java - Junit 不会断言 true

Question

按照给出的示例尝试创建我自己的 junit 测试，但是事情一直被 assertTrue(rs.next());

我正在尝试测试的代码

public void insertEmployee(Employees emp) {
        Connection conn = null;
        PreparedStatement ps = null;
        final String SQL = "INSERT INTO " + '"' + "Remburstment"+ '"' + ".employee values(?,?,?,?,?,?,?,?)";

        try {
            conn = ConnectionFactory.getConnection();
            ps = conn.prepareStatement(SQL);

            ps.setString(1, emp.getEmail());
            ps.setString(2, emp.getPassword());
            ps.setString(3, emp.getFirstName());
            ps.setString(4, emp.getLastName());
            ps.setBoolean(5, emp.getIsAManager());
            ps.setString(6, emp.getMyManagerEmail());
            ps.setString(7, emp.getMyManagerFirstName());
            ps.setString(8, emp.getMyManagerLastName());
            ps.execute();

        }catch(SQLException e) {
            e.printStackTrace();
        }finally {
            ConnectionClosers.closeConnection(conn);
            ConnectionClosers.closeStatement(ps);
        }

        LOGGY.debug("The EmployeeRepository insertEmployee was successfully called, and it created: " + emp);
    }

Junit 测试

        @Test
        public void TestInsertEmployee()
        {

            Connection conn= null;

            try
            {
                 conn = ConnectionFactory.getConnection();
                try(Statement stCheck=conn.createStatement())
                {
                    conn.setAutoCommit(false);

                    // Initial cleanup:
                    stCheck.executeUpdate("DELETE FROM " +'"' + "Remburstment"+ '"' + ".manager");
                    stCheck.executeUpdate("DELETE FROM " + '"' + "Remburstment"+ '"' + ".employee");


                    // Setting input parameters
                    String userName = "employee";
                    String Password = "password1";
                    String firstName = "bob";
                    String lastName = "Kelco";
                    String myManagerEmail = "manger";

                    Boolean isAManager = false;

                    // Do the call:

                    empRepository.insertManager(guy);
                    empRepository.insertEmployee(guy);

需要检查的事情很少

• 您是否使用 MockitoJUnitRunner 对类进行了注释？因为这会将应用程序作为真实的应用程序启动，以便可以实例化内部的对象。
• 这是 Junit 测试？我还没有看到这里发生任何 mock 。基本上你的 ResulSet 实际上应该被 Mocked。
• 我想是的，NPE 是因为您的 ConnectionFactory 给定的连接对象不包含您的数据库连接值，所以您会遇到异常。

始终尝试模拟处理业务逻辑的对象。
