Work with TestCase-Design

The Tosca TestCase-Design section is an AddIn that enables you to put your test cases into a logical structure, and provides an overview of which test cases you need to cover the Requirements you have defined. TestCase-Design allows you to plan and specify your test cases wisely in order to maximize test coverage and reduce effort and redundancy later on.

Use the TestCase-Design section to do the following:

Install the TestCase-Design AddIn

The Tosca TestCase-Design AddIn is installed by default as part of a complete Tricentis Tosca installation. Therefore, you need a valid license to be able to work with the Tosca TestCase-Design section.

The directory %COMMANDER_HOME% contains the relevant TestCaseDesign.dll file.

Activate/deactivate the TestCase-Design AddIn

You can enable or disable the TestCase-Design AddIn via the Tosca Commander Options dialog under Project->Options-> TestCase-Design. The TestCase-Design AddIn is enabled by default. If you disable it, Tosca Commander does not obtain a license for the TestCase-Design AddIn during start up, so the TestCase-Design AddIn starts in read-only mode. This means that you can see any TestSheets that have previously been created, but you cannot make any modifications to them.

Restart Tosca Commander for your changes to take effect.
