+-- The process will be shared accross multiple tests.
+-- This may well be a good idea because starting the process can be prohibitively expensive to do around every test.
+-- However, sharing the process means that tests could be sharing state.
+-- When using this function, it is important to implement some form of cleaning the state before every test.
+-- It is also important to use 'sequential' if some such state is maintained (and cleaned) so that the state is not cleaned while another test is running.
