CYPRESS PNSQC (15-17 Oct. 2001) 7 Software Environments Internet & Windows  Compatibility with different servers running different OS  Servers may be busy or unavailable  Large amount of memory locally, storage locally and storage on servers  Tools for testing memory leaks, measuring test coverage and automating tests exist Scoping The Effort Embedded  Runs on a single device  Playing music requires real- time limits of msec.  A limited memory & storage  Few off the shelf tools

CYPRESS PNSQC (15-17 Oct. 2001) 8 Possible Team Organization  Test & QA team per discipline –Software –Electrical –Mechanical  Single combined team  System testing encompasses all disciplines Scoping The Effort

CYPRESS PNSQC (15-17 Oct. 2001) 9 Organization Of The Team  Test lead  Electrical, mechanical & software debug - designers  Embedded software - 1 software test engineer  Windows & web software- 1 software test engineer  Internal mechanical & electrical - 1 mechanical test engineer  EMI & UL tests - 1 environmental test engineer Scoping The Effort

CYPRESS PNSQC (15-17 Oct. 2001) 10 Tools  Windows and Internet - commercial test tool  Embedded test tools developed internally –This is a full development effort –It needs adequate planning, time & resources  Scopes, in circuit emulator, etc.  Time at EMI and UL facilities will be rented Scoping The Effort

CYPRESS PNSQC (15-17 Oct. 2001) 11 The QA Plan  Configuration management –Software / hardware changes –Typical change –Hardware description languages –Product / web configuration  Issue tracking

CYPRESS PNSQC (15-17 Oct. 2001) 12 Typical Change  Requirement for monitoring battery usage discovered  Add a gas gauge chip –Electrical & mechanical change  Add software driver for the chip  Add software to display status on GUI  Configuration management vitally important QA Plan

CYPRESS PNSQC (15-17 Oct. 2001) 13 Hardware Description Languages  Blurs the line between software and Hardware  Source easily managed  Graphical environment - same issues as Windows  Configuration management a “software thing” QA Plan

CYPRESS PNSQC (15-17 Oct. 2001) 14 Product / Web Configuration  Web content changes quickly  Software on PC changes more slowly  Firmware in device changes more slowly  Address in product & tests plans QA Plan

CYPRESS PNSQC (15-17 Oct. 2001) 15 Issue Tracking  It’s a software problem  Investigation shows electrical problem  Fix it in software  Must have a common tracking system QA Plan

CYPRESS PNSQC (15-17 Oct. 2001) 16 The Test Plan  Tools  Hooks into the product  Reviews  Compatibility tests  Host / device tests  Stress tests  Power tests  Electrical & mechanical tests  Schedule –Schedules & staffing levels - Cem Kaner & Kathy Iberle papers

CYPRESS PNSQC (15-17 Oct. 2001) 17 Tools  Web & windows tool selection  Embedded tool development  Buy or rent tools for electrical and mechanical tests Test Plan

CYPRESS PNSQC (15-17 Oct. 2001) 18 Hooks Into The Product  Affect the test approach  Warning and status easier to test  RS232 vs Bluetooth Test Plan
