自動エンドツーエンドテスト-Protrator Tutorial
14367 ワード
Basic
Protractor is an end-to-end test framework for AngularJS applications. Protractor runs tests against your application running in a real browser, interacting with it as a user would.
Test Like a User
Protractor is built on top of WebDriverJS, which uses native events and browser-specific drivers to interact with your application as a user would.
For AngularJS Apps
Protractor supports Angular-specific locator strategies, which allows you to test Angular-specific elements without any setup effort on your part.
Automatic Waiting
You no longer need to add waits and sleeps to your test. Protractor can automatically execute the next step in your test the moment the webpage finishes pending tasks, so you don’t have to worry about waiting for your test and webpage to sync.
Setup
Use npm to install Protractor globally with: npm install -g protractor
This will install two command line tools, protractor and webdriver-manager . Try running protractor --version to make sure it's working.
The webdriver-manager is a helper tool to easily get an instance of a Selenium Server running. Use it to download the necessary binaries with: webdriver-manager update
Now start up a server with: webdriver-manager start
This will start up a Selenium Server and will output a bunch of info logs. Your Protractor test will send requests to this server to control a local browser. You can see information about the status of the server at http://localhost:4444/wd/hub.
Write a test
Open a new command line or terminal window and create a clean folder for testing.
Protractor needs two files to run, a spec file and a configuration file.
Let's start with a simple test that navigates to the todo list example in the AngularJS website and adds a new todo item to the list.
Copy the following into todo-spec.js : 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);
});});
The describe and it syntax is from the Jasmine framework. browser is a global created by Protractor, which is used for browser-level commands such as navigation with browser.get .
Configuration
Now create the configuration file. Copy the following into conf.js : exports.config = {
seleniumAddress: 'http://localhost:4444/wd/hub',
specs: ['todo-spec.js']};
This configuration tells Protractor where your test files ( specs ) are, and where to talk to your Selenium Server ( seleniumAddress ). It will use the defaults for all other configuration. Chrome is the default browser.
Run the test
Now run the test with: protractor conf.js
You should see a Chrome browser window open up and navigate to the todo list in the AngularJS page, then close itself (this should be very fast!). The test output should be 1 test, 3 assertions, 0 failures . Congratulations, you've run your first Protractor test!

This is a simple tutorial that shows you how to set up Protractor and start running tests.

Prerequisites
Protractor is a Node.js program. To run, you will need to have Node.js installed. You will download Protractor package using npm, which comes with Node.js. Check the version of Node.js you have by running node --version . It should be greater than v0.10.0.
By default, Protractor uses the Jasmine test framework for its testing interface. This tutorial assumes some familiarity with Jasmine, and we will use version 2.3.
This tutorial will set up a test using a local standalone Selenium Server to control browsers. You will need to have the Java Development Kit (JDK)installed to run the standalone Selenium Server. Check this by running java -version from the command line.
