Write test cases as if a 5 year old will do the tests.

My Sr. partner is the best when it comes to breaking things: 0: Entering non-numeric chars where numbers should go or invalid numbers such as 1,1.2 or 1.1,2 (fun fact, letters up to f will happily identify as numeric) 1: Extremely long text/numbers, special characters, 0s as divisors 2: Leaving 'required' fields blank 3: Using the back button in web apps Of course, there are some situations you can't predict. That's what users are for! :laugh:

and/or - cancel dialogs - close app (with click on "X") while db is in edit mode - kill app with task manager while someone is editing something - use special - non ascii - chars where it is not expected - simulate high load with endless read/write operations - change screen size/resolution to unusual values

Get some experienced testers to bash it hard - much better than test scripts IMHO - writing(and testing / maintaining test scripts) is often harder than coding the application

It seems like you're suggesting that getting experienced testers to thoroughly test a product is more effective than relying solely on test scripts. This approach can indeed provide valuable insights and uncover issues that might not be caught through automated testing alone. Your quote by Hunter S. Thompson highlights the importance of thoroughness and vigilance in testing to avoid pitfalls. Click Here

For at least 30 years, we have had/practiced the "5-year-old robustness test": Put the kid in front of a keyboard and a screen, and tell him: Do anything you want. If you make it lock up, and can show daddy/mommy what you did, you'll have an ice cream cone!" I know of a few ice cream cones awarded that way :-)

Why not edit a single record so it will work? I'm currently doing a project where we're rewriting an old VB6 application that used to use a dBase database. It's SQL Server now, but everything is not what you'd expect (everything is char(x), even bools, which have "Y" or "" (and sometimes "N"), except some ints, which are int or decimal(x,y)). Lots of magical numbers and strings too. Some fields even are like
"X X "in which the first X means "option 1 should be used" (whatever option 1 is), the empty second and third position means those options are off and the fourth X means option 4 should also be used (the software only uses four options, even though it's a char(10), also it's not always X, sometimes and option can be, for example, "S" for small or "L" for large, etc.). Anyway, finding a row you can use and writing a WHERE clause is a pain, so I just edit the top row so it'll fit my test/use case.Best, Sander Azure DevOps Succinctly (free eBook) Azure Serverless Succinctly (free eBook) Migrating Apps to the Cloud with Azure arrgh.js - Bringing LINQ to JavaScript

- Mind internationalization. Is your app translated? In how many languages? Serious work to do if this number is greater then 10. 2) How does the GUI looks like on a native Chinese (Traditional or Simplified)/Japanese/Korean PC? 3) Input long texts in various languages, with many specific characters. Special care when comparing and processing texts - in which culture? 4) Did you specify a culture when installing the app DB? If not, the SQL server default one will be used. Try different cultures/collations etc. 5) Input/use numbers in various cultures, alternating decimal/thousand separators etc. 6) Input/use datetimes in various cultures. 7) Set the date of the PC to 29th february in a leap year and test app functionality. 8) If you read text from disk/stream, create test files containing binary data (e.g. 0x1A/EOF - can your app read text beyond that byte?). Or create test files that have \r\n or only \n as end of line etc.

When I was working on an ActiveX control embedding a video stream into a web page (a long time ago when others were still working to prevent millenial apocalypse), we had a customer who used the "coffee cup" test - put a coffee cup down on F5 so it would continually refresh. Extremely harsh!

No, but I can list what I do: 1. Write use cases. What are users supposed to do with the system? From use cases, build test plans which not only test the system but teach the testers how to use it. 1A. Ideally most test cases start with new records and build upon them. For cases where that is not feasible, construct test records. Create scripts that will insert or revert the test records. If you have to hunt for test records, do it just once. 2. If you have role-based authentication and authorization, conduct each test in #1 for each role. 3. Most applications have pre-defined choices (radio buttons, drop down lists, list boxes). Test every possible combination. 4. This one is the hardest -- make as many totally illogical choices as possible. Try to do things out of order. Paste 10,000 characters into a textbox. Enter a string of special characters only. Save while missing mandatory inputs. Basically the "five year old" part. 5. Ask the end user testers to do as many weird things as they can think of. Trust that they will think of things you will never consider. I'm no longer surprised at how much basic error handling is NOT built into applications, e.g., the DB field is 20 characters but the text entry field is unlimited. #4 will identify things like that.

Brilliant! I need to offer more ice cream cones to my QA team.
