Comprehensive Testing Strategy to handle Oracle EBS to Oracle Cloud Migration Testing

Comprehensive Testing Strategy to handle Oracle EBS to Oracle Cloud Migration Testing

August 23, 2021

Undoubtedly, there are numerous benefits of migration from Oracle EBS to Oracle Cloud such as low cost of ownership, continuous delivery, updated versions are available sooner than ever, access to modern features and functionalities, with continuous innovation. However, the major slowness in any lifecycle could be testing if started without an automated test strategy and execution plan exceeding in costs, timelines, and resource utilization.  You can keep your pre, post, and in-migration surprises at a minimum by evaluating your testing strategy. At every step of your Oracle EBS to Oracle Cloud migration journey, there are various technical aspects that must be considered to implement an effective continuous testing strategy.

Prioritize, and Systematize Features to be Tested

Prioritization is often the missing ingredient in the recipe for testing "early and often”. You can’t test everything that only slows down your testing process. Determine which tests "fit right" in automated pipelines, find high-value tests that focus on business risk and the main paths that customers/users actually follow.

An Absolute Test Automation Strategy document for Oracle EBS to Oracle Cloud migration by OpKey provides you a list of recommended migration test cases to ensure maximum test coverage for the migration testing.

In this blog, we’ll show you a short glimpse of all the activities involved in testing, the approach of testing, testing areas to focus on, and the recommended testing approach that will drive you to a Risk-free Oracle EBS to Cloud migration.

The Basics of Application Migration Testing

Pre-migration testing – Create configuration testing suites to test the Customizations moved. Customizations could be configurable/non-configurable Oracle Cloud components.

Migration testing – Testing types that fall under this phase go like i) Configuration Testing ii) Data Validation Testing.

Post-migration testing – This phase includes i) Functional testing ii) Integration testing iii) User Acceptance Test (UAT) iv) Security Validation v) Report Validation.

What to Test When Migrating Your Oracle E-Business Suite to Oracle Cloud?

Functional Validation – Cloud readiness or functional validation helps QA teams to access production readiness of migrated applications. It is recommended to verify if various aspects of the migrated applications are performing as per SLAs. To ensure effective Oracle Cloud migration, QA teams need to validate Oracle Cloud service functions and perform end-to-end application function validation. Given below some of the test cases to perform functional validation of Oracle Cloud Apps:-Smoke test to ensure point to point interfaces

  • Smoke test to ensure point to point interfaces
  • Key business processes and Oracle Cloud Apps are intact
  • Service integration with other applications
  • Page layout and object references are working as expected
  • Cross-platform compatibility is ensured

Integration Testing – Post Oracle Cloud migration, QA teams need to perform integration testing to ensure that apps have been integrated seamlessly with the new infrastructure and other third-party applications. QA teams need to check whether or not APIs and libraries are still working.

To ensure seamless integration testing

  • What interfaces and systems need to be covered while planning for integration testing?
  • Detect coordination problems in Oracle cloud environment to ensure that apps are well configured with cloud environment

Security Testing – Although Oracle Cloud comes with advanced security technologies, enterprises still need to confirm that the data and network environment are still safe post-migration. QA teams need to develop an effective security testing plan that includes penetration testing, security audits, and vulnerability scanning to ensure that sensitive data is stored, used, & transmitted as per compliance requirements. QA teams need to ensure that only authorized users can access data.

Performance Testing – To ensure that customers and end-users get at least the same level of performance as before the migration, performance testing is required. To ensure this

  • Identify and document business transactions and application’s end-to-end flow
  • Identify business SLAs for the business transactions

Report Validation – Regulatory auditors review validation projects by reviewing the summary report. So, summarize the project with a final Report Validation in such a way that it should reflect the relative complexity, business use, and regulatory risk of the system.

Concluding Remark

A successful Oracle Cloud migration requires thorough testing with different scenarios and test data comprehended by demands of continuous testing of system processes to identify and fix flaws and ensure quality reporting and decision making. In the time where the service, manufacturing, or retail all industries have highly configurable dynamic and customized processes of End to End transactions, automated testing is the only saving grace to validate all the business processes with combinations required to be validated in the pre/post phase of migration testing.
