Functions

func PrepRPCTestConfig

func PrepRPCTestConfig(t *testing.T) *config.Config

PrepRPCTestConfig creates the require cometbft config on disk for rpctest package to work with halo app.

func RandomBytes

func RandomBytes(l int) []byte

RandomBytes returns a random byte slice of length l.

func RandomHash

func RandomHash() common.Hash

RandomHash returns a random 32-byte 256-bit hash.

func RequireGoldenBytes

func RequireGoldenBytes(t *testing.T, data []byte, opts ...func(*string))

RequireGoldenBytes asserts that a golden testdata file exists containing the exact data. This is heavily inspired from https://github.com/sebdah/goldie.

func RequireGoldenJSON

func RequireGoldenJSON(t *testing.T, data any, opts ...func(*string))

RequireGoldenJSON asserts that a golden testdata file exists containing the JSON serialized form of the data object. This is heavily inspired from https://github.com/sebdah/goldie.

func RequireNoError

func RequireNoError(tb testing.TB, err error)

RequireNoError asserts that err is nil. It also logs the error to show the stacktrace.

This can be used instead of require.NoError(t, err) to show the stacktrace in case of error.

func TempDir

func TempDir(t *testing.T) string

TempDir creates a temporary directory with a random name, as opposed to t.TempDir which uses consecutive numbers per test (001, 002 ...).

func WithFilename

func WithFilename(name string) func(*string)

WithFilename configures a custom golden test filename.
