Here follows this test's rationale:
:: First (ST#1) SubTest
1) Read coursera's items from its webroot html page
2) Write the items to a test text file
3) Copy items to a 'buffer' list
4) Empty items data from the stocking object
5) Read coursera's items from the given test text file, just writen out above
6) Assert equality of buffered items with current items read from the test text file in the previous step
:: Second (ST#2) SubTest
7) Recopy items to the 'buffer' list
8) Again empty items data from the stocking object
9) Refetch items now via a different method
10) Again, a second time, assert equality of buffered items with current items read from the test text file in the previous step
