Agenda Risk Management QA & Testing Bug Tracking Tools

Risk Management Risk Assessment Risk Control What things might go wrong badly? Cost, schedule or quality? Risk Control Take the correct action to handle it? Maintaining the Top Five Risk List Bug Triage

Risk Assessment ideas… I discover a requirement that I can not figure out how to implement I don’t have time to finish the code, I have too many other projects to do I can’t finish all the planned features in the time allowed I lose the program’s source code due to a hardware issue My code quality is too low to share without embarrassment ….

Risk Assessment

Risk Control Get things done!

Maintaining the T5 Risk List The goal of the Top 5 risk list is to give you an idea where you can immediately and easy review the most serious threats to your project ….

Bug Triage Prioritizing bugs based on their seriousness and deciding what to do about each one Fix what really need to be fixed By Design Duplicate Postponed Not Reproducible Won’t fixed Reassigned Fixed

Bug Tracking Work Flow A tester find a bug and report it The bug is assigned to a manager for initial triage The manager resolve it or assign to a developer Resolved bug returned to a tester The tester either closes the bug or reopen it with additional information or comments which start step 2 again

QA & Testing Type of Software Test QA for Lone Wolf Build a Test Network

Type of Software Testing Unit testing Chapter 5, by function or component Functional testing Walk through with specifications? Conformance testing Match industry spec? ex. XML format match W3C XML.. Compatibility testing Different OS, HW… Performance testing Check the application performance is acceptable to user

Type of Software Testing Stress testing How app fail when subjected to excessive stress Regression testing Test that were passed by previous build of the software Smoke testing Running “quick and dirty” tests that exercises major features .. Have to wait till next build if failed Black-box testing Focusing on external interfaces, (most are QA jobs) White-box testing Internal behavior of component is tested , just like unit testing

QA for the lone wolf Use unit test Most company have 1/3 manager & architect; 1/3 develops; 1/3 testers Use unit test Create a list of critical requirements Set code aside for a few days before performing functional tests Get someone don’t know your app to test Keep a written list of requirements Use bug tracking system Be sure to check absurd input If you think something might go wrong while coding, enter it as a bug in you bug tracking system. This will help you to remember Treating bugs as learning experience, not a threat to your coding skills

Building a Test Network Some advice from the author Buy preassembled machine, name brand, serious development hardware Skip tapes Store data separately Keep drive image Use virtual machines Use KVM switch ( many company do this) Get your own domain Use a firewall Set aside test machine & use mix of machines Set aside a build machines

Bug Tracking Tools Choosing a bug Tracking Tool Using a bug tracking tool

Choosing a bug Tracking Tool Cost (tool cost / license ..)? Multiple platform needs? / web based or other interfaces Send notification, distinguish or feature request? Integrate with other management tool? Where does the tool store information? What do you NEED from here?

Using a bug tracking tool What happen What the tester thinks should happen instead Steps to reproduces the problem
