jasminewd2

What is jasminewd2?

The jasminewd2 package is a bridge between Jasmine and WebDriverJS, allowing for seamless integration of asynchronous WebDriverJS commands in Jasmine tests. It provides utilities to handle promises and asynchronous operations in a more readable and manageable way.

What are jasminewd2's main functionalities?

Asynchronous Testing

This feature allows you to write tests that wait for promises to resolve before making assertions. The code sample demonstrates how to navigate to a URL and then check the page title, ensuring that the test waits for the navigation to complete.

describe('Asynchronous specs', function() {
  it('should wait for the promise to resolve', function() {
    return browser.get('http://www.example.com').then(function() {
      expect(browser.getTitle()).toEqual('Example Domain');
    });
  });
});

Custom Matchers

This feature allows you to define custom matchers to extend Jasmine's built-in matchers. The code sample shows how to create a custom matcher `toBeWithinRange` that checks if a number falls within a specified range.

describe('Custom matchers', function() {
  beforeEach(function() {
    jasmine.addMatchers({
      toBeWithinRange: function() {
        return {
          compare: function(actual, expected) {
            var result = {};
            result.pass = actual >= expected[0] && actual <= expected[1];
            if (result.pass) {
              result.message = 'Expected ' + actual + ' to be within range ' + expected;
            } else {
              result.message = 'Expected ' + actual + ' to be within range ' + expected + ' but it was not';
            }
            return result;
          }
        };
      }
    });
  });

  it('is within range', function() {
    expect(100).toBeWithinRange([90, 110]);
  });
});

Handling Asynchronous Setup and Teardown

This feature allows you to perform asynchronous operations in setup and teardown functions. The code sample demonstrates how to navigate to a URL before all tests and quit the browser after all tests, ensuring that these operations complete before proceeding.

describe('Asynchronous setup and teardown', function() {
  beforeAll(function(done) {
    browser.get('http://www.example.com').then(function() {
      done();
    });
  });

  afterAll(function(done) {
    browser.quit().then(function() {
      done();
    });
  });

  it('should have a title', function() {
    expect(browser.getTitle()).toEqual('Example Domain');
  });
});

Other packages similar to jasminewd2

protractor

Protractor is an end-to-end test framework for Angular and AngularJS applications. It is built on top of WebDriverJS and integrates seamlessly with Jasmine, providing additional features like automatic waiting and Angular-specific locators. Compared to jasminewd2, Protractor offers a more comprehensive solution for testing Angular applications.

webdriverio

WebdriverIO is a popular WebDriver binding for Node.js. It supports various test frameworks, including Jasmine, Mocha, and Cucumber. WebdriverIO provides a rich set of features for writing and managing end-to-end tests, including support for asynchronous operations and custom commands. Compared to jasminewd2, WebdriverIO offers more flexibility in terms of test framework integration and additional utilities.

nightwatch

Nightwatch.js is an end-to-end testing framework built on top of Selenium WebDriver. It provides a simple syntax for writing tests and includes built-in support for running tests in parallel. Nightwatch.js also supports various test frameworks, including Mocha and Cucumber. Compared to jasminewd2, Nightwatch.js offers a more integrated solution with built-in test runner and assertion library.

README

jasminewd

Adapter for Jasmine-to-WebDriverJS. Used by Protractor.

Important: There are two active branches of jasminewd.

• master is an adapter for Jasmine 1.3, and uses the package minijasminenode. It is published to npm as jasminewd.
• jasminewd2 is an adapter for Jasmine 2.x, and uses the package jasmine. It is published to npm as jasminewd2.

Features

• Automatically makes tests asynchronously wait until the WebDriverJS control flow is empty.

• If a done function is passed to the test, waits for both the control flow and until done is called.

• Enhances expect so that it automatically unwraps promises before performing the assertion.

Installation

npm install jasminewd2

Usage

Assumes selenium-webdriver as a peer dependency.

// In your setup.
var JasmineRunner = require('jasmine');
var jrunner = new JasmineRunner();
require('jasminewd2');

global.driver = new webdriver.Builder().
    usingServer('http://localhost:4444/wd/hub').
    withCapabilities({browserName: 'chrome'}).
    build();

jrunner.projectBaseDir = '';
jrunner.execute(['**/*_spec.js']);

// In your tests

describe('tests with webdriver', function() {
  it('will wait until webdriver is done', function() {
    // This will be an asynchronous test. It will finish once webdriver has
    // loaded the page, found the element, and gotten its text.
    driver.get('http://www.example.com');

    var myElement = driver.findElement(webdriver.By.id('hello'));

    // Here, expect understands that myElement.getText() is a promise,
    // and resolves it before asserting.
    expect(myElement.getText()).toEqual('hello world');
  });
})
