Interoperability testing is defined as a software testing type, that checks whether software can inter-operate with other software component, software's or systems.
In other words, interoperability testing means to prove that end-to-end functionality between two communicating systems is as required by the standard on which those systems are based.
For example, interoperability testing is done between smartphone and tablet to check data transfer via Bluetooth.
In this tutorial, you will learn-
- What is Interoperability Testing?
- Different levels of Software Interoperability
- Why to do Interoperability Testing
- How to do Interoperability Testing
- Example Test Cases for Interoperability Testing
- Disadvantages of Interoperability Testing
- Difference between Interoperability Testing and Conformance Testing
There are different levels of Interoperability Testing, they are
- Physical Interoperability
- Data-type Interoperability
- Specification level Interoperability
- Semantic Interoperability
Interoperability testing is done because,
- It ensures end-to-end service provision across two or more products from different vendors
- The software product should be able to communicate with other component or device without any compatibility issues
The risk associated due to lack of Interoperability Testing are
- Loss of data
- Unreliable performance
- Unreliable operation
- Incorrect operation
- Low maintainability
The testing process for Interoperability testing includes following steps
Step 1: Launch Project.
- Define formalize statement of work and set up project management infrastructure.
Step 2: Set up test lab
- Make sure all required skill and automation tools are set up for test activities
- Use automation tools for minimizing test cases and re-use test cases
- Maintain a database of configuration files
- Record and analyze metrics for project
- Record configuration from unsuccessful tests for reference and analysis
Step 3: Develop test plan
- Write the Test Plan
- Define the test cases and procedures
- Set up necessary monitoring equipment for maintaining test logs.
Step 4: Execute test plan
- Execute test cases
- Work with test team to analyze root cause of failure
Step 5: Document Results
- Use test logs to record the implementation notes
Step 6: Free up resources and evaluate performance on the project,
- With the help of automation tools analyze the test results
The testing strategy for Interoperability testing include
- Connect two or more devices from different vendors
- Check connectivity between devices
- Check if device can send/receives packets or frames from each other
- Check if data is handled correctly in the network and facility layers
- Check if implemented algorithms work correctly
- Result ok: check next result
- Result not ok: Use monitor tools to detect source of error
- Report result in Test reporting tool.
The Disadvantages in Interoperability Testing are
- Determining root causes of defects
- Accurate Measurement
- Scalability of testing
- Network complexity
- Testing the Test Equipment
- Documenting Test Results and Learnings
- Inadequate requirements
- Software Engineering, Interoperability testing is nothing but to check whether software can inter-operate with another software component
- It ensures that software product should be able to communicate with other component or devices without any compatibility issues.
