tidb-lite test

Chinese README

tidb-lite is a package, we can use this package to create a TiDB server with mocktikv mode in your application or unit test.

Interface

  • func NewTiDBServer(options *Options) (*TiDBServer, error)

    Create a TiDB Server, can use options to set the path which used to save db's data and this server's port.

  • func GetTiDBServer() (*TiDBServer, error)

    Get the exist TiDB Server.

  • func (t *TiDBServer) CreateConn() (*sql.DB, error)

    Create a database connection.

  • func (t *TiDBServer) Close()

    Close TiDB Server.

  • func (t *TiDBServer) CloseGracefully()

    Close TiDB server gracefully.

Example

We can read the code under example.go to know how to use tidb-lite.

In example.go defines a function GetRowCount to calculate the count of a table with condition.

In example_test.go use code below to create a TiDB server and get the database's connection used for unit test.

tidbServer, err := tidblite.NewTiDBServer(tidblite.NewOptions(c.MkDir()))
c.Assert(err, IsNil)
defer tidbServer.Close()

dbConn, err := tidbServer.CreateConn()
c.Assert(err, IsNil)

And then we can use the dbConn to generate test data, and then check function GetRowCount's correctness.

Notice

tidb-lite only allows one TiDB instance to run at a time. You need to make sure that the existing TiDB instance is closed before creating a new instance.
