Tests in C/C++ run shockingly fast. I ported an application from Ruby to C++ and the tests ran in well under a second when it was taking 10+ seconds in Ruby. Granted because of C++'s type system there were fewer tests, but it was fast enough that I kept thinking something was wrong.
Are you including the time to build/link the tests? This is especially true if you have a bunch of dependencies. Last time I worked on C++ tests most of my time was spent on getting the tests to link quickly. Managed to get it from 25 minutes to 1 minute. But I'd rather have spent that time actually writing more test cases, even if they took 10s to run.
Started a new job a few months ago and we’re writing Go - a bunch of the test suites I’ve built run in microseconds. Statically typed compiled languages ftw.
