Build Failing when adding doctest in it. #10268
Description
What would you like to share?
I found some file build fails when you doctests in it. Also, those file have very low cover. there could be various reasons for these failures. Most common is Incorrect wrong output formatting. So, fix this we need to change the code to add doctests in file and may it increase the cover of files. Also, the maintainer says don't change code and Add doctests in the same PR because of its make complicated make different PR if you want to change.
