Ignore directory wise instead of regex matching on module name for Mix's integrated coverage tool

Hello People,
I tried searching the web to look if I can ignore support files in my test directory using regex match on the directory itself rather than regex matching on module name couldn’t find any solution. Can you all help me with this?
Thanks,
Hakash

Define “ignore” please. To ignore for compilation (and all the related cases) use elixirc_paths: option to mix.exs’s project section.

Apologies for being naive.
I wanted to achieve ignoring the support files while running coverage test. To achieve so I heard this is a solution


I wanted to know if rather than write regex patterns to match on module names is there someway to ignore all the support files together?
For example in excoveralls you can ignore support files from being tested for coverage simply modifying the coveralls.json file.
