Answer - When you say "IA", are you referring to interface agreements?
You need to refer to "V" model of testing.
Business requirements are validated by user acceptance test cases.
System requirments/Interface agreements are validated by system test cases.High level design is validated by integration test cases.Low level design/code is validated by unit test cases.
- Prepararing and reviewing these documents should begin early in the life cycle.
- Reviewing and ensuring that test cases are correct/complete before test execution is key part of static testing (reviews, inspections.)
