Protractor Selenium
Protractor is an end-to-end testing framework specifically designed for automating web applications built with Angular and AngularJS. While Protractor uses the Selenium WebDriver under the hood for browser automation, it provides additional features and capabilities tailored to testing Angular applications. Here’s an overview of Protractor and how it works with Selenium:
Key Features of Protractor:
Angular-Specific Locators: Protractor introduces Angular-specific locators like
by.model,by.binding, andby.repeaterto make it easier to interact with Angular-specific elements and data bindings.Automatic Waiting: Protractor has built-in support for Angular’s automatic waiting mechanisms. It waits for Angular to stabilize before interacting with elements, ensuring that your tests are synchronized with Angular’s asynchronous operations.
AngularJS and Angular Support: Protractor supports both AngularJS (1.x) and Angular (2+), making it suitable for testing applications built with either framework.
Page Object Model: Protractor encourages the use of the Page Object Model design pattern for organizing your test code into reusable and maintainable components.
Angular-Specific Commands: Protractor provides commands like
browser.waitForAngular(),browser.waitForAngularEnabled(), andbrowser.addMockModule()to interact with Angular-specific behavior.Parallel Testing: You can run tests in parallel using Protractor, which can significantly reduce test execution time.
Cross-Browser Testing: Protractor can be used with various web browsers like Chrome, Firefox, and Edge, just like Selenium WebDriver.
How Protractor Works with Selenium:
Installation: To get started with Protractor, you need to install both Protractor and WebDriver Manager (for managing browser drivers) using npm (Node Package Manager).
Configuration: Create a configuration file (typically
protractor.conf.js) to specify settings like the base URL of your application, the browser to use, and test-specific configurations. You can also define the location of your test scripts and set up capabilities for different browsers.Writing Test Scripts: Write your test scripts in JavaScript using Protractor’s API. Protractor provides a set of functions for interacting with elements, navigating between pages, and performing various actions on your Angular application.
Running Tests: Use the
protractorcommand-line tool to execute your Protractor tests. Protractor will start a Selenium WebDriver instance, launch the specified browser, and run your test scripts.Test Reporting: Protractor generates test reports, which can include information about passed and failed tests, error messages, and screenshots.
Example Protractor Test Script:
Here’s a simple example of a Protractor test script that navigates to a web page and interacts with an Angular element:
describe('Protractor Demo App', function() {
it('should add two numbers', function() {
browser.get('https://example.com');
element(by.model('first')).sendKeys(1);
element(by.model('second')).sendKeys(2);
element(by.id('gobutton')).click();
expect(element(by.binding('latest')).getText()).toEqual('3');
});
