问题:

I developed the Tour of Heroes Angular tutorial application. After that I wrote tests for the components. The application and the component tests are doing fine. Now I wanted to develop E2E tests with Protractor and I can't get them running.

Every time I run ng e2e on the command line, I get the following output:

$ ng e2e

Some hopefully useful information regarding my setup:

  • The project was created with the Anguliar CLI
  • Protractor was installed globally and local
  • The following files are in the node_modules/webdriver-manager/selenium directory: chromedriver_2.32.exe, chromedriver_2.32.zip, chrome-response.xml, gecko-response.json, selenium-server-standalone-3.5.3.jar, standalone-response.xml
  • I run webdriver-manager update with a proxy property
  • It makes no difference if I run the command with a running Selenium Grid or with the directConnect: true configuration
  • As browser is set Chrome (Firefox has the same problem)
  • OS: Windows 10, Browser: Chrome 51.0.2704.106 m (64-bit)

protractor.conf.js file:

// Protractor configuration file, see link for more information
// https://github.com/angular/protractor/blob/master/lib/config.ts

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

exports.config = {
  allScriptsTimeout: 11000,
  specs: [
    './e2e/**/*.e2e-spec.ts'
  ],
  capabilities: {
    'browserName': 'chrome'
  },
  directConnect: true,
  baseUrl: 'http://localhost:4200/',
  /*seleniumAddress: 'http://localhost:4444/wd/hub',*/
  directConnect: true,
  framework: 'jasmine',
  jasmineNodeOpts: {
    showColors: true,
    defaultTimeoutInterval: 30000,
    print: function() {}
  },
  onPrepare() {
    require('ts-node').register({
      project: 'e2e/tsconfig.e2e.json'
    });
    jasmine.getEnv().addReporter(new SpecReporter({ spec: { displayStacktrace: true } }));
  }
};

It's the first time that I try to develop E2E tests with Angular and Protractor.

Thank you for your support!

Update

I didn't know that webdriver-manager update will be executed if I run ng e2e. So I tried ng e2e --no-webdriver-update and with this command the error above is not coming anymore. I think the error appears because no proxy is set and the webdriver-manager is not able to run the update.

However, now I am getting a new error. Here is the full output again:

$ ng e2e --no-webdriver-update

回答1:

OK, I was able to solve the problem. Here is what I did.

ng e2e runs the webdriver-manager update command. In my case this caused the ETIMEDOUT problem, because in my environment without a proxy it cannot download the files. Instead I have to use ng e2e --no-webdriver-update.

Now I had the Could not find update-config.json error.

Using the --proxy argument to update webdriver-manager seems to not download everything and/or correct. I had to set the environment variables HTTP_PROXY and HTTPS_PROXY and run the command webdriver-manager update --ignore_ssl.

Now protractor is working.



回答2:

I found that webdriver-manager update respects HTTPS_PROXY environment variable. Try to setup HTTPS_PROXY environment variable with your (corporate) proxy server http://********:80 Restart your VS Code or command prompt (to pickup changes) and you should be fine to run e2e tests without issues.



回答3:

If you are in webstorm or Intellij editor. You can either setup the HTTPS_PROXY variable or in the webstorm terminal 

SET https_proxy=http://yourcompanydomain.com:portnumber
SET http_proxy=http://yourcompanydomain.com:portnumber

Then run the following command in Terminal 

ng e2e

it should definitely work
