In the company I will be building test automation framework and my new company develops apps mainly using AngularJS/TypeScript. I was planning to build Protractor-Jasmine framework but a friend of mine told me about Cypress and heard that its users are very satisfied with it. I am trying to understand the capabilities of Cypress and as the final goal to differentiate these two tools. Can anyone advice me on this in a nutshell pls...
I've used both Protractor and Cypress extensively. Cypress is the easier and more reliable tool, whereas Protractor is the more powerful tool. Your choice of tool should depend on your specific testing needs. Here are some advantages and disadvantages of each tool:
More reliable (tends to throw fewer intermittent false failures)
Easier to read code (handles promises gracefully)
Cannot switch between browser tabs
Cannot switch to iFrames
Cannot specify clicks or keypresses explicitly as if a real user was interacting
Cannot move the mouse to specific co-ordinates
Sometimes has trouble switching between different top-level domains, so not good for testing external links
Cypress is a newer tool with less extensive documentation and less community support
More powerful because it is Selenium-based - it can switch between tabs, it can handle external links to other domains, it can handle iFrames, simulate keypresses and clicks, and move the mouse to specific co-ordinates within the browser.
More extensive community support and documentation
Slower and more brittle - in general there is a higher likelihood of cryptic and/or intermittent errors which may cause your tests to fail even though there is nothing wrong with your application
For highly experienced automation engineers, the fundamental "brittle" nature of Selenium can be worked around - it can be reliable but only if you really know what you are doing
Less graceful handling of promises - relies on async/await or .then to manage the order of execution. Therefore it is a bit harder to read the code.
Harder to set up, and the method of setup impacts its reliability. For example, a hub/node configuration where the selenium jar is on a different physical machine than the browser under test will cause unreliability in your tests. Not everyone knows about this type of thing, so it's common to find Selenium frameworks that are set up poorly.
It's probably better to use Cypress if
you're at a smaller company and have a close relationship with developers who can help write hooks or stubs in their code to assist your testing
you don't need to do things like switch between tabs or test links to external top-level domains
It's probably better to use Protractor if
You might need to switch between tabs or test external links to other domains within the scope of your framework
You want to use a more accurate simulation of how a real user interacts with a browser (i.e. click at this location, type these keys)
You're at a company where you won't have any support from developers in writing hooks or stubs to make their code more testable in a less powerful framework like Cypress

Fast running, execute story groups in parallel by multi-workers
Built-in single page report render
Cover page view, REST API and cookies test
I am using Node 12 for server scripting and have a function to generate PDF and send it to a browser. Currently, we are using PhantomJS to generate a PDF. Some web post shows that we can achieve PDF generation using Puppeteer. I was a bit confused. Should we move to puppeteerJS? Which one is better with NodeJS for generating PDF?
You better go with puppeteer. It is basically chrome automation tool, written in nodejs. So what you get is PDF, generated by chrome itself. I guess there is hardly better PDF generation tool for the web. Phantomjs is already more or less outdated as technology. It uses some old webkit port that's quite behind in terms of standards and features. It can be replaced with puppeteer for every single task.
I suggest puppeteer to go for. It is simple and easy to set up. Only limitaiton is it can be used only for chrome browser and currently they are looking into expanding into FF. The next thing is Playwright which is just a scale up of Puppeteer. It supports cross browsers.
My company was looking for a testing tool that would integrate easily with AWS Amplify and quickly provide value. I created a POC for each tool we were exploring and showed it to the team (since we all want to contribute to the testing framework). Cypress was by far the easiest to go from nothing to running tests that were finding bugs in our web application.
The only difficulties I had with Cypress were working with iframes and the fact it does not currently handle new tabs. Cypress currently supports Chrome, Edge, Electron (headless) and has Firefox in beta so if IE is something you need to support, you might want to use another tool in conjunction or in place of Cypress.
Cypress is very well documented with a very responsive support team. Recently the Cypress team released the 'Real World App' as a showcase for implementing good tests with best practices.
As we all know testing is an important part of any application. To assist with our testing we are going to use both Cypress and Jest. We feel these tools complement each other and will help us get good coverage of our code. We will use Cypress for our end to end testing as we've found it quite user friendly. Jest will be used for our unit tests because we've seen how many larger companies use it with great success.
