A tool to quickly test your protractor selectors from the command line


A tool to quickly test your Protractor selectors from the command line.

When I'm writing Protractor integration tests I spend most of my time finding the right selectors. I don't want to run the integration tests just to test a single selector.

The protractor tester allows you to open a Chrome browser and test your selectors from the command line.


Get the npm package:

npm install protractor-tester


sudo npm install protractor-tester -g

The protractor tester requires a Selenium server running at http://localhost:4444/wd/hub

If you need to install and run Selenium just follow these steps:

Get Protractor, it comes with some helper scripts to download and run the Selenium standalone server.

npm install protractor

Download the Selenium server and the chrome driver:


Run the Selenium server with the script that protractor just created:


How to run it

First, make sure you have a Selenium standalone server running on port 4444.

If you get the following error your are not running Selenium:

Unhandled error: Error: ECONNREFUSED connect ECONNREFUSED

The protractor tester will open a chrome browser. Now, from the command line you can test a selector, Go to a URL, or quit:

$ protractor-tester

  Test selector
❯ Go to url
[?] Enter the URL:
