### Question:
Configuration { public List<Mapping> getMappings() { return mappings; }  String getDataSource(); String getDestinationBucket(); String getSourceBucket(); String getSqlBucket(); String getFileSystem(); List<Mapping> getMappings(); @Override String toString();  }### Answer:
@Test public void testGetSourceFiles() { List<String> files = new ArrayList<String>(); files.add("file1.csv"); assertEquals(files, configuration.getMappings().get(0).getSourceFiles()); files.add("file2.csv"); assertEquals(files, configuration.getMappings().get(1).getSourceFiles()); }
@Test public void testGetSqlFile() { assertEquals("sql/sql1.sql", configuration.getMappings().get(0).getSqlFile()); assertEquals("sql2.sql", configuration.getMappings().get(1).getSqlFile()); }
