4 Course Goals and Outline Mastering Software Quality Assurance: Best Practices, Tools and Techniques for Software Developers, Murali Chemuturi introduction to the software engineering testing process, describe the quality assurance process and its role in software development. The student will be instructed in a variety of testing techniques, methods, and tools. Syllabus-Fall-14.html Sam Siewert 4

5 PRClab - Linux Option #1 Use PRClab, prclab.pr.erau.edu via SSH Recommend Putty connection with SSH and X11 forwarding Code Development (GCC/g++, Make, etc.) - Debugging C/C++ Source Code using DDD ( ) Verification and Validation of C/C++ Implementations General Linux System (RHEL 6.5) Option #2 Use Virtual-Box Linux with Centos 6.5 Install of Ubuntu LTS (Both Supported) Must Have Windows, Macintosh or Linux Personal PC ux-development-getting-started.pdf Sam Siewert 5

6 Why Work with Linux and Virtual Box From Mobiles to Super-Computing to Datacenters Embedded/Mobile Google Tianhe 33+ Pflops From Android Mobiles to GIS and Digital Video Services Huge Value in Open Source Drivers, Tools, and Applications Speeds Up Time to Market Oracle Virtual Box Great Cross OS Test Environment Sam Siewert 6

7 How We ll Do It 1/3 Theory Lectures/Reading (On-going) Lectures related to MSQA Textbook and Instructor s Experience History of SQA and Current Best Practices Discussions 1/3 Practice PRClab or VB-Linux Linux Coding (C and C++ or Java if you wish) Modification to Add Features, Debug, Inspect, Fix, Regression Test Original Implementations, Walk-throughs, Design Validations 1/3 Project Group Project to Take Application through SQA Life-cycle Final Assignment Sam Siewert 7

8 Administrivia Introductions Instructor (Office Hours) - Fall-2014.pdf Students (Introductions) Please do Collaborate, but cite well! Policies - ERAU Blackboard Primary Assignment Management Tool - Access via ERNIE - Backup to Mercury Website - Course Information list (please sign up on sheet being passed around) Lecture Notes at Will post on Bb as well Must have PRClab account OR VB-Linux I highly recommend both if possible, but PRClab is sufficient Sam Siewert 8

9 Linux Skills Introduction Session August 24, 2004 Sam Siewert

10 C Code Unit Development and Test Examples-Crypto.zip Basic Substitution and Transposition Cypher Code (e.g. Enigma) Download, unzip, make, debug with ddd Barry Boehm Are we building the right product? [validation]; Are we building the product right? [verification] Does it Work? Verification was it properly constructed and logically or mathematically correct? How does it Work? Limitations? Does it Meet Requirements? What are the Requirements? Validation does it meet intended use requirements? Is it Reliable? User friendly? Sam Siewert 10

11 Next Time SQA History (read Chemuturi Chapter #1) Come to Class Prepared to Discuss Gurus (e.g. Edward Demming, Grady Booch, Barry Boehm, Edward Yourdon, Tom DeMarco, ) Organizations for SQA - Process and Validation of Process - Assignment #1 Discussion I will Post Every Other Wednesday, We ll Discuss, Due Following Week on Friday Late Assignments 10% Penalty for Monday Turn-in, After Monday, only with Instructor Permission Sam Siewert 11
