I recently update a site to 2.3 (with sample data enabled) no I find a lot of TestModules in the app/code/magento folder. I have 4 questions regarding these modules:
- Do they come from the 2.3 update or do they come from the sample data?
- Can I remove them?
- Can I git ignore them because they came after composer update?
- Is there a way so they do not get installed with composer?
