Run specs from install folder?
- Currently, no testing is done on the install folder.
- Configure/build & testing both take far longer than install
- spec tests normally run directly in their repo (ruby/spec)
GitHub PR 2160 https://github.com/ruby/ruby/pull/2160 runs the spec suite from the install folder for the three windows builds. All passed, and the tests were run parallel.
Given that the purpose is to create a functioning install folder, maybe a first step would be runnig specs from there?
