Boundary Value Analysis-4

5.2 Critical Fault Assumption The Critical Fault Assumption is also known as the single fault assumption in reliability theory. The assumption relies on the statistic that failures are only rarely the product of two or more simultaneous faults. Upon using this assumption we can reduce the required calculations dramatically.    The number of test cases for our example as you can recall was 9. Upon inspection we find that the function f that computes the number of test cases for a given number of variables n can be shown as:                           …

5.0 Applying Boundary Value Analysis   In the general application of Boundary Value Analysis can be done in a uniform manner. The basic form of implementation is to maintain all but one of the variables at their nominal (normal or average) values and allowing the remaining variable to take on its extreme values. The values used to test the extremities are:    • Min ———————————— – Minimal  • Min+ ———————————— – Just above Minimal  • Nom ———————————— – Average  • Max- ———————————— – Just below Maximum  • Max ———————————— – Maximum    In continuing our example this results in the following test cases…

4.0 The Focus of BVA   Boundary Value Analysis focuses on the input variables of the function. For the purposes of this report, I will define two variables ( I will only define two so that further examples can be kept concise) X1 and X2. Where X1 lies between A and B and X2 lies between C and D.     A ≤ X1 ≤ B  C ≤ X2 ≤ D    The values of A, B, C, and D are the extremities of the input domain. These are best demonstrated by figure 4.1.        The Yellow shaded area of the…

1.0 Introduction   The practice of testing software has become one of the most important aspects of the process of software creation. When we are testing software the first and potentially most crucial step is to design test cases. There are many methods associated with test case design. This report will document the approach known as Boundary Value Analysis (BVA).    As the incredibly influential Dijkstra stated, “Testing can show the presence of bugs, but not the absence”. Although this is true we find that testing can be very good at first, if implemented correctly. For this reason, we need to know…

1. Requirements Traceability Matrix (RTM) A document showing the relationship/mapping between Test Requirements and Test Cases. Elements of RTM: a. Requirements ID b. Requirements Description c. Test Case ID d. Status [Open, Closed, Defer (Later), On hold] 2. Verification and Validation Verification is the process of confirming that something software meets its specification. Validation is the process of confirming that it meets the user’s requirements. Difference between Verification and Validation: Suppose, you are going to buy a pair of shoes having number 9 for you. You have chosen a pair and seen the tag with 9 written on it. This…
