The document discusses the crucial role of software quality assurance (QA) in software development, highlighting the differences in perspective between developers and QA teams. It addresses common mistakes made by developers, such as assuming user behavior and failing to validate input, while emphasizing the importance of process and communication in mitigating bugs. The author encourages better practices in coding, testing, and bug prioritization to improve overall software quality.
Software Quality Assurance: A mind game between you and devil
- 1. Software Quality Assurance: A mind game between you and devil
- 2. Hello! I am Tariqual Hassan I am here because I love to share my knowledge. So, let’s see what’s inside the box.
- 3. QA in Software Development What is quality? Who we are? Why we are doing IEE Glossary: Degree to which a system, component or process meets specific requirements and customer or user needs or expectations ISO Definiton: The totality of features and characteristics of a product or service that beat on it’s ability to satisfy specified or implied needs “Set of systematic activities providing evidence od the ability of software process to produce a software product that is fit to use” by G.Schulmeyer and J.McManus, Software Quality Handbook, Prentice Hall, 1998
- 4. 1. Transition period What Developers usually think?
- 5. It’s easy to code but it’s always difficult to code which is human readable.
- 6. I know how to code, I can keep up with the design so why you guys are here?- Devops
- 7. Why should user do this and that? I am designing the system, so they should just use it in my way.
- 8. QA guys are irritating day dreamers. They need not to code so they can come up with anything.
- 9. Okay, I will have fight with him and come up with a victory.
- 10. Okay it’s very difficult to apply this feature, let’s change it. Users can be convinced later on.
- 11. I didn’t do it and it’s not my job to fix this. Someone else will fix this.
- 12. 2. Transformation period How Devs are being transformed?
- 13. QA team interception ✣Found functional issues ✣Found UI issues ✣Found security issues ✣Found usability issues Okay too much issues…. Need to fix them all.
- 14. Project managers Dev team should fix the problems in a day, QA should finish testing in half day. Clients are waiting.
- 15. Software Development ecosystem QA: Things need to be done properly. Developers: Things need to be done in any way. PM: I need the product at any cost.
- 16. Dev’s Mind: I should provide a confirmation message before delete this record. Shouldn’t I give an alert before saving a content It work’s in my browser. UI can be better. Error message should not be propagated to user. A Dev’s Mind Dev’s Devil Mind: Ohh… it’s not your job. Users are not dumb. They should get this point. Why user use that browser. He should use like mine. UI is not my task. It’s the designer job It’s an error message. It should be visible to user. I have no time for a formatted message.
- 17. Common Mistakes Made By Developers Things need to be corrected
- 18. It works in my browser.
- 19. Input Data validation. Assuming that user will always input as intended.
- 20. Input Data verification. Making a checklist of what should be allowed and what should not be allowed.
- 21. Bloated Response: Page filled with high quality image and scaled down with the use of ‘img’ element. Files linked from the page(css and js) are large. Source HTML markup is complex and extensive. Page rendering should be slow. Consider the total cost for a request and response.
- 22. Deploying code without error. Ensure that no console error should be there.
- 23. Writing forking code: Developer may write codes to respond each possible scenario.The code becomes a heap of if statements, forking in all sorts of directions. If a new version of the browser has come, then management of those if blocks becomes very difficult.
- 24. Designing a site unresponsively: I am developing the site for the desktop .. why should a user visits the page from mobile?
- 25. Missing the accessibility feature
- 26. Creating a site that requires full refreshes of a page for each interaction.
- 27. Not thinking the security holes like sql injection, XSS, CSRF, HTTP, broken links, showing the directory structures etc.
- 29. Validation message text, color and position
- 30. Fails to distinguish among error message, warning message and informative message.
- 31. Forgot to handle the session timeout operation for different tabs.
- 32. Forgot to adopt the localization feature
- 33. Common spelling and grammatical errors
- 34. 3. Evolution and revolution I am changed now!!!
- 35. Realizing the cost of Bug Fixing A complex ide
- 36. Realizing the cost of Bug Fixing
- 37. Realizing the cost of Bug Fixing
- 38. Place your screenshot here Popup message Message without popup window title.
- 39. Place your screenshot here ToolTip Message Tooltip is not visible
- 40. Place your screenshot here Leaving Dev Message Meaningless Response to user
- 41. Place your screenshot here Let’s look at this
- 42. Our process is easy Develop Perform a Dev test Call for a short QA or pre-QA
- 43. Let’s review some concepts Agile Changes should appear at any point. So better code review will provide better maneuverability. Process Always follow a process. Make it tuned for a perfect fit to the team. Every process should NOT fit every team Bug Prioritization Learn how to give priority to a bug. Bugs should be prioritized. Fix the core issue Fix the core issue which causes the bug scenario rather than fix it in a temporary manner. Freeze your code Code freeze should be there before deployment operations Ethics Bug will be there no matter how better testing is done, but it will only acceptable if the bug is not in a certain path.
- 44. Probability for a bug Bugs Max Defects Max Client Reported Issues Development x x-1 - PreQA x-y - - Testing ((x-y)-z)=N - N-1/N!
