Тест Junit: NoSuchElementException, Mock getConnection ⇐ JAVA

[Anonymous]

Я пытаюсь написать тест Junit, но получаю исключение java.util.NoSuchElementException. Имея ограниченные знания о макетах и ​​junit, я понимаю, что DriverManager.getConnection необходимо имитировать/заглушить.
Как я могу это сделать. Любая помощь приветствуется.
Цель состоит в том, чтобы запустить тест junit без доступа к фактическому источнику базы данных.
public class DatabricksQueryExecutorTests {
@Test
public void testReadUnityTableDataAsJson() throws SQLException {
// Create a mock DatabricksConfig object
DatabricksConfig databricksConfig = new DatabricksConfig();
databricksConfig.setHost("example.com");
databricksConfig.setHttpPath("/api/2.0");
databricksConfig.setAccessToken("your-access-token");
databricksConfig.setUsername("your-username");

// Create a mock SQL query
String sqlQuery = "SELECT * FROM table";

// Create a mock ResultSet with sample data
ResultSet resultSet = Mockito.mock(ResultSet.class);
Mockito.when(resultSet.next()).thenReturn(true, false);
Mockito.when(resultSet.getMetaData()).thenReturn(Mockito.mock(ResultSetMetaData.class));
Mockito.when(resultSet.getMetaData().getColumnCount()).thenReturn(2);
Mockito.when(resultSet.getMetaData().getColumnName(1)).thenReturn("column1");
Mockito.when(resultSet.getMetaData().getColumnName(2)).thenReturn("column2");
Mockito.when(resultSet.getString(1)).thenReturn("value1");
Mockito.when(resultSet.getString(2)).thenReturn("value2");

// Create a mock Connection and Statement
Connection connection = Mockito.mock(Connection.class);
Statement statement = Mockito.mock(Statement.class);
Mockito.when(connection.createStatement()).thenReturn(statement);
Mockito.when(connection.createStatement().executeQuery(sqlQuery)).thenReturn(resultSet);

// Create an instance of DatabricksQueryExecutor
DatabricksQueryExecutor queryExecutor = new DatabricksQueryExecutor();

// Call the method under test
JsonArray jsonArray = queryExecutor.readUnityTableDataAsJson(sqlQuery, databricksConfig);

// Verify the result
Assertions.assertEquals(1, jsonArray.size());
JsonObject jsonObject = jsonArray.get(0).getAsJsonObject();
Assertions.assertEquals("value1", jsonObject.get("column1").getAsString());
Assertions.assertEquals("value2", jsonObject.get("column2").getAsString());
}
}
