I know why I am a tester. My driving force is my curiosity: I want to know how things work, why they work and why they don't.

Apr 18	comment	Recommend a Good QA Book Could you comment on what you have found particularly useful or interesting in the latter two books?
Mar 31	comment	Testing in Open Source Projects +1 for very practical criterion for selecting OSS project that is worth tester's effort.
Mar 25	comment	What is really tested in an integration test? I added a link to analysis of bugs found in integration. This is work in progress, so any feedback is welcome.

Mar 12	comment	How do people express their ability to test software? I'm not necessarily convinced that automation output per se can demonstrate your skills. You must see automation always in the context of the problem you've tried to resolve. Anyway, automation is just one of the tester skills. If you look for what makes up a tester's portfolio, see related questions here and here + See "Realted" section on the right :-)
Feb 19	comment	Could I get a job by sending a list of bugs found in products of potential employer? +1 for the link. I've learned that the task of the tester is beyond test design and bug finding. It's also about creating tools and datasets for devs, PMs, and other tests to verify bug fixes, and test some areas themselves. It's about doing it quickly, so with the right tools.
Feb 19	comment	How to test data migration procedure? We may have no budget/time to try the tool, but I would like to understand the problem it addresses. We have implemented migration tool. What edge cases will be visible in its code and not in the schema? What edge cases the tool can help us discover here?
Feb 19	comment	How to test data migration procedure? Thank you. Can you point me to the mentioned case study? The only page I found has very limited information. A white paper on that, linked here, is not available.

Feb 19	comment	How to test data migration procedure? Thank you. Can you comment on sanity tests in the context of migration? A critical subset of previously performed tests just to make sure everything works?
Feb 19	comment	How to test data migration procedure? Very clear now. Thank you!
Feb 19	comment	How to test data migration procedure? Can you illustrate per-customer settings with an example? Do you mean that migrated DB and filesystem may not cover all client-related data in a production system?
Feb 19	comment	How to test data migration procedure? @Sam_Woods, Thank you for sharing your experience. By cleanup process you mean bringing production data to the previous state?
Feb 19	comment	How to test data migration procedure? Maybe I was not clear here. 1) I've installed DB with new data schema (the same where I will migrate data to). 2) I've populated new schema with load of artificial data from worst case scenario I defined. Artificial data are of size bigger than data that I will migrate. 3) I evaluated query response time for those artificial data. Do you mean migrated data will have some statistics that artificial data does not have but still can impact performance negatively?

Feb 18	comment	How to test data migration procedure? I tested destination system performance with artificial data from worst case scenario (that is worse in terms of entity numbers than existing production scenario). Why would I have to verify performance again of system with migrated data?
