Portability Testing | What it is, How it Works & Examples

In today’s digital era, where software applications are accessed on an array of devices and platforms, ensuring their smooth functioning across various environments has become imperative. This is where portability testing comes into play. 

Portability testing is a vital aspect of software testing that validates the application’s ability to seamlessly navigate through different platforms, operating systems, and browsers. 

In this blog, we will discuss portability testing in detail, exploring what it is and how it works, with examples.

What is Portability Testing?

Portability testing is the process of testing how easily software or a product can be transferred from one environment to another. It measures the level of effort needed to move it from one system to another.

It is a type of non-functional testing. Also, it is conducted regularly during the software development cycle in an iterative and incremental manner.

Why is Portability Testing Important?

The importance of portability testing lies in its ability to identify and rectify potential issues related to platform-specific dependencies, hardware variations, etc. By addressing these issues, software developers and testers can ensure that end-users can access and utilize the application seamlessly, regardless of their chosen platform or environment.

Objectives of Portability Testing

The objective of portability testing is as follows,

• Check if the system can be moved or adapted to different environments.
• Ensure that the application looks and functions consistently across various operating systems and browsers.
• Validate if the system is ready for release on different browsers and environments.
• Identify any defects that were not caught during unit and integration testing.

How Do You Test Portability? – Manual And Automated

Portability testing can be performed using both manual and automated testing. Let’s discuss how it is done.

Manual Portability Testing

Manual portability testing involves testers executing test cases manually without the assistance of automated testing tools.

Here, the QA team will test the application on different platforms, operating systems, browsers, and devices to ensure compatibility and functionality. Let’s take a look at how it’s done:

Test Planning: In the test plan, the testers will define the scope of portability testing, including the platforms, browsers, devices, and other environments to be tested. Also, they will define the test objectives, test cases, and testing schedule.

Test Environment Setup: Then, the testers will have to prepare the necessary hardware and software environments for testing. Install the application on different devices, operating systems, and configurations.

Manually test the Portability: Now, the testers will manually execute test cases on various platforms (For example, Windows, Mac, Linux) to check for compatibility issues, UI layout, and functionality.

Manual Test Documentation and Reporting: Once the testing is done, testers will document the test results, defects, and observations and prepare a detailed test report highlighting the issues and recommendations for improvement.

Let’s understand this with an example.

Example of Manual Portability Testing

Imagine your development team has developed a web application, and they send it to the testing team (QA team) to check if the application is working as intended across all platforms in terms of functionality, responsiveness, portability, security, performance, reliability, and more.

Now, the QA team will interact manually with the web application on all browsers, platforms, devices, and versions. To do this, they will create test cases and add them to a spreadsheet where will they enter all the test case details like test case name, description, test data, test results, etc. 

Also, they will manually create a detailed report, reporting all the detected bugs and share their feedback with the development team. Once the development team fixes all the bugs, the QA team will test the application again and repeat the same process.

Manual portability testing requires a lot of time and resources to plan and execute the tests across diverse platforms and configurations. It is very time-consuming and expensive. That is why automated portability testing is the best choice to test the application’s portability and compatibility.
