Doubt in the testing of module 4

I am having difficulty in understanding how the testing of module 4 will work. I am running tests on interface implementation class and it is showing error of which I haven’t even worked on. If the testing will always fail without doing the task of, why they have asked us to test our code inside the milestone 1 itself. Can somebody explain the reson behind it? Does it mean that you cannot run Implementation class alone??

You should complete all the milestones first and then test your code. That would be better.

Hey @vipultyagi29 all the tasks are subconnected so if you are getting error by running just one on that time then probably you have made mistakes earlier in any subtasks so be careful about them
