Key concepts to be familiar with for successful Cypress.io testing

What insight I've gained from my experience using Cypress is that there are two fundamental areas that one must grasp for Cypress.io journey.

• Underlying mechanics of Cypress.io
• Directions on utilizing Cypress.io

Let me tackle the underlying mechanics part first:-

• Asynchronous programming: Cypress tests are executed asynchronously, which means that commands are not executed in a linear, synchronous order. This allows Cypress to run multiple commands at the same time, making tests faster and more efficient.
• Promises: Cypress commands return Promises, which are used to handle the results of asynchronous operations. Promises can be used to specify what should happen once a command has completed, such as asserting that a specific element is visible on the page.
• Chaining: Cypress commands can be chained together to perform multiple actions on a single element. This allows for more readable and maintainable code.
• Event handling: Cypress tests can also interact with events on the web page, such as clicks, form submissions, and key presses. This allows you to simulate user interactions and test how your application responds to different events.
• DOM manipulation: Cypress uses JavaScript to interact with the Document Object Model (DOM) of the web page under test. This includes interacting with elements, such as clicking buttons or filling out forms.

Assuming you are intrigued in utilizing Cypress for your advantage, continuing to read this then:-

• Functional programming: Cypress tests are written in a functional programming style, which means that they are composed of small, reusable functions that can be combined to create more complex tests.
• Commands: Understanding of the built-in Cypress commands and how to use them to interact with the application.
• Hooks: Understanding of the various hooks available in Cypress, such as "beforeEach", "afterEach", "before", and "after".
• Assertions: Cypress tests include assertions, which are used to check that the application behaves as expected. Cypress provides a built-in assertion library, called Chai, which can be used to make assertions about elements on the page, as well as the state.
• Network Traffic: Knowledge of how to control and manipulate network traffic for testing purposes.
• Debugging: Understanding of the various debugging tools available in Cypress, such as time-travel debugging and network traffic inspection.
• Test Reporting: Understanding of the test reporting features in Cypress and how to use them to analyze test results.
• Test Organization: Knowledge of how to structure and organize tests for maintainability.
• Selectors: Cypress uses selectors, such as CSS selectors, to locate elements on a web page. Selectors are used to interact with elements in the DOM, such as clicking on a button or checking the text of an element.Common selectors include id, class, and tag. Cypress also supports advanced selectors such as data-* attributes, child selectors, and more.
• JavaScript events: Cypress also allows to trigger DOM events such as submit, change, blur, key down and more, via .trigger() command to test the application behavior.
• jQuery: Cypress leverages jQuery by allowing you to use its selector and manipulation capabilities within your tests. With jQuery, you can select elements on the page, manipulate their state, and make assertions about their behavior.
