Automated Testing Tool for Unreal Standalone Builds (no codebase access)

What third party testing tools work with Unreal Engine builds?

My team won’t have direct access to the project codebase, but we would still like to use some form of automated testing.

Can you use external software tools to test Unreal builds without putting in ‘hooks’, some type of plugin or api into the project codebase?

Can anyone please help me out?

I can’t find any info about testing an Unreal standalone debug / development build without accessing the code.

I know you can use Gauntlet but that has to be configured in the project that I’m trying to test and I will have 0 access to the code and the dev team is not interested in using Gauntlet.
