TestComplete command argument line

Hello,

 

I have a somewhat simple question that I am not too sure I understand fully.

 

The current situation:

I will be running an automated TestComplete project and its tests on a VM with the tested app installed.

I plan to use ' .bat ' (or similar) to initiate the call and automate the tests being run from TestComplete.

 

The question:

Is it better to use an extension with the TestComplete command line argument [file_name ] in TestComplete.exe [file_name /run...] or is it even necessary for the command to work if there is only one project?

 

For Example:

rem Without Extinsion
TestComplete.exe "TestComplete Project" /run...

or

rem With Extinsion
TestComplete.exe "TestComplete Project.pjs" /run...
