Spock extension for TestContainers library, which allows to use Docker containers inside of Spock tests.
Specifying the @Testcontainers annotation will instruct Spock to start and stop all testcontainers accordingly. This annotation
can be mixed with Spock's @Shared annotation to indicate, that containers shouldn't be restarted between tests.
@Testcontainers
class DatabaseTest extends Specification {
@Shared
PostgreSQLContainer postgreSQLContainer = new PostgreSQLContainer()
.withDatabaseName("foo")
.withUsername("foo")
.withPassword("secret")
def "database is accessible"() {
given: "a jdbc connection"
HikariConfig hikariConfig = new HikariConfig()
hikariConfig.setJdbcUrl(postgreSQLContainer.jdbcUrl)
hikariConfig.setUsername("foo")
hikariConfig.setPassword("secret")
HikariDataSource ds = new HikariDataSource(hikariConfig)
when: "querying the database"
Statement statement = ds.getConnection().createStatement()
statement.execute("SELECT 1")
ResultSet resultSet = statement.getResultSet()
resultSet.next()
then: "result is returned"
int resultSetInt = resultSet.getInt(1)
resultSetInt == 1
}
}See the TestContainers documentation for more information about the underlying library.
The initial version of this project was heavily inspired by the excellent JUnit5 docker extension by FaustXVI.
