DevTest Error: The chosen directory/file does not represent a valid DevTest Project.

Products

• CA Application Test
• CA Continuous Application Insight (PathFinder)
• Service Virtualization

Issue/Introduction

• Download MAR from Portal.    
• Open Workstation.    
• Choose Open and navigate to where your mar file is and select it.
• Get error "The chosen directory/file does not represent a valid DevTest Project." as in the below screenshot.

 

Environment

All supported DevTest releases.

Cause

Mar file not in the right format to open as a existing Project.

Resolution

This is working by design, because when you choose to open a Project you need to select a lisa.project file. The lisa.project is inside mar file and is independent from the Project it is opened in the Workstation. If you rename your MAR file with a zip extension and open you can see the file structure and can open it by selecting the lisa.project.

The DevTest Workstation takes the MAR files and extracts all the objects only for a New Project and not for the Existing Projects. Create a new project and select the MAR file which will open the MAR contents into the new project.
