I don’t think this is Julia-related, but maybe it is still related to some practice of coding in Julia (and I don’t know where else to ask).
Today I notice that lots of .cov files are generated in my Julia project directory. For example, if I have
test.jl, then there are many files like
test.jl.XXXXX.cov in the same directory, where
XXXXX is some 5-digit number. What are these files? Is it safe to delete them, or I should keep them? I suspected if they were generated by codecov, but I was not able to find relevant information.
