java - Cucumber:无法将 DataTable 转换为 List。有一个表格单元格转换器，但表格太宽而无法使用

Question

功能文件:

Scenario: Login to application
Given I open my application
And I login with following credentials 
| admin | pass1234 |

步骤定义:

@When("^I login with following credentials$")
public void i_login_with_following_credentials(DataTable dt) {
    List<String> list = dt.asList(String.class);
    System.out.println("Username - " + list.get(0));
    System.out.println("Password - " + list.get(1));
}

错误:

io.cucumber.datatable.UndefinedDataTableTypeException: Can't convert DataTable to List<java.lang.String>.
There was a table cell converter but the table was too wide to use it.
Please reduce the table width or register a TableEntryTransformer or TableRowTransformer for java.lang.String.

<cucumber.version>5.4.1</cucumber.version>
<junit.version>4.13</junit.version>

能给点建议吗？具体应该添加什么？谢谢。

Answer 1

您正在尝试将数据表转换为字符串列表。因为列表是垂直的，并且 String 可以恰好占据一个单元格，所以 Cucumber 期望您有一张只有一列的表格。

| admin    |
| pass1234 | 

但您也可以转置数据表:

List<String> list = dt.transpose().asList(String.class)

或者直接访问单元格:

String username = dt.cell(0,0);
String password = dt.cell(0,1);
