**Mocha** is a feature-rich JavaScript test framework that runs on **Node.js** and in the browser; it simplifies the process of asynchronous testing. Mocha tests run serially to allow for flexible and accurate reporting *while* mapping uncaught exceptions to the correct test cases.

# Installation
Mocha can be installed with npm globally:

```xml
npm install --global mocha
```
It can also be installed as a development dependency for your project:
```xml
npm install --save-dev mocha
```

> Note that as of v6.0.0, Mocha requires Node.js v6.0.0 ​or newer.



How to install Mocha
