Branch testing

Question

if(condition1)
 dosomething1();
if(condition2)
 dosomething2();
if(condition3)
 dosomething3();

Is it full branch testing if I have two test cases in this example

1. condition1 = condition2 = condition3 = true;
2. condition1 = condition2 = condition3 = false;

Or have I misunderstood it? Trying to figure out the difference between branch and path testing. I get path testing so hope this is correct.

Answer 1

Branch Testing:

Testing in which all branches in the program source code are tested at least once.

Yes; you are performing correct branch testing, since all your branches are hit. In fact you can remove your second test case, since case 1 executes all the branches.

Obviously branch testing is less encompassing than path testing, since it's likelyhood of hitting dependies is low and as such, ought not to be your only form of testing.

Answer 2

If I understand what you are asking, then you may need eight test cases to completely cover the alternatives in the given code. For example, what if dosomething2() relies on some other state set up by dosomething1()? Your test cases would not catch that requirement.

Answer 3

Yes, you understand correctly. Branch testing is just "all branches are executed."
