  - getDataSource
```
public static DataSource getDataSource(String databaseName)
```
    Returns the DataSource that connects to the test database
    
    返回:
    
    The DataSource that connects to the test database
  - getDataSource
```
public static DataSource getDataSource()
```
    Returns the DataSource that connects to the test database
    
    返回:
    
    The DataSource that connects to the test database
  - flushDatabaseUpdates
```
public static void flushDatabaseUpdates()
```
    Flushes all pending updates to the database. This method is useful when the effect of updates needs to be checked directly on the database.
    A typical usage of this method is, when updates were issues to the database using hibernate, making sure that these updates are flushed, to be able to check the effect of these updates using plain old JDBC.
  - startTransaction
```
public static void startTransaction()
```
    Starts a new transaction on the transaction manager configured in unitils
  - commitTransaction
```
public static void commitTransaction()
```
    Commits the current unitils transaction
  - rollbackTransaction
```
public static void rollbackTransaction()
```
    Performs a rollback of the current unitils transaction
  - updateDatabase
```
public static void updateDatabase()
```
    Determines whether the test database is outdated and, if that is the case, updates the database with the latest changes. See DBMaintainer for more information.
  - updateDatabase
```
public static void updateDatabase(String databaseName)
```
    Determines whether the test database is outdated and, if that is the case, updates the database with the latest changes. See DBMaintainer for more information.
  - resetDatabaseState
```
public static void resetDatabaseState()
```
    Updates the database version to the current version, without issuing any other updates to the database. This method can be used for example after you've manually brought the database to the latest version, but the database version is not yet set to the current one. This method can also be useful for example for reinitializing the database after having reorganized the scripts folder.
  - resetDatabaseState
```
public static void resetDatabaseState(String databaseName)
```
    Updates the database version to the current version, without issuing any other updates to the database. This method can be used for example after you've manually brought the database to the latest version, but the database version is not yet set to the current one. This method can also be useful for example for reinitializing the database after having reorganized the scripts folder.
  - clearSchemas
```
public static void clearSchemas()
```
    Clears all configured schema's. I.e. drops all tables, views and other database objects.
  - clearSchemas
```
public static void clearSchemas(String databaseName)
```
    Clears all configured schema's. I.e. drops all tables, views and other database objects.
  - cleanSchemas
```
public static void cleanSchemas()
```
    Cleans all configured schema's. I.e. removes all data from its database tables.
  - cleanSchemas
```
public static void cleanSchemas(String databaseName)
```
    Cleans all configured schema's. I.e. removes all data from its database tables.
  - disableConstraints
```
public static void disableConstraints()
```
    Disables all foreign key and not-null constraints on the configured schema's.
  - disableConstraints
```
public static void disableConstraints(String databaseName)
```
    Disables all foreign key and not-null constraints on the configured schema's.
  - updateSequences
```
public static void updateSequences()
```
    Updates all sequences that have a value below a certain configurable treshold to become equal to this treshold
  - updateSequences
```
public static void updateSequences(String databaseName)
```
    Updates all sequences that have a value below a certain configurable treshold to become equal to this treshold
  - restartSequences
```
public static void restartSequences(String databaseName)
```
    Sets all the sequences to the lowest acceptable value. This can be defined with the property "sequenceUpdater.sequencevalue.lowestacceptable".
  - generateDatasetDefinition
```
public static void generateDatasetDefinition()
```
    Generates a definition file that defines the structure of dataset's, i.e. a XSD of DTD that describes the structure of the database.
  - generateDatasetDefinition
```
public static void generateDatasetDefinition(String databaseName)
```
    Generates a definition file that defines the structure of dataset's, i.e. a XSD of DTD that describes the structure of the database.
  - getGoodConnection
```
public static Connection getGoodConnection(Connection connection,
                                           DataSource dataSource)
```
    This method gets a Connection from the DataSource and checks if it is a oracle.jdbc.driver.OracleConnection. There is a bug with commons-dbcp 1.4: if you want to create a oracle.sql.BLOB or a Clob than you must get the inner Connection but you get another Connection. This is fixed in this method.
