Types

type InMemSpannerServer added in v0.42.0 

type InMemSpannerServer interface {
	spannerpb.SpannerServer

	// Stops this server.
	Stop()

	// Resets the in-mem server to its default state, deleting all sessions and
	// transactions that have been created on the server. Mocked results are
	// not deleted.
	Reset()

	// Sets an error that will be returned by the next server call. The server
	// call will also automatically clear the error.
	SetError(err error)

	// Puts a mocked result on the server for a specific sql statement. The
	// server does not parse the SQL string in any way, it is merely used as
	// a key to the mocked result. The result will be used for all methods that
	// expect a SQL statement, including (batch) DML methods.
	PutStatementResult(sql string, result *StatementResult) error

	// Removes a mocked result on the server for a specific sql statement.
	RemoveStatementResult(sql string)

	// Aborts the specified transaction . This method can be used to test
	// transaction retry logic.
	AbortTransaction(id []byte)

	// Puts a simulated execution time for one of the Spanner methods.
	PutExecutionTime(method string, executionTime SimulatedExecutionTime)
	// Freeze stalls all requests.
	Freeze()
	// Unfreeze restores processing requests.
	Unfreeze()

	TotalSessionsCreated() uint
