Unit testing is not passing

i got stuck in module 1 and main thing is i don’t know where i did mistake or where should i work, all files are running successfully on terminal but test casing is not passing for that 3 files, milestone 2,3 and 4 in module 1, what can i do now ? please suggest!!

this is the screenshot of unit testing.

Read the Task instructions in the script carefully. Have you done all that is needed?
Google to see if you can find the correct way to do it.

I have done all commands that was needed, it is even running on terminal… I guess it is the problem of generalized path, can you explain me how can I get rid of it please.
