我正在使用 WebDriverIO 练习 CucumberJS 并测试 http://webdriver.io 。我有以下功能文件和步骤定义，这工作正常。
特征文件
Feature: Application Title
Page title should be context sensitive
Scenario: Page loads with correct title
When Page "/" is loaded
Then Page title is "WebdriverIO - WebDriver bindings for Node.js"
步骤定义
const { Given, When, Then } = require('cucumber');
const assert = require('assert');
const webdriverio = require('webdriverio');
When(/^Page \"(.*)\" is loaded$/, (page) => {
browser.url(page);
});
Then(/^Page title is \"(.*)\"$/, (title) => {
assert(browser.title(), title);
});
但是当我将 Scenario 更改为 Scenario Outline 时，它停止工作并出现错误。以下是我在功能文件中所做的更改。
功能文件(更新)
Feature: Application Title
Page title should be context sensitive
Scenario Outline: Page loads with correct title
When Page "<url>" is loaded
Then Page title is "<title>"
Examples:
| url | title |
| / | WebdriverIO - WebDriver bindings for Node.js |
| /guide.html | WebdriverIO - Developer Guide |

代码在 GitHub 上可用: https://github.com/mabilalmirza/webdriverio-cucumberjs 。
我做错了什么还是这与CucumberJS有关？
最佳答案
目前看来，这个功能被窃听了。您可以在 wdio-cucumber-framework GitHub 页面上跟踪问题:Here
我花了一整天的时间尝试解决方法，但我想我们只需要等待修复即可。
关于cucumber - 场景大纲不适用于 CucumberJS，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/49691707/
