# Overview

We know, as a developer, testing is not always the most exciting part of building a project, but we hope at the end of this section we can change your mind. We'll show you how testing is now cool and the different ways we can approach it.

## Installation

For this section we're going to use [Jest](https://jestjs.io/) for unit testing and [Cypress](https://www.cypress.io/) for end-to-end testing. Again, one way to install them is by using the UI, the other way is by running in the command line `vue add @vue/cli-plugin-unit-jest` and `vue add @vue/cli-plugin-e2e-cypress`

After installing this 2 plugins you'll notice a bunch of changes to your project. A new test folder was created in the root directory with a bunch of yet to learn files. Also 2 new scripts were added to **package.json** and you could even give it a try by running `npm run test:e2e` and `npm run test:unit`

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://devworkshops.gitbook.io/masteringvuejs/testing/overview.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
