java - mockrunner jdbc - 结果集中没有列/行

Question

我第一次尝试使用mockrunner 设置测试。连接已建立，但我只得到一个空结果集。这是精简的工作示例:

import com.mockrunner.jdbc.BasicJDBCTestCaseAdapter;
import com.mockrunner.jdbc.StatementResultSetHandler;
import com.mockrunner.mock.jdbc.MockResultSet;

public class ExtractDataTest extends BasicJDBCTestCaseAdapter {
    @Test
    public void test() throws Exception {
        StatementResultSetHandler statementHandler = getJDBCMockObjectFactory()
                .getMockConnection().getStatementResultSetHandler();
        MockResultSet resultMock = statementHandler.createResultSet();
        resultMock.addColumn("ID", new Object[]{"1"});
        resultMock.addColumn("USERNAME", new Object[]{"foobar"});
        statementHandler.prepareGlobalResultSet(resultMock);

        Connection con = DriverManager.getConnection( "a", "b", "c");
        System.out.println(con); //com.mockrunner.mock.jdbc.MockConnection@29d8a2c5
        PreparedStatement stmtObjects = con.prepareStatement(
                  "SELECT * FROM USER");
        ResultSet rs = stmtObjects.executeQuery();
        System.out.println(rs); // empty result set
        System.out.println(this.getExecutedSQLStatements()); // []
    }
}

预期输出是包含“1”和“foobar”的结果集，以及执行的 SQL 语句。

您需要使用PreparedStatementResultSetHandler。

这是测试的有效修改版本:

@Test
public void test() throws Exception {
    PreparedStatementResultSetHandler statementHandler = getJDBCMockObjectFactory()
            .getMockConnection().getPreparedStatementResultSetHandler();
    MockResultSet resultMock = statementHandler.createResultSet();
    resultMock.addColumn("ID", new Object[]{"1"});
    resultMock.addColumn("USERNAME", new Object[]{"foobar"});
    statementHandler.prepareGlobalResultSet(resultMock);

    Connection con = DriverManager.getConnection( "a", "b", "c");
    PreparedStatement stmtObjects = con.prepareStatement(
            "SELECT * FROM USER");
    ResultSet rs = stmtObjects.executeQuery();
    assertTrue(rs.next());
    //System.out.println(rs); 
    //System.out.println(getExecutedSQLStatements()); 
    verifySQLStatementExecuted("SELECT * FROM USER");
}
