What is SDK?
Software development kit
<Developing multi-platform mobile SDK, what can go wrong with quality?>
- a set of software development tools that allows
the creation of applications for a certain
software package, software framework,
hardware platform, operating system, or similar
development platform.

Why am I talking about testing
mobile SDK?
• I didn’t find anything similar in internet
• You can’t know what you’ll test on your next
job
• Your testing paradigma can be turned upside
down
• But, best testing practices can be used
anywhere, “I guarantee it”

8. Киев 2017
What did we start from?
• No QA processes
• Lots of bugs discovered by clients
• Testing only SDK is not enough, but you won’t
test the whole customer’s app games because
it’s time-consuming
• Tricky third-party issues
<Developing multi-platform mobile SDK, what can go wrong with quality?>

9. Киев 2017
Actually, it wasn’t so bad
• Devs did 5 releases and still alive (have clients
and gain money)
• Devs are concerned about quality a lot, that’s
good
• Fast and dedicated support
• TDD

10. Киев 2017
Common problems for mobile
apps and SDK
• Fragmentation hell
• Network-related problems
• Mobile architecture issues
• OS version diversity
<Developing multi-platform mobile SDK, what can go wrong with quality?>

11. Киев 2017
Specific problems you may face
testing mobile SDK
• Your testing is far from the “end”
• Unexpected bugs in prod (long to fix)
• Third-party issues
• Your sense of beauty is not important
• Some types of testing are really not needed
<Developing multi-platform mobile SDK, what can go wrong with quality?>

12. Киев 2017
Problems you may face - you are
not done yet!
• Your SDK will be integrated into completely
another product
• It doesn’t mean it will be integrated correctly
• Key focus - interaction of your SDK with the
app

13. Киев 2017
Problems you may face - long
shipping process
We are shipping binary packages and customers
can take weeks to update to the recent version
...and then upload their app to the App
Store/Google Play
<Developing multi-platform mobile SDK, what can go wrong with quality?>

14. Киев 2017
Problems you may face - third-
party issues
• E.g. Facebook bug
• or recent Twitter update
• We have 7 more invite channels :-O
• And a lot more features...

15. Киев 2017
Problems you may face - some
testing types are not needed
• Your sense of beauty is “neglected” as
customers will (hopefully) develop their own
UI
• Some testing types are not needed (e.g.
accessibility)

16. Киев 2017
Integration… is not that you
were thinking about
• Game devs usually integrate their game with
12-16 SDKs
• Integration bugs on each particular game can
be different
• Bugs differ according to platform (not only
iOS/Android, but also Unity, Cordova)
