What does the edge added to the call graph below represent, and how does it affect integration?(bottom-up or top-down both ok)

Solution

Solution:

The edge from J to B represent that J unit has made a call to B unit.

According top-down approach one more separate session is added that goes from J unit to B unit. The process of integration testing will not complete until this new session also get tested. This will increase the overall completion time of the testing process.
