Class UniqueDatabase

java.lang.Object
io.debezium.connector.mysql.UniqueDatabase
public class UniqueDatabase extends Object
Create and populate a unique instance of a MySQL database for each run of JUnit test. A user of class needs to provide a logical name for Debezium and database name. It is expected that there is a init file in src/test/resources/ddl/<database_name>.sql. The database name is enriched with a unique suffix that guarantees complete isolation between runs <database_name&gt_<suffix&gt
