Internet of Things

• Mobile: It can help you to access the compatibility of mobile platforms like Android and iOS.

• Software versions: It is used for the verification of the compatibility between the

various software versions and the IoT software application. Version testing is further

divided into forward and backward testing. The former is used for the verification of

the behavior of the designed IoT software or hardware by using the latest versions of

software or hardware versions. On the other hand backward compatibility is used for

the verification of the behavior of the designed IoT software or hardware by using older

versions of software or hardware versions.

Compatibility testing can be performed via the following two tools.

1. Compatibility of operating systems with virtual desktops: Such a tool is required for the

execution of multiple OS applications which serve as virtual machines. You can connect

as many systems as you want and run the comparison of results.

2. Compatibility of browser testing with BrowserStack: Such a tool is required by IoT

testing for testing the same IoT application with various browsers.

In order to perform compatibility testing, consider the following.

1. At the beginning of compatibility testing, you have to specify all the platforms and

environments which are to be used with your IoT application.

2. Thorough knowledge and understanding of the IoT hardware, software, and platforms is

necessary for the tester to know in order to work around the behavior of the application

while dealing with multiple configurations.

3. Various devices, networks, and platforms should be tested by setting up an appropriate

environment which can determine the performance of the IoT application with various

configurations.

4. The bugs should be reported so they can be fixed. Perform a re-test for the confirmation

of defect fixing.

Performance Testing

Performance testing makes sure that applications in the IoT infrastructure perform correctly

within the estimated workload. Only the functionality and features of the IoT software are not

important, its usage of resources, time period for creating a response, and reliability are also the

key factors for performance. The testing is not focused on the identification or fixing of buys;

instead, it emphasizes to reduce the performance bottlenecks.

Mainly, performance checking is used to assess three aspects of IoT software.

1. What is the speed of IoT application that is, how rapidly will it create a response?

2. What is the extreme workload which the IoT software can manage?

3. How stable is the IoT application with constantly changing user loads?

Before going further, it is important to understand the need for performance testing.

It is executed to oer meaningful information to the stakeholders in terms of the scalability,

stability, and speed of the IoT application. Additionally, it can oer insights about what are the

steps which can enhance the IoT solution before its public release. Lack of performance testing

can make the IoT software work considerably slower when a lot of users are accessing the IoT

system at the same time. On a similar note, it helps to identify poor usability and irregularities

between dierent OS.
