Ranked in these QuestionsQuestion Ranking
Pros
Pro Codeless automated testing
Endtest allows you to create automated tests for web applications, directly on their cloud infrastructure. No coding skills are required.
You can also choose the action "Execute Javascript" for a more flexible test run.
Pro Running your automated tests on their cloud infrastructure
You can easily run your automated tests on their platform, just by clicking the run button.
Pro Designed for Continuous Integration
It has an API which allows testers to run it on Jenkins or Team City. Other than that, it has a built-in test scheduler to allow testers to preset test executions.
Pro Now supports mobile testing
Endtest has added a new feature which now supports mobile testing for both Android and iOS (.apk and .ipa).
Pro Option to export your automated tests in different formats, including .EXE
You can export your automated tests in a variety of different formats, and run them on your own infrastructure. The formats are either in Python file format or executable file format (.EXE).
Pro Now supports a wider variety of browsers, operating system and devices
As of March 2018, Endtest can now support multiple platforms (Windows, MAC, Android and iOS), Operating Systems, and more than a handful of devices for both Android and iOS.
Pro Super fast and affordable.
Pro Premium version is relatively cheaper than most in the market
Their pricing plan ($79/month or $650/year) includes team plan upgrade, which means the whole team, regardless of the number of users, will only need to subscribe to the $79/month or $650/year plan. This includes unlimited test runs, test exports, recordings, etc.
Pro It's mostly free to use
The free plan covers a lot, you can have up to 3 test suites, and you can run your automated tests as many times as you want. The pro plan includes some very advanced options that you might need only if you're working with a team (for example, the collaboration feature, schedule test run, API for Jenkins, etc.).
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
Pro Easy to understand
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.
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.
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.
Cons
Con Doesn't support a wide array of browsers and/or operating systems
Because it's still in its infancy, it doesn't yet have a huge variety of browsers and operating systems.
Con Free plan has limited time storage for test suites
If you are using the free plan, keep in mind that the test suites created there are scheduled to be deleted after around 2 weeks. Endtest will send you a notification email the day before mentioning "Test suites from users who are not on the PRO Plan get automatically deleted after some time," and offering for you to upgrade to PRO.
Con Codeless and locks you in rendering your efforts useless if you want to switch
Con Bad UI
Con Not for unit testing but rather UI testing
These are two extremely different concepts. CasperJS should be removed from this list
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.
