import cn.codeforfun.migrate.core.diff.DiffResult;
import cn.codeforfun.migrate.core.entity.DatabaseInfo;
import org.junit.Test;

import java.sql.SQLException;
import java.util.List;

private static final Integer FROM_PORT = 3306;
private static final String FROM_HOST = "localhost";
private static final String FROM_USERNAME = "root";
private static final String FROM_PASSWORD = "root";
private static final String FROM_TABLE = "test_db";

private static final Integer TO_PORT = 3307;
private static final String TO_HOST = "localhost";
private static final String TO_USERNAME = "root";
private static final String TO_PASSWORD = "root";
private static final String TO_TABLE = "test_db";

@Test
public void diff() throws SQLException {
    DatabaseInfo from = new DatabaseInfo(FROM_HOST, FROM_PORT, FROM_TABLE, FROM_USERNAME, FROM_PASSWORD);
    DatabaseInfo to = new DatabaseInfo(TO_HOST, TO_PORT, TO_TABLE, TO_USERNAME, TO_PASSWORD);
    Migrate migrate = new Migrate().from(from).to(to);
    DiffResult diffResult = migrate.diff();
    List<String> sqlList = diffResult.getSqlList();
    for (String sql : sqlList) {
        System.out.println(sql);
    }
}

@Test
public void update() throws SQLException {
    DatabaseInfo from = new DatabaseInfo(FROM_HOST, FROM_PORT, FROM_TABLE, FROM_USERNAME, FROM_PASSWORD);
    DatabaseInfo to = new DatabaseInfo(TO_HOST, TO_PORT, TO_TABLE, TO_USERNAME, TO_PASSWORD);
    Migrate migrate = new Migrate().from(from).to(to);
    migrate.update();
}
