This document discusses various topics related to software testing including agile development, testability, and tiny innovations. It notes that rapid iteration is important in internet industries to keep up with customer expectations. Testability refers to factors that make software easier to test such as controllability, observability, and understandability. Tiny innovations can help improve testing efficiency such as automating test case reruns with a single command instead of multiple manual steps. The overall goal is to enable high-efficiency, self-motivated, and self-learning approaches to software testing.

3. Agile
• What is the most important thing in internet
industry?
– Speed
• Eliciting requirements
• Implementation
• QA
• Deploy

4. Agile
• The problem is that the longer it’s been since your last
release the more pressure and anticipation there is
– Slow iteration
• Windows XP (2001) -> Windows Vista(2007)
• IE 6 (2001) -> IE 7 (2006) -> IE 8 (2009)
– Rapid iteration
• iPhone (2007)-> 3G (2008) -> 3GS (2009) -> 4 (2010)
• Kindle 1 (2007-11) -> 2 (2009-01) -> 3 (2010-07)
• Chrome 3 (2009-10-12)-> 4 (2010-01-25) -> 5 (2010-05-25) -> 6
(2010-09-02) -> 7 (2010-10-21)
• MRM 1.0 (2008-01) -> V2.0 (2008-11) -> V3.0 (2010-04) -> V3.5
(2010-11)

5. Agile Story
• On WordPress.com we deploy code to
production twenty or thirty times a day and
anyone in the company can do it.
• The most important thing isn’t necessarily how
perfect code is when you send it out, but how
quickly you can revert if you need to so the cost
of a mistake is really low, under a minute of
brokenness.
- Matt Mullenweg

6. How to speed up?
• No thrown over the wall software
– Transparency
• No heavyweight document
– This is for contractor who don’t know about for last few month
• No strict entrance and exit criteria with signoffs
– We work close with DEV and PM
• No sophisticated defect tracking process
– Sophisticated means redundancy
– Individuals and interactions over processes and tools
• Automation
– No sliver bullet

8. Tao of software testing
• 道可道 非常道
• 道、法、术、器
– 器 - Tool
– 术 – Test Case
– 法 - Knowledge
– 道 - Tao

9. Testability
• What is testability?
– If testing is questioning a product in order to evaluate it, then
testability is anything that makes it easier to question or
evaluate that product.
• The testability of software is determined by factors such
as:
– Controllability
– Observability
– Isolateability
– Separation of concerns
– Understandability
– Automatability

10. Why testability matters
• More testability, more test
• More test, less bug
• Less bug, more quality
• More quality, more $

11. Testability is not free
• “You can use it, so you can test it”
• What have we do?
– SNMP
– Lua

12. Tiny Innovation
• How to rerun a failed regression case?
– Version 1
• Open error.txt
• Type failed case id
• Save the error.txt file
• Python autoRegression_pusher.py
– Version 2
• $ echo ‘xxx’ > error.txt
• Python autoRegression_pusher.py
– Version 3
• $ rhm –c ‘xxx’
12

13. Tiny Innovation
• Process
– QA case review
• Technology
– Using ruby instead of python?
– SQLite helps?
– Virtualization helps?
• Working procedure
– How about auto rerun?
– How about prepare everything and let me send the
request?
– How about using a voice control rerun system

14. The Goal
• High-efficiency
• Self-motive
• Self-learning
14
10 years experience in
software testing!
NO! Just 1 year experience in
software testing repeat 10
times
