Cypress Testing Interview Questions| Postman Interview Questions For Experienced
What is Cypress?Cypress is a test automation tool that is used for creating Automated Tests in our application. Cypress helps by working in the same area where tools such as Selenium works, it uses real browsers by allowing the developers to create a higher quality of tests. It also can take screenshots and videos by using Testing Process which makes it easier to debug errors within the tests.
What is Cypress CLI?Cypress CLI helps in providing the ability for running our cypress tests in Command-Line. It is a feature that is used to run our cypress tests in Pipelines. It also provides Options and Flags Control of the cypress Test Behavior.

cy.visit(): cy.visit() is used to navigate to the specific website Ex: cy.visit(‘http://www.google.com’);cy.log(): cy.log is used for display cypress console logs during execution Ex: cy.log(‘test 123’);cy.get(): cy.get is used for getting dom element in cypress, once we get dom element we can perform action on that like click, type etc. Example: let myElement = cy.get(‘#username’)cy.url(): cy.url() is used to Get the current URL of the page that is currently active.Example: Consider you have navigate to https://google.com using cy.visit();, now you can use the cy.url() to get the url back.
Note: First time when we execute npm cypress open command, cypress prepares the framework ready for you. This involves creating folder structure such as cypress, support, plugin, integration etc. This happens only when we execute npm cypress open command for the first time, subsequent execution of this command only launches the cypress window since set up is done already.

Joe [00:04:38] Next questions from Nathaniel. He wants to know Because Cyprus is interacting with the web app directly. Is there a layer of code, example risk above that, that Selenium would test, but Cypress is skipping? For example, would there be a difference between telling the app that I clicked versus emulating a real user clicking through the browser?
Joe [00:13:35] Its great that this allows developers adding test to their code. But as a QA automation engineer, the only access we have is to the pages and not the application source code. Do you agree that end-to-end tests with pages and Page objects still has a place even with this tp technique?
Joe [00:09:23] Next question is from Christina. Christina wants to know, “By using app actions, you are not touching the UI. How are we sure that the functional elements work for example, they can actually click on an element or type in a field. Isnt this proven to error?” I think you touched on this a little bit already.
Gleb [00:18:09] Its native to JavaScript. It can only be Javascript because its running in the browser and the browser only supports javascript. If you want to call that code directly, your code has to be javascript as well. Now WebDriver has you know evaluate javascript where you can kind of simulate, you can kind of send the command that will load your javascript, but its not going to be the same. Its always going to be serialized HTTP POST request going through your browser, and then the browser is evaluating them but who knows if the object is ready actually to receive that. When you run your test and browser in Cyprus. Your javascript is executing in the same loop in the same event engine as the application so. So everything is so much easier from JavaScript.
Gleb [00:05:00] Yes. So right now, Cyprus is a completely JavaScript solution. That means a synthetic event. Its creating an event object in JavaScript and sending it or dispatching it to a button, for example which might not necessarily work the same way as native events, We are adding native events. So the next thing for Cypress on our road map is actually supporting Native events. And this will enable you to do things like file upload or download or copy paste into your clipboard. You will still have the synthetic events, but you also will have native events for all events. So this will remove like tiny gaps like that. At the same time, we go back to what I do from with app action. The point of app action is not to stop testing the UI and stop clicking, its also when your testing a feature X you go through a page, and you click on a particular button when you are testing X. But when you are testing feature Y, you dont go for a feature X again from a page. Instead, you go directly set up your space for your test then test feature Y. To avoid this duplication but flow part of interacting with the page. So you still cover all the features of the page at least once you dont repeat yourself unnecessarily.
