Mobile app testing is crucial as user retention is impacted by app performance, with 71% of users deleting apps that crash and 59% leaving due to slow responsiveness. Common issues include handling poor network connections and validating user input, which can lead to severe usability problems. TestElf offers comprehensive black-box testing on real devices, ensuring thorough functionality checks and quick turnaround to help developers release acceptable code without extensive documentation.

2. Why should you care?
• Profit for an app is dependent on the number of
users.
• A recent study by uSamp revealed:
• 71% of users delete an app that crashes.
• 59% of users delete an app for slow
responsiveness.
• You need to get it right the first time.

3. Bugs can happen to anyone
Costco
BlackBerry
Messenger
AMC

4. Here’s a common bug:
• Not handling bad network connections.
FaceTime Instagram
FaceTime displays an alert
that internet connectivity is
required—good!
Instagram shows a large
reload button on images that
cannot load, which has no
effect while the network is off
—bad!

5. Another common bug:
• Failure to validate user input.
Skype Path
Skype does not validate a
user’s birth date, so a
completely bogus date can
be entered.
Path has few restrictions for
usernames. The username to
the right is set to a large
number of blank spaces
followed by a period.

6. One More
• Usability and Control Issues
Skype SoundCloud
On iOS 7, apps have to ask
for permission in order to
access the microphone.
Some apps malfunction when
microphone access had been
denied. For example, in
SoundCloud, there is no way
to pause a recording without
microphone access. Tapping
on the pause button has no
effect (on right).
