使用量角器“期望”

Question

我有一些按顺序运行的简单规范。第一个具有网页标题的expect 断言 - 第二个也是如此。

但是，当我运行序列时，第一个断言通过但第二个断言失败，并且 console.log 显示第一个规范的 expect 的部分已与第二个规范的 expect 合并。

我觉得这与 promise 有关...请有人证实这一点（或否认它！！）并建议如何完成承诺？

谢谢

第一个规范

describe('JL Homepage', function() {
//browser.waitForAngularEnabled(false);
browser.get('https://mwac-johnlewis-dev.digitalbridge.eu/landing');

 browser.sleep(10000);


it('should have a title', function(){
expect (browser.getTitle()).toBe('John Lewis Wallpaper Visualiser: 
Welcome');
});

});

第二规范

describe('Demo photo', function() {
browser.waitForAngularEnabled(false);


browser.sleep(3000);
element(by.xpath('html/body/webapp-app/div/div/webapp-johnlewis-landing/div/div/ul/li[2]/a/span')).click();

it('should load a demo room', function(){

    expect (browser.getTitle()).toEqual('John Lewis Wallpaper Visualiser: Design your room');

browser.sleep(3000);
});

});

您需要将所有操作包装在有效的 Jasmine 块中。

找到an introduction of Jasmine with examples here 和latest API description here。

作为补充： browser.get() 总是有点难以处理，因为 Protractor 无法知道要加载的页面是否包含 Angular。因此，在页面完全加载之前，测试执行可以继续。

为防止执行过快，请使用ExpectedConditions 和browser.wait()

在这里，我建议第一个规范是：

describe('JL Homepage', function() {
    //possibility for beforeAll(), beforeEach(), afterAll(), afterEach()
    it('should load the page and have a title', function(){
        var EC = protractor.ExpectedConditions;
        browser.get('https://mwac-johnlewis-dev.digitalbridge.eu/landing');
        //wait until URL has changed
        browser.wait(EC.urlIs('https://mwac-johnlewis-dev.digitalbridge.eu/landing'),5000);
        //wait until page has finished loading
        browser.waitForAngular();
        expect (browser.getTitle()).toBe('John Lewis Wallpaper Visualiser: Welcome');
    });
});
