This course will provide you with important information, principles, and experience-based advice, to enter the world of testing methodologies. 

Here, you will learn the best practices to follow to write useful and lasting tests, how to test different user flows without a working back-end, how to write effective end-to-end tests (E2E), and how to integrate tests into development and Continuous Integration pipelines.

At the end of the course, you will be able to apply the fundamental principles of the test methodologies to understand what and how to test effectively.

Front-end Testing 101: Integration and End-to-end Testing

## VS code Intellisense 
How do we leverage VS Code Intellisense to document our custom command?

## How to leverage

We need to use a TypeScript definition file, to add them you need to:

- Create an `index.d.ts` file in the `cypress/support/signup` directory (where the `signup-v1.js` file is).

- Add the data itself. 

We will not go into detail about  TypeScript itself, although we will take a look at the results from the file.  

File: `cypress/support/signup/index.d.ts`
