PizzaScript is a JavaScript browser automation framework that records detailed webpage performance metrics.
It uses the Chrome DevTools Extensions API, so no external driver is required.
It includes:
- A script recorder / editor, with a REPL and debugger for interactively writing tests.
- A standalone script runner, for running a set of tests, capturing screenshots & performance metrics.
- A Java API, for embedding the script runner in your own projects.
- Inspect page load times and HTTP traffic.
- Wait on page load, HTTP traffic, elements to be visible
- Block/redirect certain URLs (e.g. block 3rd party beacon URLs)
- Modify request headers
- HTTP authentication support (Basic/Digest/NTLM)
- Emulate Mobile and Tablet devices
- Emulate network conditions (e.g. 3G/4G/Offline)
- Record WebSocket request/responses
- Take screenshots / Record video of page load
- Many useful CSS selector extensions (e.g. "a:contains(Click me!)" selects a link with the text "Click me!")
- Easy integration with Jenkins / CircleCI / Appveyor / Travis
First make sure the following are installed:
- Chrome 40+
- Java 8 JRE
Then download the latest PizzaScript release.
To open the script recorder:
bin/pizzascript-ide
To run a script and generate a report:
bin/pizzascript scripts/basic.js
To run a performance test as a continuous integration job see Jenkins Setup
The Chrome executable will be picked up from well-known Chrome install locations, if not found there then the PATH is searched. See Chrome Setup for troubleshooting and/or manually configuring the Chrome location.
Tested on Linux, OSX and Windows.
