4-4) Embedded software test method using orthogonal array
MOSTEST method (Method using Orthogonal array for Software Evaluation Testing)
Feature / Effect
Some creative thinking
in the orthogonal array
Realizes 100% cover rate (2 factor combination test)
using orthogonal arrays based on Taguchi method
with excellent time efficiency and accuracy Secure discovery of
Overview of MOST's software verification tool
1. Enter the relationships between condition
factors and configuration factors
2. Enter simple factors and their levels
state transition paths
1. Enter state transition relations
2. Clarifies needed tests (automatically)
3. Enter factors and their levels
Automatically finds the optimal orthogonal array from the
arranged 1909 kinds (variants of L256, L128, L64, L32, L16), and automatically
generates an orthogonal array (describing factors and levels)
for bug verification
• 2 level system L16 max 16 factors, L8 max 25 factors, L4 max 32 factors, L2 levels max 254
• Simultaneous processing possible for 4 kinds of factor ( One of L16, L8, L4 or L2)
• Level of configuration factors is one of L16, L8, L4 or L2
(level # of condition factor 1 * level # of condition factor 2 * level # of condition factor 3 * level # of condition factor 4* level # of configuration factor <= 256View entire presentation
