6 best alternatives to Cypress as of 2019 - Slant

Nightwatch.js

Top Pro

You don't have to choose a testing framework

Nightwatch solves the Paradox of Choice among testing frameworks such as Jasmine, Cucumber or Mocha+Chai, by including its own BDD-style assertion library, based on Chai. See More

Top Con

No official BDD-style syntax support

Top Pro

Includes its own testing framework / assertions library

Top Con

Includes its own testing framework / assertions library

Unlike WebdriverIO, which lets you use various test frameworks and assertion libraries (e.g. Jasmine, Cucumber, Mocha + Chai), Nightwatch comes with its own BDD-style interface for performing assertions, based on Chai. Here's a simple test example: module.exports = { 'Demo test Google' : function (browser) { browser .url('http://www.google.com') .waitForElementVisible('body', 1000) .setValue('input[type=text]', 'nightwatch') .waitForElementVisible('button[name=btnG]', 1000) .click('button[name=btnG]') .pause(1000) .assert.containsText('#main', 'Night Watch') .end(); } }; See More

Top Pro

Test organization is out of the box

Supports page object model, custom commands, custom assertions, and globals.js. See More

Top Pro

3rd party integration with Cucumber

Though Cucumber is not officially supported, Nightwatch can be used with Cucumber. See More

CasperJS

Top Pro

Allows screenshots (either the full page or parts of it) if performing UI testing

There are times where you don't want to open up a browser for screencaps, that is where CasperJS comes to use, it can render the page using its own rendering engine and take and save a screenshot for you, all via the commandline See More

Top Con

Not for unit testing but rather UI testing

These are two extremely different concepts. CasperJS should be removed from this list See More

Top Pro

Easy to understand

Top Con

Cannot guarantee 100% accurate Webkit-based browser screenshots

QtWebKit is the rendering engine used by CasperJS. Keep in mind this is NOT the same rendering engine as Chrome; hence, if you want to be 100% sure of the results, you must run a Webkit browser (such as Chrome) yourself. See More

Top Pro

Written in JavaScript

Since all webdevs know JS, the start-up time of learning the framework will be reduced to zero, as your team can be productive from day one. See More

Top Pro

Easily integrates with other applications

Due to the simplicity of the framework, not only other libraries can be built with it, but it can be integrated with any web application as well. See More

Top Pro

Can run javascript code inside pages being tested

Can execute arbitrary javascript or load external JS into the page being tested. This feature is possible due to the presence of a rendering engine, and helps you see the effects of any client side scripting during your tests. See More

Geb

Top Pro

Easy integration with build systems

It's very easy to integrate Geb with any build system. See More

Top Con

Low IDE support

There are not many IDEs that support Geb. See More

Top Pro

Asynchronous requests testing is a easier

Asynchronous web pages can easily be tested with Geb as it has built in, easy to use support for testing such operations. See More

WebdriverIO

Top Pro

Works with any testing framework or assertion library

WebdriverIO lets you use your favorite testing framework (Jasmine, Mocha, Cucumber) and assertion library (Chai for Mocha). Other projects implement their own testing and assertion APIs, for example Nightwatch, Intern. It should be mentioned though that v4.2.16 has an incompatibility with at least tap v7.1.2: stdout/stderr written during a run gets lost. See More

Top Con

Must run with WDIO to debug

Tasks written in this beautiful Selenium API can only be debugged using the provided WDIO task runner. You can't set breakpoints within tasks, but you can have WDIO pause the run between Selenium commands. See More

Top Pro

Used by Chimp.js

Chimp.js, is an emerging web application test framework that implements easy sync tests using WebdriverIO, CucumberJS and Chai. Features include: synchronous style built-in "widget framework" (an implementation of the PageObject pattern) automatically downloads dependencies (ChromeDriver, PhantomJS etc.) works with SauceLabs and BrowserStack (CrossBrowserTesting TBD) automatically takes screenshots on failures works on Windows in addition to Linux and OS X automatically produces boilerplate code for step definitions, which you can copy, paste and edit file watcher reuses the browser sessions and can run only the tests you tag, to maximize development speed See More

Top Con

Selenium server must be started independently

selenium-webdriverjs starts the Selenium server automatically, and actually manages to achieve a faster startup time (4 seconds vs. 5.5) than WebdriverIO. See More

Top Pro

Excellent API documentation

Top Con

Have no docs for latest version (4.0.5)

Top Pro

Synchronous implementation of asynchronous browser commands

So you don't need to worry about promises See More

Top Pro

Config file generation wizard

Run wdio config and WebdriverIO will generate a config file for testing locally vs. in the cloud, specifying the test framework (Jasmine, Cucumber, Mocha), where to find tests and store screenshots etc. See More

Top Pro

Allows you to do visual regression tests using WebdriverCSS

WebdriverIO has a plugin called WebdriverCSS that allows you to do cross visual platfrom/browser tests with an integration to Applitools. See More

Top Pro

Provides plugins for gulp, grunt and other

WebdriverIO is accessible via gulp and grunt and even has a Sublime Text plugin for autocompletion. See More

Top Pro

Simpler syntax than selenium-webdriverjs and WD.js

selenium-webdriverjs: driver.get('http://www.google.com'); driver.findElement(webdriver.By.id('q')).sendKeys('webdriver'); driver.findElement(webdriver.By.id('btnG')).click(); WD.js: browser .get("http://www.google.com") .elementById('q') .sendKeys('webdriver') .elementById('btnG') .click() WebdriverIO: client .url('http://google.com') .setValue('#q','webdriver') .click('#btnG') See More

Top Pro

Used by Meteor's Velocity test runner

If you develop web applications with Meteor.js, you might want to use the xlovio:webdriver wrapper, because it's the Selenium binding behind the preferred testing framework (Chimp) promoted by the Velocity (Meteor's official testing framework) team for using BDD via Cucumber. See More

Top Pro

Selenium Server need not be started independently

Service is provided by WebdriverIO which over comes the con of starting selenium server independently. Reference: http://webdriver.io/guide/services/selenium-standalone.html See More

unobtainium

Top Pro

Extensible

Custom drivers for e.g. API testing or static HTML testing exist and are easily built. Driver modules allow you to extend the main driver (e.g. Selenium or Appium) with ease. See More

Top Pro

Platform agnostic because it is configuration driven

For test suites crossing multiple platforms, selecting the test target platform can be driven entirely by configuration. See More

Top Pro

Seamlessly automate mobile and desktop browsers

Based on either Appium or Selenium, the API remains largely the same when switching between different platforms. See More
