Docker中的量角测试 - 异步回调未在Jasmine.default_timeout_interval指定的超时中调

Question

我使用了我的Angular2应用程序编写了6个E2E测试。测试在我的Windows 10系统上正常运行。测试是一致的，并且一直通过。

现在，我试图在Centos Docker容器中运行相同的测试。测试不一致。他们一直失败。

我有一个错误说

错误：超时 - 在jasmine.default_timeout_interval指定的超时中未调用async回调。

我已经增加了时间，我给了浏览器。在所需的位置给予(直到存在(，我增加了分配给Docker的计算资源(CPU-3，Memory-3328MB(。似乎没有任何效果。

 // Protractor configuration file, see link for more information  
const { SpecReporter } = require('jasmine-spec-reporter');
exports.config = {
  allScriptsTimeout: 11000,
  specs: [
    './e2e/**/*.e2e-spec.ts'
  ],
  capabilities: {
    'browserName': 'chrome',
    'chromeOptions': {
      'args': [ '--no-sandbox']
    }
  },
  directConnect: false,
  baseUrl: 'http://localhost:3200/',
  framework: 'jasmine2',
  jasmineNodeOpts: {
    showColors: true,
    defaultTimeoutInterval: 30000,
    print: function() {
      // NOOP
    }
  },
  beforeLaunch: function() {
    require('ts-node').register({
      project: 'e2e/tsconfig.e2e.json'
    });
  },
  onPrepare() {
    browser.driver.manage().window().maximize();
    jasmine.getEnv().addReporter(new SpecReporter({ spec: { displayStacktrace: true } }));
  }
};

测试之一

// create a user and he should be able to login after creation
  it('should add a new user and log him in successfully', () => {
    browser.wait(until.presenceOf(userCreate.forename, 5000, 'Timed out'));
    const forename = 'newUserFore' + generateRandom.generateRandom();
    const surename = 'newUserSur' + generateRandom.generateRandom();
    const username = 'newUserUser2' + generateRandom.generateRandom();
    const password = 'Pass@123' + generateRandom.generateRandom();
    userCreate.addUserWithPassword(forename, surename, username, password);
    // select language
    userCreate.selectDropdownByNumber(userCreate.mylang, 1);
    // select role
    userCreate.selectDropdownByNumber(userCreate.myrole, 1);
    // click add
    userCreate.addUserButton.click();
    browser.wait(until.presenceOf(userCreate.successMessage, 5000, 'Timed out'));
    expect(userCreate.successMessage.getText()).toContain('User saved successfully!');
    // cancelbutton
    userCreate.cancelbutton.click();
    browser.wait(until.presenceOf(userOverview.addUserButton, 5000, 'Timed out'));
    // logout
    indexPage = homePage.menu.navigateTo(MenuOption.LOGOUT, until);
    // click on login button on first page
    loginPage = indexPage.loginButtonClickedOnBasePage();
    // login with the credentials
    browser.wait(until.presenceOf(loginPage.loginTitle, 5000, 'Timed out'));
    loginPage.login(username, password);
    browser.wait(until.presenceOf(menu, 5000, 'Timed out'));
    expect(menu.isDisplayed()).toBe(true);
  });

功能测试文件，我首先启动服务器，然后运行UI

     #!/usr/bin/env bash
    echo  "API: Ensuring the port $API_SERVER_PORT is freed."
    fuser -k -n tcp $API_SERVER_PORT

    echo " Starting the server in detached mode. This will take about 5 minutes the first time  "
    cd ../api && mvn spring-boot:run  -D server.port=$API_SERVER_PORT >> api-start.log 2>&1 &
    # Wait for the server to come up..
    while ! (ncat -w 1 127.0.0.1 $API_SERVER_PORT </dev/null >/dev/null 2>&1); do sleep 1; done
    echo "Server started on port $API_SERVER_PORT"

    echo "UI: Ensuring the port $UI_SERVER_PORT is freed."
    fuser -k -n tcp $UI_SERVER_PORT
    npm start >> ui-start.log 2>&1 &
    while ! (ncat -w 1 127.0.0.1 $UI_SERVER_PORT </dev/null >/dev/null 2>&1); do sleep 1; done
    echo "Angular app is running on port $UI_SERVER_PORT , startup logs is in start.log".

您是否尝试过将主机的/dev/shm安装到容器上？

这显然是已知的解决方法，可以阻止硒与Chrome或Firefox在Docker中坠毁。硒崩溃并不明显，它只是通过茉莉超时表示。
