As a rule of thumb, unless a customer requests functional testing, you should opt to use either in-circuit testing or flying probe testing to determine that your product is functional. Which method you choose should be determined by several aspects:
1. Development Timeline
2. Production Volume
3. Budget
4. Design Complexity
