Question

我遇到了量角器图像比较，并想对其进行测试。

我基于example of the website进行了有限测试，但出现错误

失败：无法读取未定义的属性'saveFullPageScreen'。

browser.imageComparison未定义。
奇怪的是我在示例后收到此错误。对量角器的支持有限，所以我在这里询问。

----------------- test.spec.ts --------------
import { browser, } from 'protractor';
import { Urls,  DashboardPage } from '../utils';

fdescribe('protractor-image-comparison desktop', () => {
  beforeEach(async () => {
    await Urls.gotoDashboard();
    await DashboardPage.getVPoints();
  //  await DashboardPage.removeDebugInfo();
  });

it('should save some screenshots', async() => {
  // Save a full page screens
   await  .saveFullPageScreen('fullPage', { /* some options*/ });
   });
it('should compare successful with a baseline', async() => {
   // Check a full page screens
   expect(await browser.imageComparison.checkFullPageScreen('fullPage', { /* some options*/ })).toEqual(0);
   });
});

-------------- part of jasmine.ts ---------------
plugins: [
        {
            // The module name
            package: 'protractor-image-comparison',
            // Some options, see the docs for more
            options: {
                baselineFolder: join(process.cwd(), './baseline/'),
                formatImageName: `{tag}-{logName}-{width}x{height}`,
                screenshotPath: join(process.cwd(), '.tmp/'),
                savePerInstance: true,
                autoSaveBaseline: true,
                blockOutToolBar: true,
                clearRuntimeFolder: true,
                // ... more options
            },
        },
    ],

失败：

根据文档，您在browser.imageComparison之前缺少.saveFullPageScreen
