In Mac machine, double clicking the Workstation.app in DevTest_Home/bin folder not launching Workstation.
Tried in Terminal window by going to the DevTest_Home/bin/Workstation.
Release : 10.x on macOS Big Sur, Catalina,.
Component : CA Application Test
Corrupted install caused the issue.
JAVA_HOME and LISA_JAVA_HOME not configured to use specific Java
Specifying JAVA_HOME and LISA_JAVA_HOME to the available Java in the bash/zsh profile on machine and reinstalling DevTest on to a clean new folder will resolve the issue.
