Fail compilation #NeverStopTesting

As you probably know, I have this special ability to brake things. No matter what the app is or how fantastic the website seem to look like – everybody use it – I’ll brake it for sure. This is me. The tester.

I collect all of those in my Gallery, sometimes post on Twitter with a hashtag #NeverStopTesting, but from time to time I my collection is so large, that
I need to organize it.

Treat this post, as a trophy gallery, please.

Language translations are my favorite. From time to time I change language on my phone, in order to learn new words. It’s great to observe how various websites and applications go crazy when I switch the language back to Polish πŸ˜€

For example Facebook couldn’t handle it and crashed.

Screenshots below could be funny for my Polish readers. Extra!


I like to be well informed when something goes wrong. The sign below means “Error occurred” in Polish πŸ™‚

Sometimes it is just wrong. Entirely wrong…

If you are a fellow tester – share your findings down below or post them as a comment on Twitter πŸ™‚ Cheers.

UI goes first. Mobile Testing.


You’ve probably heard about usability testing. It’s one of non-functional testing ranges.
A quick reminder about non-functional test types below. Usability is the one that we will be focusing on now.


Why testing mobile apps, when Usability comes first is so important?

Because form UX point of view application should be:

  • attractive
  • functional
  • useful
  • fun

Application should make the user happy – not frustrate him. How is it possible to be done? By providing great, clean UI. No matter if we are talking about iOS or Android applications – rules are similar. Keep It Siple Stupid.

What is more, you’ll have to keep two facts in mind:

  • Mobile customers are intolerant and fickle. (You know you are). If your app isn’t a knockout on first impression, it’s probably going to be deleted or will be forgotten on their smartphones.
  • 50% of the users expect, that an app is ready for use under 2 seconds

Silicon Valley analyst Andrew Chen attests that the average app loses 77 percent of its users in the three days after they install it. After a month, 90 percent of users eventually stop using the app. In addition, research by Mobilewalla revealed that users eventually delete 90 percent of all downloaded apps. Make one wrong move that angers or frustrates users – and chances are your app will be deleted.

We could say that testing mobile app is one of the most stressful jobs on the planet – if you don’t succeed – the app doesn’t as well.


Even if the UX design is correct during your testing remember about following check list:

  • get familiar with you users (by research, Google Analytics, Twitter etc.)
  • mind screen size (device fragmentation)
  • check on proper OS versions
  • select correct device types and brands (brand fragmentation)

Remember, that in mobile testing, more than anywhere else – tester is in charge – not only by keeping the initial design in shape through all development and testing process, but also by protecting user’s needs.
