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 CompactMerkleTreeLeafTestNodeHashes

func CompactMerkleTreeLeafTestNodeHashes() [][][]byte

CompactMerkleTreeLeafTestNodeHashes returns the CompactMerkleTree.node state that must result after each of the leaf additions returned by MerkleTreeLeafTestInputs(), as described above.

func EmptyMerkleTreeRootHash

func EmptyMerkleTreeRootHash() []byte

EmptyMerkleTreeRootHash returns the expected root hash for an empty Merkle Tree that uses SHA256 hashing.

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 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 MerkleTreeLeafTestInputs

func MerkleTreeLeafTestInputs() [][]byte

MerkleTreeLeafTestInputs returns a slice of leaf inputs that may be used in compact Merkle tree test cases. They are intended to be added successively, so that after each addition the corresponding root from MerkleTreeLeafTestRoots gives the expected Merkle tree root hash.

func MerkleTreeLeafTestRootHashes

func MerkleTreeLeafTestRootHashes() [][]byte

MerkleTreeLeafTestRootHashes returns a slice of Merkle tree root hashes that correspond to the expected tree state for the leaf additions returned by MerkleTreeLeafTestInputs(), as described above.

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) *any.Any

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 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.
