angularjs - Protractor 和 appium - 无法读取未定义的属性

Question

我正在尝试在 Android 设备上进行一些 Selenium 测试。所有连接接缝均正常工作，因为在设备上我可以看到 chrome 打开，然后 url 更改为数据；

但网址更改后，一切都停止了

[launcher] Error: TypeError: Cannot read property 'Q' of undefined at module.exports (C:\src\angular-test\node_modules\wd-bridge\lib\wd-bridge.js:6:13)

我认为它与wdBridge有关，好像我检查wd-bridge，js，Q看起来像这样:

var Q = wd.Q;

我不知道为什么它不起作用。

我的 Protractor 配置文件如下:

"use strict";

exports.config = {
    specs: ['e2e/*.js'],
    framework: 'jasmine',
    capabilities: {
        'appium-version': '',
        'platformName': 'Android',
        'platformVersion': '6.0',
        'deviceName': 'Android Device',
        'autoWebView': true,
        'app': "C:/src/angular-test/platforms/android/build/outputs/apk/android-debug.apk",
        'udid': '',
        'fullReset': true,
        'browserName': 'chrome'
    },
    jasmineNodeOpts: {
        showColors: true,
        defaultTimeoutInterval: 30000,
        print: function () {
        }
    },
    onPrepare: function () {

        var DisplayProcessor = require('../node_modules/jasmine-spec-reporter/src/display-processor');
        var SpecReporter = require('jasmine-spec-reporter');

        function TimeProcessor(options) {
        }

        function getTime() {
            var now = new Date();
            return now.getHours() + ':' +
                now.getMinutes() + ':' +
                now.getSeconds()
        }

        TimeProcessor.prototype = new DisplayProcessor();
        TimeProcessor.prototype.displaySuite = function (suite, log) {
            return getTime() + ' - ' + log;
        };
        TimeProcessor.prototype.displaySuccessfulSpec = function (spec, log) {
            return getTime() + ' - ' + log;
        };
        TimeProcessor.prototype.displayFailedSpec = function (spec, log) {
            return getTime() + ' - ' + log;
        };
        TimeProcessor.prototype.displayPendingSpec = function (spec, log) {
            return getTime() + ' - ' + log;
        };

        // add jasmine spec reporter
        var reporter = new SpecReporter({
            customProcessors: [TimeProcessor]
        });

        jasmine.getEnv().addReporter(reporter);

        var wd = require('wd'),
            wdBridge = require('wd-bridge')(wd);
        wdBridge.initFromProtractor(exports.config);

    },
    //seleniumAddress: 'http://localhost:4723/wd/hub' //For mobile devices
    seleniumAddress: 'http://localhost:4444/wd/hub' //For desktop
};

一如既往，我们非常感谢任何帮助。谢谢

我自己设法解决了这个问题。这就是我所做的:

从上面的代码开始，如上所述，Q 是未定义的。这是因为可以在节点模块文件夹内的 wd-bridge.js 文件中找到的 var Q = wd.Q 位于需要 2 个参数的函数内。

我像这样更改了 protractor.config.js 文件:

"use strict";

var wd = require('wd');
var protractor = require ('protractor');
var wdBridge = require('wd-bridge')(protractor,wd);

exports.config = {
    specs: ['e2e/*.js'],
    framework: 'jasmine',
    capabilities: {
        'appium-version': '',
        'platformName': 'Android',
        'platformVersion': '6.0',
        'deviceName': 'Android Device',
        'autoWebView': true,
        'app': "C:/src/angular-test/platforms/android/build/outputs/apk/android-debug.apk",
        'udid': '',
        'fullReset': true,
        'browserName': 'chrome'
    },
    jasmineNodeOpts: {
        showColors: true,
        defaultTimeoutInterval: 30000,
        print: function () {
        }
    },
    onPrepare: function () {

        var DisplayProcessor = require('../node_modules/jasmine-spec-reporter/src/display-processor');
        var SpecReporter = require('jasmine-spec-reporter');

        function TimeProcessor(options) {
        }

        function getTime() {
            var now = new Date();
            return now.getHours() + ':' +
                now.getMinutes() + ':' +
                now.getSeconds()
        }

        TimeProcessor.prototype = new DisplayProcessor();
        TimeProcessor.prototype.displaySuite = function (suite, log) {
            return getTime() + ' - ' + log;
        };
        TimeProcessor.prototype.displaySuccessfulSpec = function (spec, log) {
            return getTime() + ' - ' + log;
        };
        TimeProcessor.prototype.displayFailedSpec = function (spec, log) {
            return getTime() + ' - ' + log;
        };
        TimeProcessor.prototype.displayPendingSpec = function (spec, log) {
            return getTime() + ' - ' + log;
        };

        // add jasmine spec reporter
        var reporter = new SpecReporter({
            customProcessors: [TimeProcessor]
        });

        jasmine.getEnv().addReporter(reporter);

        wdBridge.initFromProtractor(exports.config);

    },
    //seleniumAddress: 'http://localhost:4723/wd/hub' //For mobile devices
    seleniumAddress: 'http://localhost:4444/wd/hub' //For desktop
};

现在工作正常。

注意:如果未找到 wd、wdBridge 或 protractor 模块，则无需全局安装它们(对于例如，npm install wd 而不是 npm install -g wd)

希望这可以帮到你。
