Loop Testing

Simple Loops:- The following set of tests should be applied to simple loops,where 'n' is the max. no. of allowable passes:

1.Skip the loop entirely.

2.Only one pass thru the loop.

3.Two passes thru the loop.

4.m passes thru the loop where m< n.

5.n-1,n,n+1 passes thru the loop.

Nested loops:-

1.Start with the innermost loop.Set all other loop to min. values.

2.Conduct simple loop tests for the innermost loop while holding the outer loops at their min.iteration values.

3.Work outward,conducting tests for the next loop,but keeping all othe outer loops at their min. iteration count.

4.Continue until all loops have been tested.

Concatenated Loops:-Concatenated loops can be tested using the approach defined for simple loops,if the loops are independent.If the loops are not independent use the nested loop strategy.

Unsructured loops:-Redesign the loops so they are one of the above categories.

so,do you write test cases manually for all these strategies?or do you use any other technique?can you tell me

Dear madam,There is no so much need of graph for loop testing. Loop testing is different than data flow testing. For data flow testing graph is must. For loop testing the comments posted earliar is more than sufficent.
