Simplicity is all about getting more done with less typing. Let's look at anexample: Can you read this? If you did, it might sound something like this: This is a relatively straightforward test, but consider how much code has beencovered by it, both on the client and the server!

Cypress is Like jQuery
If you've used jQuerybefore, you may be used to queryingfor elements like this: In Cypress, querying elements is the same: In fact, Cypressbundles jQueryand exposes many of its DOM traversal methods to you so you can work withcomplex HTML structures with ease using APIs you're already familiar with. Accessing the DOM elements returned from the query works differently, however: Let's look at why this is...
Cypress is Not Like jQuery
Question:What happens when jQuery can't find any matching DOM elements fromits selector? Answer: Oops!It returns an empty jQuery collection. We've got a realobject to work with, but it doesn't contain the element we wanted. So we startadding conditional checks and retrying our queries manually. Question:What happens when Cypress can't find any matching DOM elementsfrom its selector? Answer: No big deal!Cypress automatically retries the query until either:
Querying by Text Content
Another way to locate things -- a more human way -- is to look them up by theircontent, by what the user would see on the page. For this, there's the handycy.contains()command, for example: This is helpful when writing tests from the perspective of a user interactingwith your app. They only know that they want to click the button labeled"Submit". They have no idea that it has a type attribute of submit, or a CSSclass of my-submit-button.
It's very important to understand the mechanism Cypress uses to chain commandstogether. It manages a Promise chain on your behalf, with each command yieldinga 'subject' to the next command, until the chain ends or an error isencountered. The developer should not need to use Promises directly, butunderstanding how they work is helpful!
As we mentioned previously in this guide: What makes Cypress unique from other testing tools is that commandsautomatically retrytheir assertions. In fact, they will look "downstream"at what you're expressing and modify their behavior to make your assertionspass. You should think of assertions as guards. Use your guards to describe what your applica...
Almost all commands can time out in some way. All assertions, whether they're the default ones or whether they've been addedby you all share the same timeout values.
