在 Azure DevOps 管道中运行时，Angular/Protractor E2E 测试失败。 本地通过

Question

I am trying to run e2e tests on my angular application. My tests pass locally when I run ng e2e but not in my pipeline. I'm going to share my protractor.conf, the pipeline tasks and the output I get from the task that fails below.

Some more background:

• I am trying to run e2e code from an otherwise empty angular app. The test I am trying to run simply logs into AD by navigating to my website, entering a username/ password and then checking the that the user is redirected to my website.
• I am running this from a release pipeline where the repo containing the e2e tests is added as an artifact.
• I am using xpaths to find elements on the page
• I've omitted my jasmine code because I do not think it is relevant since the tests pass locally. However, if I'm wrong on this point let me know and I will post it.

protractor.conf.js

const { SpecReporter } = require('jasmine-spec-reporter');

process.env.CHROME_BIN = process.env.CHROME_BIN || require("puppeteer").executablePath();

exports.config = {
  allScriptsTimeout: 11000,
  specs: [
    './src/**/*.e2e-spec.ts'
  ],
  capabilities: {
    chromeOptions: {
      args: ["--headless", "--disable-gpu", "--window-size=1200,900"],
      binary: process.env.CHROME_BIN
    },
    'browserName': 'chrome'
  },
  directConnect: true,
  baseUrl: 'http://localhost:4200/',
  framework: 'jasmine',
  jasmineNodeOpts: {
    showColors: true,
    defaultTimeoutInterval: 120000,
    print: function() {}
  },
  onPrepare() {
    require('ts-node').register({
      project: require('path').join(__dirname, './tsconfig.e2e.json')
    });
    jasmine.getEnv().addReporter(new SpecReporter({ spec: { displayStacktrace: true } }));
  }
};

Failed Task Output:

Please help me get these tests to pass in azure

Thanks!

EDIT: I have that 'Update Webdriver' task because I read I should do it somewhere, it doesn't actually change the outcome if it is there or not

Answer 1

Have you tried to increase your allScriptsTimeout ?

The timeout in milliseconds for each script run on the browser. This should be longer than the maximum time your application needs to stabilize between tasks.
