func ApplyMigration ¶

func ApplyMigration(t *testing.T,
	beforeMigration, afterMigration, migrationFunc func(tx kvdb.RwTx) error,
	shouldFail bool)

ApplyMigration is a helper test function that encapsulates the general steps which are needed to properly check the result of applying migration function.

func ApplyMigrationWithDB ¶

func ApplyMigrationWithDB(t testing.TB, beforeMigration,
	afterMigration func(db kvdb.Backend) error,
	migrationFunc func(db kvdb.Backend) error, shouldFail bool)

ApplyMigrationWithDB is a helper test function that encapsulates the general steps which are needed to properly check the result of applying migration function. This function differs from ApplyMigration as it requires the supplied migration functions to take a db instance and construct their own database transactions.

func DumpDB ¶

func DumpDB(tx kvdb.RTx, rootKey []byte) error

DumpDB dumps go code describing the contents of the database to stdout. This function is only intended for use during development.

Example output:

map[string]interface{}{
	hex("1234"): map[string]interface{}{
		"human-readable": hex("102030"),
		hex("1111"): hex("5783492373"),
	},
}

func Hex ¶

func Hex(value string) string

Hex is a test helper function to convert readable hex arrays to raw byte strings.

func MakeDB ¶

func MakeDB(t testing.TB) (kvdb.Backend, error)

MakeDB creates a new instance of the ChannelDB for testing purposes.

func RestoreDB ¶

func RestoreDB(tx kvdb.RwTx, rootKey []byte, data map[string]interface{}) error

RestoreDB primes the database with the given data set.

func VerifyDB ¶

func VerifyDB(tx kvdb.RTx, rootKey []byte, data map[string]interface{}) error

VerifyDB verifies the database against the given data set.
