【中文标题】Cucumber DataTable 错误 - io.cucumber.datatable.UndefinedDataTableTypeException：无法将 DataTable 转换为 cucumber.api.DataTable【英文标题】：Cucumber DataTable Error - io.cucumber.datatable.UndefinedDataTableTypeException: Can't convert DataTable to cucumber.api.DataTable 【发布时间】：2019-08-30 16:10:10 【问题描述】：尝试使用 cucumber/selenium/java/intelliJ 运行场景，但在其中一个步骤中收到有关 DataTable 的错误。在我开始使用测试运行器并更改了一些东西之前，dataTable 工作正常并正确转换了该步骤的参数，但我无法让它工作。
这是错误：
cucumber.runtime.CucumberException: Could not convert arguments for step [^I enter the following login details:$] defined at 'Steps.MaStepdefs.iEnterTheFollowingLoginDetails(DataTable) in file:/C:/Users/Kristian.Senior/Desktop/CukesReporting/target/test-classes/'.
It appears you did not register a data table type. The details are in the stacktrace below.

这是我的场景：
Feature: LoginFeature
This deals with logging in
Scenario: Log in with correct username
Given I navigate to the login page
And I enter the following login details:
| username | password |
| cukey | passwoid |
And I click the login button
Then I should land on the newest page
这是我的步骤定义：

public class MaStepdefs extends BaseUtil
private BaseUtil base;
public MaStepdefs(BaseUtil base)
this.base = base;
@And("^I click the login button$")
public void iClickTheLoginButton() throws Throwable
LoginPageObjeks page = new LoginPageObjeks(base.Driver);
page.ClickLogin();
@Given("^I navigate to the login page$")
public void iNavigateToTheLoginPage() throws Throwable
base.Driver.navigate().to("http://www.executeautomation.com/demosite/Login.html");
@And("^I enter the following login details:$")
public void iEnterTheFollowingLoginDetails(DataTable table) throws Throwable
List<User> users = new ArrayList<User>();
users = table.asList(User.class);
LoginPageObjeks page = new LoginPageObjeks(base.Driver);
for (User user : users)
page.Login(user.username, user.password);
//base.Driver.findElement(By.name("UserName")).sendKeys(user.username);
//base.Driver.findElement(By.name("Password")).sendKeys(user.password);
Thread.sleep(2000);
@Then("^I should land on the newest page$")
public void iShouldLandOnTheNewestPage () throws Throwable
Assert.assertEquals("It's not displayed", base.Driver.findElement(By.id("Initial")).isDisplayed(), true);
class User
public String username;
public String password;
public User(String userName, String passWord)
username = userName;
password = passWord;

这是我的 TestRunner：
package Runner;
import cucumber.api.CucumberOptions;
import org.junit.runner.RunWith;
import cucumber.api.junit.Cucumber;
@RunWith(Cucumber.class)
@CucumberOptions(features = "src/test/java/features", glue = "Steps")
public class TestRunner
我不确定数据表类型是什么或如何注册？我试过搞乱 DataTableType 和 TypeRegistry 但我不是专家。任何帮助将不胜感激，谢谢
【问题讨论】：
数据表导入为“import io.cucumber.datatable.DataTable;”而不是你使用的是来自旧版本的黄瓜，比如版本 2。你应该查看 maven 依赖项并清理它。 刚刚试过这个。给了我一个新的错误——io.cucumber.datatable.UndefinedDataTableTypeException: Can't convert DataTable to List您使用的是过时的版本，现在是：
import io.cucumber.datatable.DataTable;
黄瓜 jvm 见 CHANGELOG，引用：
[核心] 用 io.cucumber.datatable.DataTable 替换 DataTable（#1248 M.P. Korstanje，Björn Rasmusson，Marit van Dijk） 可以通过实现 TypeRegistryConfigurer 来定义自定义数据表类型。
现在的使用方式略有不同，例如：
小黄瓜步骤示例：
And I update ADDRESS tab data in building form
| Input | Value |
| Building name | New name |
| Ref | Some ref |
步骤实施：
@And("^some test step$")
public void someTestStep(DataTable table)
List<List<String>> data = table.asLists(String.class);
String buildingName = data.get(1).get(1);
String reference = data.get(2).get(1);
【讨论】：
好的，谢谢。您能否向我展示一个如何修复上述步骤定义的示例？用于输入登录详细信息？ 我尝试了新格式，但它阻止了它下面的“for（用户用户：用户）”行 可能是因为我发布了字符串列表的示例，而不是您在问题中所做的用户。 不，我将其更改为用户，但仍然没有运气 尝试根据从表中检索到的变量“手动”创建用户，就像我一样，作为字符串，并使用这两个检索到的字符串来创建用户，并将其插入用户列表中。如果您在任何地方都使用正确的类型，那么说它破坏“for (User user : users)”是没有意义的。您现在可能想将代码粘贴到 pastebin 上，我会对其进行审核。【参考方案2】： I have created a code which will not use **DataTable** concept. You can update this below implementation so that you will not have any failures in your scripts in future.
CucumberUtil.java:
-----------------
import java.util.HashMap;
import java.util.List;
import java.util.Map;
public class CucumberUtil
// public static synchronized Map<String, String> TableDictionaryConverter(DataTable table) -- removed this concept because of version issues in DataTable
public static synchronized Map<String, String> TableDictionaryConverter(List<List<String>> data)
Map<String, String> mapTable = new HashMap<String, String>();
for(List<String> rows: data)
mapTable.put(rows.get(0), rows.get(1));
return mapTable;
feature:
-------
And I enter the following login details:
| username | cukey |
| password | passwoid |
step defn:
---------
@And("^I enter the following login details:$")
public void iEnterTheFollowingLoginDetails(List<List<String>> table) throws Throwable
Map<String, String> mapTable = CucumberUtil.TableDictionaryConverter(table);
LoginPageObjeks page = new LoginPageObjeks(base.Driver);
page.Login(mapTable.get("username"), mapTable.get("password"));
Thread.sleep(2000);
