Install Test Studio Across the Machines

The Scheduling setup in Test Studio is a set of services, which allows the communication between the Test Studio components on the different machines. Depending on their role in the configuration, the machines can run different editions of the product, and can be set up in various combinations.

This article guides you through the options of possible configurations. Check this Step-By-Step series blog post about setting up Test Studio Scheduling for running tests on multiple machines

Scheduling Components

The Test Studio Scheduling components are the Test Studio services and these need to be installed and configured on one of the machines, which will be used in the setup as a Scheduling and Storage server. Depending on the decision which machine will host which component, you can:


Test Studio installation must be configured from a Windows Administrator account.

Execution Servers

An Execution Server can be any physical or virtual machine with minimum installation of the Test Studio Run-time edition. Multiple Execution Servers can be connected to a single Scheduling Server to allow you execute multiple test lists simultaneously. Differences in operating systems and browsers between the machines running on the Scheduler and the Execution servers are allowed.

To register an Execution Server to the Scheduling service, you need to configure its Execution client to point to the running Scheduling service in the setup. The Execution client is part of each Test Studio installation - the Standalone, or Run-time.


Each Execution Server must be running the same version of Test Studio as the Scheduling Server.

Specific Requirements for an Execution Server Machine

Few things to consider when choosing an Execution Server machine:

  • Ensure that the Execution Server machine has sufficient disk space to store a copy of the project you schedule test lists from.
  • An active and unlocked user session is required to execute UI tests successfully. There are possible configurations and workarounds to help in setting up the Execution machines to keep the active session.
  • An exception from the last requirement is executing tests in Chrome headless mode - it only requires a logged user on the Execution machine.
  • If you plan to use 'Get Latest from TFS' on scheduled test runs, make sure the Test Studio Execution Server is running under an account with access to log on to the TFS repository.


If the machines have active firewall, ensure that the following ports are opened in both the inbound and outbound directions:

  • Scheduling Service: 8009
  • Storage Service: 8492
  • Execution Machine(s): 55555
