Introduction – Introduction of Internet of Things?
The Internet of Things (IoT)
is about extending the power of the internet
beyond computers and smartphones to a
whole range of other things, processes and
environments.
IoT allows businesses and people to be more
connected to the world around them and to do
more meaningful, higher-level work.

Internet of Things- Value Chain…continued
 Device layer- Support the wide variety of sensors, devices,
and gateways support remote monitoring and
management
 Communication layer- Provide a reliable network for
capturing and controlling sensor data
 Cloud Services layer- Analysing and interpreting the data
at scale through cloud technologies and platforms
 Application layer- Manage the collection, processing,
analysing, and persisting of the large volume of sensor
data in near real time
 Security cross-layer- Provide for sensor data management,
application integration, and device management.

Usability Testing
1. Be assured that all
devices connected into
the network
2. Displaying data,
processing data, pushing
job tasks from the devices
should be tested
thoroughly
Connectivity Testing
1. Communication between
the device and its operator
2. The common types of
communication protocols
include Wi-Fi, Thread,
ZigBee, Bluetooth, RFID,
and NFC.
Security Testing
IoT devices are equipped with IP Addresses &
have the ability to transmit data over the
network
2. We need to check if the data is encrypted
when getting transferred from one device to the
other
Password & Credentials
Data Interferences
Constant Updates
Secure Booting(i.e., User authentication)
Device authentication
Firewalls
Testing Types…

Compatibility Testing
1. Multiple Architectures- Simple &
Complex
2. Check IoT cloud Platform- for
effective usability
3. Generate structured or
unstructured data to send to
Cloud
4. Test numerous operating
versions, browser types & versions,
generations of devices,
communication modes.
Testing Types…
Pilot Testing
1. Most important testing, IoT
developed system is exposed
to a limited number of users
in the real field
2. Helps in early detection of
bugs in the System
3. Verifies a component of the
system under a real-time
operating condition
Performance Testing
1. Consider a few aspects like
Network latency & its Bandwidth,
packet loss, a huge number of
simultaneous users
2. Focus should be on Simulation,
Scale, Amount of Data, Protocols,
Requests/ Responses

Scalability Testing
1. Scalability ensures that an
application can handle the
projected increase in user traffic,
data volume, transaction counts
frequency
2. Focusses on the performance of
2S/w, H/w, network, CPU/memory
usage
Testing Types…
Upgrade Testing
1. Involved testing an upgrade
to existing software
2. Ensure that all the upgraded
components in the value chain
are working efficiently during
the regression
Regulatory Testing
1. Determine the compliance of a
system with internal or external
standards
2. Include the regulatory
requirements at the start of
development cycle
3. Determines the compliance of
IoT applications with privacy
regulations

required & test
automation approach
2. Human resource
management
3. Infrastructure
management (S/w,
H/w, Labs, Simulation)
4. Address
Interoperability,
standards, protocols
1. Perform types of testing
2. Perform security testing
at each layer
3. Perform
interoperability testing
across IOT
implementation
4. Perform user centric
testing to make sure IoT
solution is risk free
