1. Design IoT application testing process
A QA process manager is assigned as early as the requirements specification stages to ensure all IoT functional requirements are designed in a highly testable way. Typically, the requirements are drawn in the form of user stories.
The QA process manager should then decide upon the deployed QA team and the IoT development team’s degree of interdependencies and mutual collaboration required for ensuring relevant test cases’ prioritization, efficient defects management, and regression testing execution.
Then, the QA process manager should possibly and carefully consider all possible testing risks and design a mitigation plan for the project. The probable risks there can be are:
- Non-scalable, incomplete, and improperly configured IoT test environment that’s not fully reflecting the hardware configurations, lacking simulators or virtualization tools.
- Improper test automation frameworks’ choice and configuration.
- Lack of IoT testing talents to create and execute test cases addressing potential IoT-specific quality issues
2. Preparing for IoT testing
Preparation for the IoT application testing process differs according to the sourcing model opted for in-house testing or outsourced testing.
- Preparing for in-house IoT testing
The assigned QA manager designs an overall IoT test strategy and plan, including effort estimation. As an IoT system’s architecture is prone to changes, the QA manager needs to regularly revise and update the test artifacts accordingly.
Then, the manager assembles an IoT testing team or teams.
It, however, may require several testing teams to cater to different IoT application modules. The actual number of testing teams deployed will depend mostly on the application’s architecture and complexity.
Besides saving time- and data-intensive resources, alongside recurring repetitive test cases execution, an IoT testing project requires a balance of both manual and automated testing. A separate team should be deployed to take over automated testing.
Automation integration and regression testing with critical functional test cases, along with performance testing are always inherently automated. Still, IoT security, usability, and the majority of functional test cases are performed manually.
