javascript - 实习生 cucumber 插件错误: A plugin named "cucumber" has not been registered

Question

我正在尝试让 intern-cucumber 插件正常工作。我收到以下错误:

Error: A plugin named "cucumber" has not been registered
  at Node.BaseExecutor.getPlugin @ src\lib\executors\Executor.ts:387:12
  @ tests\addition.js:6:29
  at runFactory @ node_modules\dojo\dojo.js:1134:43

  @ src\lib\executors\Node.ts:882:24
  @ node_modules\@theintern\common\index.js:16:7174

关于如何解决这个问题有什么想法吗？我的 intern.json 配置文件如下所示:

{
  "loader": {
    "script": "dojo",
    "options": {
      "packages": [
        {
          "name": "features",
          "location": "features"
        },
        {
          "name": "models",
          "location": "models"
        },
        {
          "name": "dojo", 
          "location":  "node_modules/dojo"
        }
      ]
    }
  },
  "functionalSuites": "tests/**.js",
  "environments": [ "chrome" ],
  "browser": {
    "plugins": [
      "node_modules/intern-cucumber/browser/plugin.js"
    ]
  },
  "node": {
    "plugins": "node_modules/intern-cucumber/plugin.js"
  }

}

我的测试文件，发生错误的地方，addition.js 看起来像:

define([
    'models/calculator',
    'dojo/text!features/addition.feature'
], function (calculator, featureSrc) {

    const cucumber = intern.getPlugin('cucumber');
    const assert = intern.getPlugin('chai').assert; 

    cucumber.registerCucumber('Calculator addition', featureSrc, function () {

        cucumber.Given('the calculator is cleared', function () {

        });

        cucumber.When(/^I add (\d+) and (\d+)$/, function (x, y) {
            var calc = new Calculator(x, y)

        })

        cucumber.Then(/^the result should be (\d+)$/, function (z) {
            var result = calc.sum();
            assert.equal(z,result,'Expected result to be: ' + z)
        })
    }

    )
}

)

有人知道如何解决这个问题吗？不知道为什么该插件无法工作，我的 intern.json 文件有问题吗？

Answer 1

代码正在调用intern.getPlugin('cucumber')。它实际上应该调用 intern.getPlugin('interface.cucumber') 或 intern.getInterface('cucumber') (前者是首选)。

Intern 有一个专门用于注册和检索接口(interface)的 API(registerInterface 和 getInterface)。然而，它只是通用插件 API(registerPlugin 和 getPlugin)的一个薄包装，它将 interface. 添加到插件名称中。接口(interface) API 将来可能会被删除，而只使用单个插件 API。
