CucumberJS脚本错误

Question

我是cucumber新手，所以我不知道我的问题是因为缺乏理解，还是因为脚本的错误(不太可能是我认为的那样)。所以，我只想说说发生了什么。通常，当我运行cucumber时，我会得到特性/场景输出，但是脚本稍后会在执行过程中抛出错误。我读到这可能是由我的feature或steps_definition文件中的错误引起的，但我不知道该查找什么。

我将包安装为依赖项。

  "dependencies": {
    "cucumber": "^4.0.0",
    "react": "^16.3.0-alpha.1",
    "react-native": "0.54.1",
    "react-native-cli": "^2.0.1"
  }

并在我的scripts对象中设置

  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "jest": "jest",
    "cucumber": "cucumber-js",
    "gjest": "gherkin-jest",
    "jestc": "jest-cucumber"
  }

我的功能文件(位于/features中)是这样的：

Feature: Create a new member account
  As a new member
  I want to create a member account

Scenario: Create a new user
  When I create a new user with details:
    | Username | mstelly              |
    | Email    | my.email@example.com |
    | Password | mySecretPassword     |
  Then the user is created successfully

我的step_definitions文件(位于/features/step_definitions中)如下：

    const { Given, Then, When } = require('cucumber');
    const expect = require('expect');

    When('I create a new user with details:', function(table) {
      const data = table.rowsHash();
      JSON.stringify(data);
    });

    Then('the user is created successfully', function() {
      // Write code here that turns the phrase above into concrete actions
      return 'pending';
    });

当我执行脚本：npm run cucumber features -r step_definitions/时，我收到以下控制台输出：

> mobile_gtm@0.0.1 cucumber /Users/michaelstelly/Documents/projects/mobile_gtm
> cucumber-js "features" "step_definitions/"

.P

这就是我掌握的全部信息。我收到黄瓜输出，然后得到npm错误。他们可能与黄瓜无关，但在这一点上，我不能肯定。

我们很感激你的帮助。如果你有问题，请问。

我想这是应该发生的。https://github.com/cucumber/cucumber-js/issues/843#issuecomment-305331023

如果存在任何未定义/挂起/失败/不明确的步骤，则退出状态为1的黄瓜-js。如果所有步骤都通过，则退出状态为0。

我知道这个问题很古老，但是我偶然发现了这个问题的答案，希望它能帮助我的未来。
