- 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>_<suffix>

  - UniqueDatabase
```
public UniqueDatabase(String serverName,
                      String databaseName)
```
    Creates an instance with given Debezium logical name and database name
    
    Parameters:
    
    serverName - - logical Debezium server name
    
    databaseName - - the name of the database (prix)
  - UniqueDatabase
```
public UniqueDatabase(String serverName,
                      String databaseName,
                      String charset)
```
    Creates an instance with given Debezium logical name and database name and a set default charset
    
    Parameters:
    
    serverName - - logical Debezium server name
    
    databaseName - - the name of the database (prix)
  - UniqueDatabase
```
public UniqueDatabase(String serverName,
                      String databaseName,
                      UniqueDatabase sibling)
```
    Creates an instance with given Debezium logical name and database name and id suffix same as another database. This is handy for tests that need multpli databases and can use regex based whitelisting.
    
    Parameters:
    
    serverName - - logical Debezium server name
    
    databaseName - - the name of the database (prix)
    
    sibling - - a database whose unique suffix will be used
