  • 11. Software Testing: Discovering the Bugs You can‟t write software without introducing bugs! After initial coding you can expect one bug per 20 lines of code After thorough unit testing you can expect 1 bug per 1000 lines of code in the final release  1 line ~5 bytes, so 1 bug per ~5KB Steering Angle Sensor 8 bit microcontroller 7 Bugs* 32KB Code ABS Controller 16 bit microcontroller Bugs* 128KB Code 26 Airbag Controller 16/32 bit microcontroller 256KB Code 52 Bugs* EPS Controller 32 bit microcontroller 256KB Code 52 Bugs* Central Chassis 32 bit microcontroller 1.5MB Code Controller 308 Bugs* Engine Controller 32 bit microcontroller 4MB Code 820 Bugs* Hybrid Controller 3 x 32 bit microcontroller 10MB Code 2500 Bugs*18.05.2012 For internal use only Copyright © Infineon Technologies 2008.
