Question

我的功能文件中有以下示例小黄瓜场景：

Scenario: Book an FX Trade
 Given trades with the following details are created:
   |buyCcy |sellCcy |amount   |date       |
   |EUR    |USD     |12345.67 |23-11-2017 |
   |GBP    |EUR     |67890.12 |24-11-2017 |
 When the trades are executed
 Then the trades are confirmed

在我的胶水文件中，我可以将数据表映射到对象Trade，作为开箱即用的黄瓜解决方案：

@When("^trades with the following details are created:$")
public void trades_with_the_following_details_are_created(List<Trade> arg1) throws Throwable {
        //do something with arg1
}

我想要实现的目标：
通过执行以下操作提高我的小黄瓜方案的可读性：

垂直移调数据表，如果我的对象有大约10个字段，这将提高可读性

使用别名

替换字段/列名称

示例：

Scenario: Book an FX Trade
 Given trades with the following details are created:
   |Buy Currency  | EUR        | GBP        |
   |Sell Currency | USD        | EUR        |
   |Amount        | 12345.67   | 67890.12   |
   |Date          | 23-11-2017 | 24-11-2017 |
 When the trades are executed
 Then the trades are confirmed

我希望表格能够以多于或少于2个数据集/列的方式呈现动态。实现这一目标的最佳方法是什么？

其他信息：
语言：Java 8
黄瓜版：1.2.5

Trade POJO就像：

public class Trade {
    private String buyCcy;
    private String sellCcy;
    private String amount;
    private String date;

    /**
     * These fields are growing and may have around 10 or more....
     * private String tradeType;
     * private String company;
     */

    public Trade() {
    }

    /**
     * accessors here....
     */
}

Answer 1

如果在功能文件中将表格指定为

|buyCcy  | EUR        | GBP        |
|sellCcy | USD        | EUR        |
|amount  | 12345.67   | 67890.12   |
|date    | 23-11-2017 | 24-11-2017 |

您可以使用以下粘合代码（使用已发布的Trade类，假设已实施正确的toString()方法

@Given("^trades with the following details are created:$")
public void tradeWithTheFollowingDetailsAreCreated(DataTable dataTable) throws Exception {
    // transpose - transposes the table from the feature file
    // asList - creates a `List<Trade>`
    List<Trade> list = dataTable.transpose().asList(Trade.class);
    list.stream().forEach(System.out::println);
}

输出

Trade{buyCcy=EUR, sellCcy=USD, amount=12345.67, date=23-11-2017}
Trade{buyCcy=GBP, sellCcy=EUR, amount=67890.12, date=24-11-2017}
