testonly

Documentation

Overview

Package testonly contains code and data that should only be used by tests. Production code MUST NOT depend on anything in this package. This will be enforced by tools where possible.

As an example PEM encoded test certificates and helper functions to decode them are suitable candidates for being placed in testonly. However, nothing specific to a particular application should be added at this level. Do not add CT specific test data for example.

Constants

const DemoPrivateKey string = `` /* 294-byte string literal not displayed */

DemoPrivateKey is the private key itself; must only be used for testing purposes

const DemoPrivateKeyPass string = "towel"

DemoPrivateKeyPass is the password for DemoPrivateKey

const DemoPublicKey string = `` /* 178-byte string literal not displayed */

DemoPublicKey is the public key that corresponds to DemoPrivateKey.

Functions

func EnsureErrorContains

func EnsureErrorContains(t *testing.T, err error, s string)

EnsureErrorContains checks that an error contains a specific substring and fails a test with a fatal if it does not or the error was nil.

func ExtraDataForValue

func ExtraDataForValue(value []byte, sz uint) []byte

ExtraDataForValue builds a deterministic value for the extra data to be associated with a given value.

func HashKey

func HashKey(key string) []byte

HashKey converts a map key into a map index using SHA256. This preserves tests that precomputed indexes based on SHA256.

func MustDecodeBase64

func MustDecodeBase64(b64 string) []byte

MustDecodeBase64 expects a base 64 encoded string input and panics if it cannot be decoded

func MustHexDecode

func MustHexDecode(b string) []byte

MustHexDecode decodes its input string from hex and panics if this fails

func MustMarshalAny

func MustMarshalAny(t *testing.T, in proto.Message) *any.Any

MustMarshalAny is used in tests to Marshal proto messages into the protobuf.ptypes.any.Any used in the Trillian API and in storage. Failure to marshal will fail the test but the suite will continue.

func MustMarshalAnyNoT

func MustMarshalAnyNoT(in proto.Message) []byte

MustMarshalAnyNoT is used to Marshal proto messages into the protobuf.ptypes.any.Any used throughout the Trillian API and in storage. Use if testing.T not available. Failure to marshal will fail the test suite.

func MustToTimestampProto

func MustToTimestampProto(t time.Time) *tspb.Timestamp

MustToTimestampProto converts t to a Timestamp protobuf, or panics if this fails.

func NewSignerWithErr

func NewSignerWithErr(pubKey crypto.PublicKey, err error) crypto.Signer

NewSignerWithErr creates a signer that always returns err when Sign() is called.

func NewSignerWithFixedSig

func NewSignerWithFixedSig(pubKey crypto.PublicKey, sig []byte) crypto.Signer

NewSignerWithFixedSig creates a signer that always return sig when Sign() is called.

func RelativeToPackage

func RelativeToPackage(p string) string

RelativeToPackage returns the input path p as an absolute path, resolved relative to the caller's package. The working directory for Go tests is the dir of the test file. Using "plain" relative paths in test utilities is, therefore, brittle, as the directory structure may change depending on where the tests are placed.

func TransparentHash

func TransparentHash(key string) []byte

TransparentHash returns a key that can be visually inspected. This supports testing where it was nice to see what the key was.

Types

type ErrInvariant

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

ErrInvariant indicates that an invariant check failed, with details in msg.

func (ErrInvariant) Error

func (e ErrInvariant) Error() string

type MapContents

type MapContents struct {
	Rev int64
	// contains filtered or unexported fields
}

MapContents is a complete copy of the map's contents at a particular revision.

func (*MapContents) CheckContents

func (m *MapContents) CheckContents(leafInclusions []*trillian.MapLeafInclusion, extraSize uint) error

CheckContents compares information returned from the Map against a local copy of the map's contents.

func (*MapContents) Empty

func (m *MapContents) Empty() bool

Empty indicates if the contents are empty.

func (*MapContents) PickKey

func (m *MapContents) PickKey(prng *rand.Rand) []byte

PickKey randomly selects a key that already exists in a given copy of the map's contents. Assumes that the copy is non-empty.

func (*MapContents) RootHash

func (m *MapContents) RootHash(treeID int64, hasher hashers.MapHasher) ([]byte, error)

RootHash performs a slow and simple calculation of the root hash for a sparse Merkle tree with the given leaf contents.

func (*MapContents) String

func (m *MapContents) String() string

func (*MapContents) UpdatedWith

func (m *MapContents) UpdatedWith(rev uint64, leaves []*trillian.MapLeaf) *MapContents

UpdatedWith returns a new MapContents object that has been updated to include the given leaves and revision. A nil receiver object is allowed.

type MockServer

type MockServer struct {
	Admin       *tmock.MockTrillianAdminServer
	Log         *tmock.MockTrillianLogServer
	Map         *tmock.MockTrillianMapServer
	AdminClient trillian.TrillianAdminClient
	LogClient   trillian.TrillianLogClient
	MapClient   trillian.TrillianMapClient
	Addr        string
}

MockServer implements the TrillianAdminServer, the TrillianMapServer, and TrillianLogServer.

func NewMockServer

func NewMockServer(ctrl *gomock.Controller) (*MockServer, func(), error)

NewMockServer starts a server on a random port. Returns the started server, the listener it's using for connection and a close function that must be defer-called on the scope the server is meant to stop.

type VersionedMapContents

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

VersionedMapContents holds a collection of copies of a Map's contents across different revisions.

func (*VersionedMapContents) Empty

func (p *VersionedMapContents) Empty() bool

Empty indicates whether the most recent map contents are empty.

func (*VersionedMapContents) LastCopy

func (p *VersionedMapContents) LastCopy() *MapContents

LastCopy returns the most recent copy of the map's contents.

func (*VersionedMapContents) PickCopy

func (p *VersionedMapContents) PickCopy(prng *rand.Rand) *MapContents

PickCopy returns a previous copy of the map's contents at random, returning nil if there are no local copies.

func (*VersionedMapContents) PrevCopy

func (p *VersionedMapContents) PrevCopy(which int) *MapContents

PrevCopy returns the specified copy of the map's contents.

func (*VersionedMapContents) UpdateContentsWith

func (p *VersionedMapContents) UpdateContentsWith(rev uint64, leaves []*trillian.MapLeaf) (*MapContents, error)

UpdateContentsWith stores a new copy of the Map's contents, updating the most recent copy with the given leaves. Returns the updated contents.
