SELENIUM BOX - Frequently asked questions


Is Selenium Box a cloud service like Saucelabs or Browserstack?

No, Selenium Box is an on premise Selenium Grid solution making it extremely secure and scalable. No external access to the application under test is required.


What is the difference between a cloud service and Selenium Box?

The fundamental difference between a cloud service and SBOX is the fact that SBOX runs completely inhouse. This results in superior performance over cloud solutions and allows for much tighter integration into your surrounding systems such as CI, reporting. 

Additional aspects are better and easier debugging capabilities, reporting and monitoring, stability, custom requirements i.e. self-signed SSL certificates, unlimited scaling option. 


Can I do a proof of concept in my environment?

Yes. This is our recommended approach. Especially larger companies have specific requirements in terms of infrastructure, network etc. We strongly recommend a proof of concept. 


Is the proof of concept free of charge? 

No. We usually charge a flat fee for a proof of concept to cover our expenses i.e. for travel. If the client decides to buy a Selenium Box license after a successful proof of concept we reimburse the fees. 


What do I need to run the Selenium Box in my environment?

Selenium Box runs on any Linux system with Docker installed. It can run on bare metal as well as in a virtual machine. We can provide benchmarking scripts for your infrastructure in order to ensure that you can get the maximum performance out of the Selenium Box.


Can I run Selenium Box in my own cloud? 

Yes. Selenium Box is fully cloud compatible. Nested Virtualization needs to be available. 


How does the license model work?

Selenium Box is based on an annual subscription. 


Do you provide AN evaluation license?

Yes. Clients can request an evaluation license if they want to try out Selenium Box. 


Is there a limit on running tests in parallel?

No. You can run as many tests in parallel as your hardware resources are capable of. If you want to run more tests, you simply need to add more CPU / RAM.


Is there a limitation on testing minutes that I can use?

No. The testing minutes are unlimited due to the on premise nature of Selenium Box.


is there any logging / monitoring capability built into Selenium Box?

Yes. Selenium Box has an advanced logging and monitoring mechanism which can easily be customized and integrated into the customer environment. Selenium Box logs pretty much everything. Those logs can be accessed and then aggregated and visualized based on your needs. 


Can I run the Selenium Box in my company infrastructure?

Yes. Selenium Box can be installed in any Linux system that supports Docker.


Does Selenium Box automatically update when A new browser is released? 

Yes. There is an auto-update option which automatically downloads and installs new browser, driver or Selenium versions after they are tested and released by Element34. This makes the Selenium Box completely maintenance free.


How does the update process work?

After new browsers, Selenium or driver versions are released we thoroughly test them and release them. Selenium Box immediately (if auto-update is enabled) picks up the newly released versions and installs them. From a user perspective this process is completely transparent and seamless.


Does the Selenium Box support HTTPS? 

Yes, you can of course use https with the Selenium Box. 


Can I install my own Windows image in the Selenium Box in order to run my company Windows image and browser?

Yes. Corporate Windows images can be installed into the Selenium Box system.


How much effort is it to operate the Selenium Box?

Selenium Box is a fully self contained system. There is no effort required to manage the Selenium Box when running in auto-update mode. The host where the Selenium Box is running on is usually provisioned by the corporate operations team.


Do I need to do anything when a new browser or Selenium version releases?

No. Selenium Box can automatically update itself when we release a new binary. Customers however have the option to manually upgrade if that's what they want. Selenium Box issues an alert that there is a new version available. The upgrade is done by simply selecting the new version the the maintenance console of the Selenium Box.


How long does it take to have the latest browser and Selenium Versions available on the Selenium Box after they are released by the browser manufacturers?

We monitor the release of new browsers 24/7. Each time a new browser, Selenium or driver version is released we automatically build the corresponding images, run them through thorough tests and if everything works well we release them to the Selenium Box. All of this procedure is automated. Most of the time the new images are released to the Selenium Box within 24-48 hours of the initial release.


Do I need to check the compatibility of the new browsers / Selenium releases?

No, we do this for you. When we release new images to the Selenium Box, our customers can be sure that the versions are compatible with each other.


Do I need to write my tests in a special way to execute them on the Selenium Box?

No. Selenium Box uses the standard Selenium protocol and Desired Capabilities. 


Do tests share browser resources? 

No. Each test is run in an isolated environment and does not share any resources with other tests. A new browser is started for each test. After the test finishes, the browser is closed and the environment is destroyed. That way each test is completely isolated and there is no chance of side effects between browsers / environments. 


How can I direct my tests to the Selenium Box?

Running your tests on the Selenium Box is simply a matter of pointing the URL of your remote webdriver to the Selenium Box entry point. This is usually a one line change in a configuration script and therefore can be implemented really easily.


What browsers are supported?

Chrome, Firefox, Internet Explorer, Edge, MacOS Safari.


HOW do I run my tests on MacOS Safari?

In order to run tests on MacOS Safari, you need Apple hardware i.e. a Mac Pro. This is a legal requirements by Apple. The Apple hardware is then configured to be part of the Selenium Box system and seamlessly integrates into it. If a test with a desired capability Safari is sent to the Selenium Box Hub, it is dispatched to the Safari Node(s) and run there.


Can I use self signed SSL certificates?

Yes, Selenium Box also supports self signed SSL certificates.  


Can I take videos of my tests?

Yes. A video can be taken on a per test basis. The videos can then be easily integrated into the reporting system or CI system.


Can I watch my test running on the Selenium Box in real time?

Yes. Selenium Box provides a live view feature which allows to watch tests in real time while running.


Can I test older browser versions as well?

Yes. After a new browser or Selenium image is released to the Selenium Box, older browser versions are still available. Thus tests can be executed on the latest as well as older browser versions.
