我正在使用量角器 - 黄瓜框架，无法运行我的测试。浏览器已启动但未导航到我的URL，然后收到以下错误：
exports.config = {
seleniumAddress: 'http://127.0.0.1:4444/wd/hub',
//// getPageTimeout: 60000,
////allScriptsTimeout: 500000,
framework: 'custom',

},
// Spec patterns are relative to this directory.

cucumberOpts: {
require: 'Features/step_definitions/homePage.js',

}
};
Conf.js
#features/test.feature
Feature: App hub home page
Scenario: First sample
Given I go to the app hub site
When the homepage has loaded
Then I expect to see title app hub
功能文件：
module.exports = function() {
this.Given('I go to the app hub site', function (callback) {
browser.get('http://localhost:8080')
.then (callback);
});
};
步骤定义：
目前我只为声明提供步骤定义“鉴于我转到应用中心网站”
step_definitions保存在我在conf.js文件中引用的'Features'文件夹中名为'step_definitions'的文件夹中。

非常感谢任何帮助。

这是错误很可能是因为你正在使用带有量角器 - 黄瓜 - 框架的黄瓜2.0。目前它们是不兼容的，请将您的黄瓜版本降级到1.3.1，这应该可以解决您的问题。
与此同时，正在利用量角器 - 黄瓜 - 框架支持黄瓜2.0取得了良好的进展。您可以查看此repo- protractor-cucumber-frameowrk了解更多详情。

可能是不匹配的软件包版本导致了问题。当你运行npm list <package-name>时你会得到什么？
我目前在package.json中有以下内容：
"devDependencies": {
"chai": "^3.5.0",
"chai-as-promised": "^5.3.0",
"chai-string": "^1.2.0",
"cucumber": "^1.0.0",
"gulp": "^3.9.1",
"gulp-angular-protractor": "^0.1.1",
"protractor": "^3.3.0",
"protractor-cucumber-framework": "^0.6.0"
},
有了这个，我正在使用这些版本而没有任何麻烦：

太好了，谢谢你的帮助。我正在使用黄瓜2.0。我在量角器网站上找到了一个解决方法，并更改了我的config.js文件，因此frameworkPath现在引用了index.js文件，这很有效。
<强> Config.js
/protractor.conf.js
exports.config = {
seleniumAddress: 'http://127.0.0.1:4444/wd/hub',

这是我的index.js文件
<强> index.js `
var q = require('q'),

* @return {q.Promise} Promise resolved with the test results
*/
exports.run = function(runner, specs) {
var results = {};
return runner.runTestPreparer().then(function() {
var config = runner.getConfig();
var opts = assign({}, config.cucumberOpts, config.capabilities.cucumberOpts);
state.initialize(runner, results, opts.strict);
return q.promise(function(resolve, reject) {
var cliArguments = convertOptionsToCliArguments(opts);
cliArguments.push('--require', path.resolve(__dirname, 'lib', 'resultsCapturer.js'));
cliArguments = cliArguments.concat(specs);
debug('cucumber command: "' + cliArguments.join(' ') + '"');
Cucumber.Cli(cliArguments).run(function (isSuccessful) {
try {
var complete = q();
if (runner.getConfig().onComplete) {
complete = q(runner.getConfig().onComplete());
}
complete.then(function() {
resolve(results);
});
} catch (err) {
reject(err);
}
});
});
});
function convertOptionsToCliArguments(options) {
var cliArguments = ['node', 'cucumberjs'];
for (var option in options) {
var cliArgumentValues = convertOptionValueToCliValues(option, options[option]);
if (Array.isArray(cliArgumentValues)) {
cliArgumentValues.forEach(function (value) {
cliArguments.push('--' + option, value);
});
} else if (cliArgumentValues) {
cliArguments.push('--' + option);
}
}
return cliArguments;
}
function convertRequireOptionValuesToCliValues(values) {
var configDir = runner.getConfig().configDir;
return toArray(values).map(function(path) {
// Handle glob matching
return glob.sync(path, {cwd: configDir});
}).reduce(function(opts, globPaths) {
// Combine paths into flattened array
return opts.concat(globPaths);
}, []).map(function(requirePath) {
// Resolve require absolute path
return path.resolve(configDir, requirePath);
}).filter(function(item, pos, orig) {
// Make sure requires are unique
return orig.indexOf(item) == pos;
});
}
function convertGenericOptionValuesToCliValues(values) {
if (values === true || !values) {
return values;
} else {
return toArray(values);
}
}
function convertOptionValueToCliValues(option, values) {
if (option === 'require') {
return convertRequireOptionValuesToCliValues(values);
} else {
return convertGenericOptionValuesToCliValues(values);
}
}
function toArray(values) {
return Array.isArray(values) ? values : [values];
}};
这不是一个解决方案，但是一种解决方法，使我能够成功运行我的测试。
