How to write unit tests in C++ relying on non-code files?
Java has in-memory file systems that are essentially geared for this exact use case, eg jimfs[0]. You create your filesystem and any files you need when your tests are starting up, and your classes talk to them rather than the “real” ones. Maybe a similar project exists for the C++ ecosystem?

Any library you would like to recommend to others as it helps you a lot? For me, mapstruct is one of them. Hopefully I would hear some other nice libraries I never try.
Recently been using JIMFS. Made my tests much faster and cleaner!

Working and unit testing with temporary files in Java
I use Google's JIMFS "Just In Memory Filesystem" https://github.com/google/jimfs in my unit tests and have been very happy. No need to clean something up that disappears as soon as the test is over. Let's you create unix or windows style filesystems and I've used it to test a disk space healthcheck because you can set a limit to the size of the filesystem it creates. Very flexible and easy to use.

Kotlin Money
I'm surprised nobody has mentioned Joda Money yet:
https://www.joda.org/joda-money/
From the same person that brought is Joda Time (ie, what the java time API was based on). I've used Joda Money a lot and it's great.
Honestly I prefer APIs that look like APIs and I think this trend towards inventing DSLs is a bad one. Rails works because there's a critical mass of people who have adopted what is essentially a whole new language on top of Ruby. A money library doesn't warrant a new language, it's unnecessary cognitive load.

[Production code] The previous dev thought it was ok to use floating point variables for money
Nice, I'd not heard of this before. Looks like it has more traction than Java Money (JSR-354).

Joda-money is more widely known and used for that purpose: https://www.joda.org/joda-money/
