问题描述
尝试使用Cucumber / Selenium / java / intelliJ运行方案，但是在其中一个步骤中遇到有关DataTable的错误。在我开始使用测试运行程序并更改了一些内容之前，dataTable正常运行并正确转换了该步骤的参数，但我无法使其正常工作。
Trying to run a scenario with cucumber/selenium/java/intelliJ, but getting an error regarding the DataTable in one of the steps. The dataTable was working fine and converting the arguments for the step correctly before I started using a test runner and changed some things around, but I just can't get this to work.
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.

这是我的情况：
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：
package Steps;
import Base.BaseUtil;
import Pages.LoginPageObjeks;
import cucumber.api.DataTable;
import cucumber.api.PendingException;
import cucumber.api.java.en.And;
import cucumber.api.java.en.Given;
import cucumber.api.java.en.Then;
import io.github.bonigarcia.wdm.WebDriverManager;
import org.junit.Assert;
import org.openqa.selenium.By;
import org.openqa.selenium.chrome.ChromeDriver;
import java.util.ArrayList;
import java.util.List;
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：
And here's my TestRunner:

import cucumber.api.junit.Cucumber;
@RunWith(Cucumber.class)
@CucumberOptions(features = {"src/test/java/features"}, glue = "Steps")
public class TestRunner {
}
我不确定数据表的类型是如何注册一个？我曾尝试弄乱DataTableType和TypeRegistry，但我不是专家。任何帮助将不胜感激，谢谢
I'm not sure what a data table type is or how to register one? I've tried messing around with DataTableType and TypeRegistry but I'm not an expert. Any help would be appreciated, thanks
推荐答案
您正在使用过时的版本，现在是：
You are using outdated version, it is now:
import io.cucumber.datatable.DataTable;
请参见 CHANGELOG 用于黄瓜jvm，引用：
See CHANGELOG for cucumber jvm, quote:
[Core]替换带有io.cucumber.datatable.DataTable的DataTable（＃1248 MP Korstanje，BjörnRasmusson，Marit van Dijk）
可以通过实现TypeRegistryConfigurer来定义自定义数据表类型。
[Core] Replace DataTable with io.cucumber.datatable.DataTable (#1248 M.P. Korstanje, Björn Rasmusson, Marit van Dijk) Custom data table types can be defined by implementing the TypeRegistryConfigurer.
现在使用它的方式略有不同，例如：
There is slightly different way of using it now, example:
小黄瓜步骤：
Sample gherkin step:
And I update ADDRESS tab data in building form
| Input | Value |
| Building name | New name |
| Ref | Some ref |
步骤实现：
Step implementation:
@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);
}
