Question

我是java脚本量角器黄瓜框架的新手。

我可以在一年前看到类似的问题，但这也是在一年前的量角器版本中修复的。因此提出了一个新问题。

我正在使用最新版本的黄瓜，量角器，量角器 - 黄瓜 - 框架，chai，chai-as-promise。我使用visual studio代码作为编辑器。节点版本是6.11.4。有关所有版本的详细信息，请查看下面的package.json。

当我执行我的测试时，它会在不到一秒的时间内完成传递结果，但它只是启动浏览器然后在浏览器中没有做任何事情。

请查看我正在使用的文件，并建议我问题出在哪里。我不确定这是否是最新版本的量角器中的总线。

protractor.conf.js：

exports.config = {  
    seleniumAddress: 'http://localhost:4444/wd/hub',  
    specs: ['features/*.feature'],  
    getPageTimeout: 60000,
    allScriptsTimeout: 500000,
    baseURL: 'http://www.protractortest.org/testapp/ng1/#/form',
    framework: 'custom',
    frameworkPath: require.resolve('protractor-cucumber-framework'),
    capabilities: {
      'browserName': 'chrome'
    },
    cucumberOpts: {
      require: [ './features/step_definitions/*.steps.js' ],
      tags: false,
      profile: false,
      'no-source': true
    }
};

test.feature：

Feature: Running Cucumber with Protractor
    As a user of Protractor
    I should be able to use Cucumber
    In order to run my E2E tests

    Scenario: Login to myApp
        Given I go to Login page
        When I login with "username" and "pwd"
        Then "You are logged in as ADMIN" is displayed

test.steps.js：

var chai = require('chai');
var chaiAsPromised = require('chai-as-promised');
var {defineSupportCode} = require('cucumber');
var expect = chai.expect;
chai.use(chaiAsPromised);
defineSupportCode(function({Given, When, Then}) {
    Given('I go to DSH Login page', function () {
        browser.get("http://localhost/myapp");
        expect(element(by.buttonText('Login')).isDisplayed()).to.eventually.equal(true);
    });
    When('I login with {string} and {string}', function (username, password) {
        element(by.id('username')).sendKeys(username);
        element(by.id('password')).sendKeys(password);
        element(by.buttonText('Login')).click();
    });
    Then('{string} is displayed', function (headerText) {
        expect(element(by.cssContainingText('ng-isolate-scope', headerText)).isDisplayed()).to.eventually.equal(true);
    });
});

Answer 1

您可以尝试使用回调参数而不是依赖承诺。如果有效，那么输入用户名＆amp;密码，你可以使用Q包来解决所有的承诺。

var chai = require('chai');
var chaiAsPromised = require('chai-as-promised');
var {defineSupportCode} = require('cucumber');
var expect = chai.expect;
chai.use(chaiAsPromised);
defineSupportCode(function({Given, When, Then}) {
    Given('I go to DSH Login page', function (callback) {
        browser.get("http://localhost/myapp");
        expect(element(by.buttonText('Login')).isDisplayed()).to.eventually.equal(true).and.notify(callback);
    });
    When('I login with {string} and {string}', function (username, password, callback) {
        element(by.id('username')).sendKeys(username);
        element(by.id('password')).sendKeys(password);
        element(by.buttonText('Login')).click().then(function() {
            callback();
        });
    });
    Then('{string} is displayed', function (headerText, callback) {
        expect(element(by.cssContainingText('ng-isolate-scope', headerText)).isDisplayed()).to.eventually.equal(true).notify(callback);
    });
});

Answer 2

由于我已经习惯了Javascript，我想我会发布我目前正在做的事情。

我已停止使用回调。相反，我使用async和await，以便控件等待异步操作完成。

例如：

When('I login with {string} and {string}', async function (username, password) {
    await element(by.id('username')).sendKeys(username);
    await element(by.id('password')).sendKeys(password);
    await element(by.buttonText('Login')).click();
});

希望这有助于某人。

量角器测试正在通过，但没有执行测试
