseInto(target interface{}) error

type ValueFactoryBySDKValueType 

type ValueFactoryBySDKValueType func(valueType servicedef.ValueType) ldvalue.Value

ValueFactoryBySDKValueType is a data generator function type that produces a different ldvalue.Value for each of the logical types supported by strongly-typed SDKs.

func MakeValueFactoriesBySDKValueType 

func MakeValueFactoriesBySDKValueType(howMany int) []ValueFactoryBySDKValueType

MakeValueFactoriesBySDKValueType creates the specified number of ValueByTypeFactory generators, each producing different values from the others (insofar as possible, given that there are only two possible values for the boolean type).

func MakeValueFactoryBySDKValueType 

func MakeValueFactoryBySDKValueType() ValueFactoryBySDKValueType

MakeValueFactoryBySDKValueType creates a ValueByTypeFactory generator providing a different value for each servicedef.ValueType.

func SingleValueForAllSDKValueTypes 

func SingleValueForAllSDKValueTypes(value ldvalue.Value) ValueFactoryBySDKValueType

SingleValueForAllSDKValueTypes creates a ValueByTypeFactory generator that always returns the same value.
