Pioneered comprehensive testing standards for QNX RTOS diagnostic systems, improving code maintainability and reducing system errors

Overview

Improved testing efficiency by establishing comprehensive standards for QNX RTOS diagnostic systems. Enhanced code maintainability using S.O.L.I.D. principles in C++

Problem

Inconsistent testing practices across diagnostic systems. High error rates and difficult-to-maintain code

Constraints

QNX RTOS specific testing
Medical device standards
Precision imaging requirements

Approach

Developed automated test suites using Lua and shell scripting. Created precision imaging analysis tools. Established comprehensive testing standards that became company standard

Key Decisions

Use Lua for test automation

Reasoning:

Lightweight, easy to embed, good for rapid test development

Apply S.O.L.I.D. principles

Reasoning:

Improved code maintainability and testability

Tech Stack

C++
Lua
QNX RTOS
Shell Scripting
Test Automation

Result & Impact

Significant decrease

Error Rate Reduction
Company-wide adoption

Testing Standards
Precision imaging analysis tools

Tools Created

Pioneered BioFire's test engineering role, establishing standards still used today

Learnings

Lua excellent for rapid test development
S.O.L.I.D. principles improve testability
Establishing standards early pays dividends
