Interoperability testing is defined as one of the types of non-functional testing that ensures the interoperability testing of the software. But before proceeding ahead with interoperability testing, let us first understand the meaning of the word interoperability.
What is Interoperability?
Interoperability is defined as the ability of a system to work and interact with other systems and applications. It is the ability of a system to provide and accept features from other system or software. The interoperability quality provides flexibility in interacting, sharing and exchanging data and information with other system, without interrupting the feasible functionalities.
For instance, let us take an example of a banking application system. A banking application needs to interact, exchange and share data and information with the application of other bank or same bank but different branch or any third party for the purpose of financial and business transactions.
What is Interoperability Testing?
Interoperability testing services is a form of non-functional testing to achieve and maintain interoperability characteristics in the system. This form of testing is done to ensure end-to-end functionality between two interacted systems based on their specified standards and protocols. Moreover, interoperability testing is used to verify and validate and data loss, incorrect and unreliable operations, and unreliable performance between the two systems.
How to perform Interoperability Testing?
Interoperability testing services can be carried out through the following steps:
- In the first step, proper planning and strategy need to be define and describe. The planning and strategy involves understanding of each application present in the network, including the behavior, response, functionalities and input taken, output generated of each and every application. Thus, the network of applications must be considered as one single unit.
- Implementing certain approaches and techniques like requirement traceability matric to map each requirement with that to test case, and thereby eliminating the scope of any unvisited requirement. Test plans and test cases are derived and developed.
- Executing interoperability testing services with the following activities of logging the defects, correcting the defects, retesting and regression testing after applying the necessary patches.
- Evaluating the test results with respect to RTM, to make sure the complete coverage of the requirements and no requirements has been left out.
- Documenting and reviewing the approaches, steps and practices used in the testing, to further enhance the testing process so as to get accurate and quality results.
Challenges faced in the Interoperability Testing of the Application
- Testing all the applications generates a good amount of possible combinations which are quite difficult to test.
- Differences between the environment where application is being developed and where it is installed might affect the testing, in case any of the environments goes down.
- Different environment issue also needs unique test strategy to involve the need and features of both the environment.
- Applications will be connected in network, thus adding network complexity to it would make the task of testing even more difficult.
- Root cause analysis, if defect is identified.
Solutions to the Challenges in Interoperability Testing
- Testing techniques and approaches like orthogonal array testing (OATS), cause effect graph, equivalence partitioning, bva and other similar approaches may prove beneficial in mapping the requirements independently with that to test cases so as to provide and ensure maximum test coverage.
- Going through the past information and data to study and analyze the conditions under which system crashes or breakdown and to estimate in how much it recovers from failure.
- Making use of the above stated study to prepare proper plan and strategy.
Interoperability testing services is not at all an easy task to execute, but with the proper planning and strategy along with the information, data and experience gained from the past, interoperability testing guarantees the system’s interoperability quality to interact uninterruptedly and independently with other systems and applications.
