• Key Aspects: It means the actual testing of disasters and ensuring that the backup applications, recovery procedures as well as failover solutions are appropriate.

7. Availability Testing

• Purpose: Responsible for checking if the status of a given system can support the end users and testers in the agreed levels of service availability.
• Key Aspects: They are system checks, performance trials involving system downtime, and checks and tests of redundant and failover systems.

8. Multi-Tenancy Testing

• Purpose: Ensures that applications that are for the multi-tenant architecture can effectively cater for the tenant’s isolation of data, preferences, and configurations for each user or clients.
• Key Aspects: Mainly revolves around data isolation, performance issues arising from multi-tenancy, a tenant’s ability to secure his own area.

9. API Testing

• Purpose: Checks that APIs (Application Programming Interfaces) are functioning as expected by making sure that the API returns the proper responses to the different requests made to it as well as the manner in which it handles errors.
• Key Aspects: Refers to the process of checking the endpoints, methods, and formats of the data as well as validating the APIs against set requirements and parameters.

10. Network Latency Testing

• Purpose: Determines the latency which is the time taken by data to cross the network and gives the time taken for different phases that may affect the functional of real-time application.
• Key Aspects: This involves testing under different network connection, geographical areas and operational loads with a with a view of evaluating the effects of the network on the user.

11. Data Migration Testing

• Purpose: Translates data well and in full from one system to another at different phases of migration.
• Key Aspects: Consist of data validation and assessment of the data’s accuracy, coherency, and adequacy, as well as the pre- migration, migration, and post- migration impact on application performances.

12. Elasticity Testing

• Purpose: A benchmark used to measure a system’s capacity to adjust the levels of resources needed depending on the usage demands.
• Key Aspects: These are possibilities of emulate several kinds of burden on the networks; to supervise the resource utilization and to check that performance still actual under different burdens.

13. Compliance Testing

• Purpose: Checks that the systems meet the requirement of the regulatory framework, code of practices and legal requirements in the business domain.
• Key Aspects: Concerns itself with security and/or privacy and/or data protection and/or other operational compliance activities, which may well involve paper trails and the creation of documents.

14. User Experience Testing

• Purpose: Determines whether the users of the end product find the application easy to use and easily navigable, thus providing a suitable end-user perception.
• Key Aspects: Refers to the assessment of the layout, user experience, and effectiveness of the site’s interface, namely, how the site interacts with the user; it may rely on users’ reports and tools for testing usability.

15. Interoperability Testing

• Purpose: E2E guarantees that the application interacting effectively with other systems, platforms, and applications of its environment.
• Key Aspects: Possible to mention testing data exchange and system compatibility of work with other operation systems, browsers and with third party service and integration.

Cloud-Based Testing Tools and Services

• Continuous Testing in CI/CD Pipelines: Continuously perform testing on the product through inclusion of automated testing in CI/CD testing. It leverages cloud technologies to carry out the testing life cycle from the beginning to the end.
• Artificial Intelligence and Machine Learning in Testing: To advance the test data management, defect prediction, and test case creation, it is recommended to introduce AI and ML. Such AI/ML tools can be had on cloud platforms and can be integrated into the testing process.
