What is cypress automation?
Hi, many of you here as Dev/QA who work on Web Development and would have written web UI Test Automation for your projects with the Selenium Framework, right?
Here are some of the problems we have experienced when we do that:
The test takes a very long test execution time even if we do the parallel test.
Keep up with browser selenium Web Driver updates to keep up with the version of Browser upgrade, which browser softens.
That doesn’t mean selenium isn’t good, but with web technology developing far beyond the new Frontend Framework, the way code writers are changing. There are a lot of new browser effects, making the cypress Automation Framework adapt as well. For this, you should also know the framework meaning.
Go back and see selenium WebDriver
Selenium has been born since 2004 in an era when most websites are also where in Web 1.0.
Where Web1.0 is a Web at Provide Static Content for Users to read, not much interaction with Users. Selenium works well and is perfect for testing during that period.
Over time, web development has been developed to the point where it is called Web 2.0 which is supposed to be more dynamic/User Generated Content, as well as social network acquisitions such as Facebook, Twitter, making Web Technology change forever, making testing more difficult. And having to write more complex code to support the web content that can change, many of which are likely to be difficult to find problems with the content of the web that can change, which many people are likely to have experienced problems with writing.
And more importantly, Selenium’s architecture may have contributed to the inefficient Test writing.
If we look at the Architecture Framework, one scenario user action, such as clicking the button behind that operation, the client (Selenium-Bindings language), there will be a JSON Wire Protocol to WebDriver.
And then, WebDriver will order click on the browser to see a lot of overhead scans on one run (and as a remote command order), which slows down the results of the test when the Test is available.
Cypress is a Test Framework designed in 2014 (10 years after Selenium started) to solve problems mentioned earlier.
With Cypress being run-up in the same Run Loop Process as our Web Application,
This is behind the scenes of the nodeJS server that manages test code and application operations to work seamlessly, as well as manage the work they want to use, but the scope is outside of the browser.
Cypress’s distinctive features
Test at every level: From Unit/Integration to End to End Test (according to concept test pyramid) and can test both UI and API Test.
Native Access: We can access Objects, Window, DOM Elements, Local Storage, Web Application Functions from all our Test Code. This one’s very personal, I’ve been looking for a long time.
Support making Mock/Spies/Stub: Can create mock objects in the App, such as Network Requests, Local Storage, 3rd Party Applications. Cypress itself provides all these things without relying on other tools, which will allow us to control and write Test Behavior more accurately.
Debugging is easy: Cypress Perform snapshots of every step running the test for us to automate Screenshot, Video Recorded while running Test.
Automatic Wait: We don’t have to write code for Wait or Sleep anymore.
Realtime Reloads: Cypress will have our Monitor Test Code at any time when our Test Code changes, cypress will automatically reload the Test (this one is cool).
Cypress is an Open Source Project, it is free to use (MIT License) except for some features such as Dashboard and Parallel Test, which requires additional purchase.
Cypress and its compatibility with browsers!
Now, Cypress Support runs only on chrome browser. But there are plans to add other Support Browser, such as IE, and cloud at SourceLab.
Overall, we think the cypress framework fits in writing tests for Web Applications in this Web 2.0 era.
