Statement and decision coverage

Statement Coverage is a traditional terget. Its deifne the coverage terget in Control flow Graph and write test cases to achive it. For example, Supose that we write and execute two test cases.

if 5=true than go to 6
//else if 5=false than go to 7

Test1: Follow paths 1-2-Exit
Test2: Follow paths 1-2-3-4-5-6-8-2-3-4-5-6-8-2-Exit.
here we can see in the test 2, we execute 2 loops and both time takes the true braches. and skips the false braches. so node number 6 is not executed so its not 100% statement coverrage


Otherhand The decision coverage is predicate nodes which always check condition for branching.  As an example we can use "if and else" "do while" and "switch " etc to coverage conditional branching to achive we need to write tests cases and execute it. 

sc 2 dc2

sc=2 and dc=3

SC = 2 and DC = 2

d) SC = 2 and DC = 2

SC=2 and DC=2

Hi.. The answer provided was sc2 dc 3 which I feel is correct as there are two nodes
SC>>>>
1. If interesting prog on tv
2. If crossword on newspaper

DC
1. Interesting prog on tv,
I. Yes
II.No
2 Newspaper
I.Yes

Hence proved

Hi,

The answer will be SC=2 & DC=3

Thanks
