# testcafe-hammerhead
|
|
`testcafe-hammerhead` is a powerful Web proxy used as a core for the [TestCafe](https://github.com/devexpress/testcafe) testing framework.
|
|
|
|
## Core Concepts
|
|
|
|
`testcafe-hammerhead` is a URL-rewriting proxy. This means that it rewrites all properties of the appropriate JavaScript objects that contain a URL value (`Location`, `HTMLLinkElement.href`, etc). You can see it if you open a proxied page, invoke the browser's DevTools and inspect any element.
|
|
|
|
In addition, the proxied web page does not know that it is opened under a proxy. The proxy intercepts access attempts to all URL-containing properties and provides the original values.
|
|
|
|
## First Look
|
|
1. Clone the Hammerhead repository
|
|
```cmd
|
|
git clone https://github.com/DevExpress/testcafe-hammerhead.git
|
|
```
|
|
1. Go to the `testcafe-hammerhead` folder
|
|
```cmd
|
|
cd testcafe-hammerhead
|
|
```
|
|
1. Install the dependencies
|
|
```cmd
|
|
npm install
|
|
```
|
|
1. Run the [Hammerhead playground](https://github.com/DevExpress/testcafe-hammerhead/blob/master/test/playground/server.js) to see our proxy in action
|
|
```cmd
|
|
node node_modules/gulp/bin/gulp http-playground
|
|
```
|
|
|
|
This opens a playground page where you can specify a webpage to proxy. Enter the page URL and hit **Proxy!**.
