Counting Strings

If you've done the Rapid Software Testing course, then you'll probably be familiar with the Perlclip tool, from James Bach. If not, its a useful tool for generating strings of test text. In particular I find the Perlclip Counter-string function to be pretty useful. Counterstring builds a string that indicates its own length. E.g.: "*3*5*7*10*" The last asterisk is the 10th character.

Now available as a Firefox Add-on!

I've taken the counterstring functionality and implemented it in HTML and Javascript. While this form does not do everything the original [and the best] does, It might be useful for it to be accessible anywhere via a web page. All credit for the usefulness of this goes to James Bach, all the bugs are probably my doing.

Thats right - its got bugs, like you don't have to enter a character for the 'mark' or it lets you use numbers for the 'mark'. Older versions did odd things in IE6 etc. There are no doubt many more bugs...

Display a string of length:

The character: marks the spot.



The String you requested is:

The string created has a length of:

  1. There's a good reason to allow numbers for the mark: some fields prevent or reject the entry of non-alphanumeric characters before other processing happens. Some do the same with non-numeric characters. So right away, I wouldn't classify "lets you use numbers for the 'mark'" as a bug, but a feature.

  3. Good initiative & very helpful :-)

    I like the error message "Go try a different browser" funny :-)

  4. Brilliant Peter.

    I hope you will add more and more to this very useful take on the tool by James.

Why you might need testers

I remember teaching my son to ride his bike. No, Strike that, Helping him to learn to ride his bike. It’s that way round – if we are honest – he was changing his brain so it could adapt to the mechanism and behaviour of the bike. I was just holding the bike, pushing and showering him with praise and tips.
If he fell, I didn’t and couldn’t change the way he was riding the bike. I suggested things, rubbed his sore knee and pointed out that he had just cycled more in that last attempt – than he had ever managed before - Son this is working, you’re getting it.
I had help of course, Gravity being one. When he lost balance, it hurt. Not a lot, but enough for his brain to get the feedback it needed to rewire a few neurons. If the mistakes were subtler, advice might help – try going faster – that will make the bike less wobbly. The excitement of going faster and better helped rewire a few more neurons.
When we have this sort of immediate feedback we learn quicker, we improve our game. When the f…

Thank you for finding the bug I missed.

Thank you to the colleague/customer/product owner, who found the bug I missed. That oversight, was (at least in part) my mistake. I've been thinking about what happened and what that means to me and my team.

I'm happy you told me about the issue you found, because you...

1) Opened my eyes to a situation I'd never have thought to investigate.

2) Gave me another item for my checklist of things to check in future.

3) Made me remember, that we are never done testing.

4) Are never sure if the application 'works' well enough.

5) Reminded me to explore more and build less.

6) To request that we may wish to assign more time to finding these issues.

7) Let me experience the hindsight bias, so that the edge-case now seems obvious!

Google Maps Queue Jumps.

Google Maps directs me to and from my client sites. I've saved the location of the client's car parks, when I start the app in the morning - it knows where I want to go. When I start it at the end of the day, Google knows where I want to go.
This is great! It guides me around traffic jams, adjusts when I miss a turn and even offers faster routes en-route as they become available.
But sometimes Google Maps does something wrong. I don't mean incorrect, like how it sometimes gets a street name wrong (typically in a rural area). I don't mean how its GPS fix might put me in a neighbouring street (10m to my left - when there are trees overhead).
I mean wrong - As in something unfair and socially unacceptable. An action, that if a person did it, would be frowned upon.
Example:
Let’s assume a road has a traffic jam, so instead of the cars doing around 60 mph, we are crawling at <10 mph.
In the middle of this traffic jam, the road has a junction, an example is shown here:
