Run tests in your local environment
The Tunnel makes it easy to run Selenium tests in your private staging environment.
You might want to test a new feature or a big refactor of your local code, to make sure all regression tests still pass.
With our Tunnel this is very easy to do. All you need to do is point your tests to http://localhost and port 4445 instead of using our grid http://hub.testingbot.com port 4444.
The Tunnel is a Java based program (jar) which contains our very own secure HTTP(s) proxy, which will relay requests to our grid.
This way a browser on one of our instances can easily fetch webpages through the tunnel.
Optimized for Speed
Setting up a Tunnel means we boot a pristine VM server just for you. This takes about a minute to launch.
We added an accelerator on our end of the tunnel called Squid, which will cache static content flowing through the tunnel.
This optimisation will make the tunnel fast because cached static content no longer needs to go through the tunnel.
The Tunnel uses zlib ssh compression to minimize the traffic going through the tunnel.
You can run multiple tunnels with 1 account. This means you can dedicate xx machines on your LAN to run xx tunnels.
With multiple tunnels, you do not have to worry about load issues when running xx tests in parallel.
Every request to and from our servers will pass through the Tunnel, which is based on the SSH protocol.
A fresh VM is booted up just for you and when your tests are finished the tunnel and VM server will be destroyed.
We've built a strong Tunnel which can handle a lot of traffic, even during parallel testing.
The Tunnel is built in Java with proven code and runs on a standard JVM.
Both HTTP and HTTPS usage is supported inside the tunnel.
Starting the tunnel happens with a simple command on the commandline and offers options like verbose logging and fast-fail regexes.
Works on Mac, Linux, BSD and Windows.
Setting up and using the Tunnel is easy.
Download the JAR file from our website and run it on your commandline.
All you need to do is replace the API_KEY and API_SECRET with your own key and secret.
You will see "You may start your tests" when your Tunnel is ready.
The Tunnel will create a ~/.testingbot file on your local system where it saves the API_KEY and API_SECRET.
This way, you can save the necessary credentials in the file and then just start the tunnel without passing credentials to the tunnel.
To prevent certain websites or pages from being proxied by our tunnel, please use the fast-fail regex:
If you are behind an HTTP proxy, please start the tunnel with these extra arguments:
The system requirements depend on how you are going to use the tunnel.
If you intend to do parallel testing, you will need to increase the CPU and RAM of the machine running the tunnel.
By default, a machine with 4GB ram and 3GHz processor should be enough.
Shutting down tunnel
It is recommended to do a graceful exit of the tunnel every time, otherwise the tunnel will remain active in our system since we never received a shutdown command.
To do a graceful exit, please use CTRL+C in the process window or remove the TestingBot pid file: testingbot-tunnel.pid. This will trigger a graceful exit, send the shutdown command to TestingBot and clean up everything.
