如何在docker-compose中運行量角器測試

Question

我在使用使用docker image的量角器框架進行啟動測試時遇到問題。 當我在本地硒服務器中開始測試時，測試成功。 但是當我使用docker image時出現錯誤E /量角器-無法在頁面http：// localhost：4200 /上找到Angular：重試以尋找超出角度的角度 。

我的config.js

exports.config = {
  framework: 'jasmine',
  seleniumAddress: 'http://hub:4444/wd/hub',
  specs: ['e2e/myTest.js'],
  capabilities: {
    'browserName': 'chrome',
    'chromeOptions': {
      args: ['--no-sandbox']
    }
  },
  chromeOnly: true
};

myTest.js

describe('example test', function() {
  var homePage = require('./pages/homePage.js');
  var homePage = new homePage();

  it('my test...', function() {

    browser.get('http://localhost:4200/');
....

Package.json文件

{
  "name": "client",
  "version": "0.0.0",
  "license": "MIT",
  "scripts": {
    "ng": "ng",
    "start": "npm install && ng serve -H 0.0.0.0",
    "build": "ng build",
    "pretest": "webdriver-manager update",
    "test": "protractor config.js",
    "lint": "ng lint"
  },

docker-compose.yml的片段

  angular:...
  mypayara:...
  chrome:
    image: selenium/node-chrome:3.9.1-actinium
    volumes:
        - /dev/shm:/dev/shm
    depends_on:
        - hub
    environment:
        HUB_HOST: hub
  hub:
    image: selenium/hub:3.9.1-actinium
    ports:
      - "4444:4444"
    depends_on:
        - angular

當我使用命令開始測試時

docker-compose exec angular sh -c“ npm test”

我得到那個錯誤

[18:51:48] E/protractor - Could not find Angular on page http://localhost:4200/ : retries looking for angular exceeded
F[18:51:59] E/protractor - Could not find Angular on page http://localhost:4200/ : retries looking for angular exceeded

我在連接docker應用程序時遇到問題。 我正在嘗試此測試，結果是成功。

describe('angularjs homepage todo list', function() {
  it('should add a todo', function() {
    browser.get('https://angularjs.org');

    element(by.model('todoList.todoText')).sendKeys('write first protractor test');
    element(by.css('[value="add"]')).click();

    var todoList = element.all(by.repeater('todo in todoList.todos'));
    expect(todoList.count()).toEqual(3);
    expect(todoList.get(2).getText()).toEqual('write first protractor test');

    // You wrote your first test, cross it off the list
    todoList.get(2).element(by.css('input')).click();
    var completedAmount = element.all(by.css('.done-true'));
    expect(completedAmount.count()).toEqual(2);
  });
});

您知道我可以解決這個問題嗎？

Answer 1

只是要檢查原因是否為Angular，請將此行添加到代碼中的“ it”塊中。

await browser.waitForAngularEnabled(false);

看看發生了什么
