API Engine 3.0

As of Tricentis Tosca 12.3, the API Engine 3.0 supports OpenAPI 3.0.

Furthermore, you can now work with API connections directly in the XTestSteps of your API TestCases which allows you to easily adapt your test during run-time. Additionally, the new API Engine enables you to create Module Attributes for authentication details so you can steer them in your API TestCases.

With the newest version, we also support result count for attachments which enables you to verify the number of attachments an API message contains.

With Tricentis Tosca 12.3, you can create Module Attributes from CDATA messages that have XML or JSON content.

Distributed Execution

When using Remote Desktop Protocol (RDP) with Distributed Execution (DEX), you can configure the color depth and the resolution for agents.

You can also scale unattended execution by configuring multiple Tosca RDP Servers and limiting the number of RDP connections to them.

Import Subset

With Tricentis Tosca 12.3, an additional merging functionality allows you to merge a .tsu subset when you import it into Tosca Commander. That way, you can easily apply changes from one project, version, or branch to any other project, version, or branch.

Improved handling of different Tosca versions

We significantly invested in the Tosca database schema to enhance the handling of different versions. This change solves the incompatibility issues of using different Tosca versions on the same common repository, temporarily in the context of Tosca version upgrades. Or using Tosca Commander versions with different add-ins installed.

Mobile Engine 3.0

With Tricentis Tosca 12.3, Tricentis introduces a cross-Modules feature to decrease the effort of TestCase creation and maintenance. Now, you can scan an application on one device and use the Module for test automation on another mobile platform.


Furthermore, you can use the new macOS Mobile Configuration Wizard to configure your Mac directly from Tosca Commander.


The newest version of Tricentis Tosca supports image-based test automation for the Mobile Engine 3.0. With the new interface, you can create mobile image-based Modules in Live View.


SAP Engine 3.0

As of Tricentis Tosca 12.3, we add the possibility to scan and steer SAP dialog boxes.

SAP Web Extension 3.0

With Tricentis Tosca 12.3, you can now scan and steer SAP Fiori 1.60 controls.

Test Data Service

As of Tricentis Tosca 12.3, the Test Data Service is integrated with the centralized Tosca service configuration.

You can also configure OAuth 2.0 authentication for Test Data Service.

Moreover, Tricentis Tosca 12.3 allows you to create MSSQL repositories for the Test Data Service.


Tosca BI

With Tricentis Tosca 12.3, we improved the handling of our internal SQLite caching database. You no longer have to install external ODBC drivers. Instead, you define the connection to the caching database in the Connection Manager once; all Modules have direct access to it.

In your TestSteps, you can now easily select predefined connections directly from a drop-down menu. This helps if you want to rename existing connections and copy and paste them to other tests.

Tosca Commander

As of Tricentis Tosca 12.3, the traceability feature for single- and multi-user workspaces allows you to view the creation and modification information of all objects.
