de.softwareforge.testing.postgres.junit5.EmbeddedPgExtension

All Implemented Interfaces:

AfterAllCallback, AfterEachCallback, BeforeAllCallback, BeforeEachCallback, Extension, ParameterResolver, TestInstantiationAwareExtension

public final class EmbeddedPgExtension
extends Object
implements BeforeAllCallback, AfterAllCallback, BeforeEachCallback, AfterEachCallback, ParameterResolver

A JUnit 5 extension that manages an embedded PostgreSQL database server.

This extension can provide the EmbeddedPostgres instance, a DatabaseInfo or a DataSource object as test parameters.

• Using a DatabaseInfo parameter is equivalent to calling createDatabaseInfo().
• Using a DataSource parameter is equivalent to calling createDataSource().

Constructor Details

EmbeddedPgExtension

public EmbeddedPgExtension()

Default constructor which allows using this extension with the ExtendWith annotation.

This is equivalent to using

     @RegisterExtension
     public static EmbeddedPgExtension pg = MultiDatabaseBuilder.instanceWithDefaults().build();
     

Since:

3.0

Method Details

createDataSource

@Nonnull
public DataSource createDataSource()
                            throws SQLException

Returns a data source. Depending on the mode it returns a datasource connected to the same database (single mode) or a new database (multi mode) on every call.

Returns:

A DataSource instance. This is never null.

Throws:

SQLException - If a problem connecting to the database occurs.

createDatabaseInfo

@Nonnull
public DatabaseInfo createDatabaseInfo()
                                throws SQLException

Returns a new DatabaseInfo describing a database connection.

Depending on the mode, this either describes the same database (single mode) or a new database (multi mode).

Returns:

A DatabaseInfo instance. This is never null.

Throws:

SQLException - If a problem connecting to the database occurs.
