如何将屏幕截图附加到量角器的 HTML 报告?

How to attach screenshot to protractor's HTML report?

在我的 protractor 项目中,我正在尝试截取屏幕截图,并将其附加到我的 html 报告中。截图的过程发生在Afterhook中,如下:

import {  Status,After, HookScenarioResult} from 'cucumber';
import {browser} from 'protractor';
import { async } from 'q';

After(async  (scenario:HookScenarioResult)=> {

    if(scenario.result.status===Status.FAILED){
        const screenshot = await browser.takeScreenshot();
        this.attach(screenshot,"image/png");
    }
});

但在行 this.attach(screenshot,"image/png"); 中,它抱怨:

TypeError: this.attach is not a function

什么问题?

我的配置是:

   "cucumber": "^5.1.0",
    "cucumber-html-reporter": "^4.0.4",
    "protractor": "^5.4.2",
    "protractor-cucumber-framework": "^6.1.1",

问题已解决,将 fat 功能更改为普通功能。我仍然不明白为什么它会影响我的代码,但现在运行良好,并且我的 html 报告中有屏幕截图。

After(async function(scenario) {
    if (scenario.result.status === Status.FAILED) {
        // screenShot is a base-64 encoded PNG
            const screenShot = await browser.takeScreenshot();
            this.attach(screenShot, "image/png");
    }
});

尝试以下适合我的代码:

  After(function(scenarioResult) {
    let self = this;
    if (scenarioResult.result.status === Status.FAILED) {
    return browser.takeScreenshot()
    .then(function (screenshot) {
        const decodedImage = new Buffer(screenshot.replace(/^data:image\/png;base64,/, ''), 'base64');
        self.attach(decodedImage, 'image/png');
    });
}
});
