Using Jenkins to run unit tests using the application Tessy, which provides a command line API. Tessy is running on a slave PC and Jenkins is sending commands from a Windows batch script. In the list of commands below, Jenkins will hang indefinitely when it attempts to run exec-test. The same sequence of commands entered in the Command Prompt on the PC executes correctly. If the exec-test line from the Jenkins script is commented out, all other lines will execute.

::Startup, path to file
tessyd --file "C:\ . . . \tessy.pdbx"

tessycmd connect

::Set up test files
tessycmd select-project "Project_Name"
tessycmd select-test-collection test5
tessycmd new-folder -test-collection "Daily Unit Tests %date% %time%"
tessycmd restore-module "C:\TMB_files\Module_Name.tmb"
tessycmd select-module Module_Name
tessycmd analyze

::Execute tests
tessycmd exec-test "C:\test5.tbs"

tessycmd disconnect

tessyd shutdown

What might cause that one command not to execute?
