var root = 'undefined' == typeof window
  ? self
  : window;

依赖文件路径

jasonborndeMacBook-Air:selenium jasonborn$ ls
chromedriver_2.12.zip
selenium-server-standalone-2.44.0.jar
jasonborndeMacBook-Air:selenium jasonborn$ pwd
/usr/local/lib/node_modules/protractor/selenium

配置文件

// An example configuration file
exports.config = {
  // The address of a running selenium server.
  seleniumAddress: 'http://localhost:4444/wd/hub',
  // Capabilities to be passed to the webdriver instance.
  capabilities: {
    'browserName': 'chrome'
  },
  // Spec patterns are relative to the configuration file location passed
  // to protractor (in this example conf.js).
  // They may include glob patterns.
  specs: ['index.spec.js'],
  directConnect: true,
  // Options to be passed to Jasmine-node.
  jasmineNodeOpts: {
    showColors: true // Use colors in the command line report.
  }
};

测试文件

// spec.js
describe('snowykiss homepage', function() {
  it('should have a title', function() {
    browser.get('http://127.0.0.1:1336/');
    expect(browser.getTitle()).toEqual('web worker');
  });
});

待测试页面必须为完整的angular application，否则会报错。

文件下载

download = document.createElement("A");
download.href = url;
document.body.appendChild(download);
download.click();
setTimeout(function() { download.parentNode.removeChild(download); }, 50);

DEBUG模块使用

var debug = require('debug')('master');
var deviant = require('debug')('master');
// 调整信息输出方法
deviant.log = console.error.bind(console);
deviant('place error default standard output');
// 用以计时亦可
debug('the %s has never change', 'world');
setTimeout(function() {
  debug('the %s has never change', 'human');
}, 200);

# 不清楚具体原理，必须置于最前
DEBUG=* node slavery.js

PHANTOMJS_BIN

OSX下使用karma调用headless浏览器时，需要声明

declare -x PHANTOM_JS='/usr/local/bin/phantomjs';

Jasmine

getJasmineRequireObj().toBeCloseTo = function() {
    function toBeCloseTo() {
        return {
            compare: function(actual, expected, precision) {
                if (precision !== 0) {
                    precision = precision || 2;
                }
                return {
                    pass: Math.abs(expected - actual) < (Math.pow(10, -precision) / 2)
                };
            }
        };
    }
    return toBeCloseTo;
};

angular测试中触发ng-model更新

// version-1
element.val('colorful');
element.trigger($sniffer.hasEvent('input') ? 'input' : 'change');
// version-2
ngModelController = el.find('input').controller('ngModel');
ngModelController.$setViewValue('test');
