Problem statement
Problem Statement

  • Numerous configuration changes, patches, enhancements and new product introductions were being migrated to production on a weekly basis.

  • The knowledge to do end to end test does not exist with one individual.

  • Some of the business processes had numerous steps and dependencies making those processes very complex to test.

  • The high growth of the company and the volume of changes compromised the breadth of testing

  • The manual testing processes did not have adequate audit trail to satisfy the SOX compliance needs and put a very heavy strain on the already stretched IT staff


Objective production control
Objective Production Control

  • Establish QA as a critical part of the overall IT governance process

  • Establish a central repository of interconnected and stand alone business functions that will need to be tested as part of the QA process

  • Establish Integrated test data management

  • Automate the testing process to increase the breadth of testing and reduce the burden on IT staff

  • Ensure that the automated testing process generates adequate audit trail to meet the SOX compliance requirements

  • Ensure that the solution implemented is both scalable and low maintenance


Solutions
Solutions

  • Marvell decided to implement the Entegration Attest Test management console.

  • The Entegration Attest is a portal test console that is built to specifically address the testing needs of Oracle E-Business suite.

  • Entegration Attest helped us address our objectives.

    • Maintain a test script repository

    • Automate the test process

    • Generate Audit trail

    • Flexibility and scalability

  • Entegration Attest uses the industry leader Mercury’s Quick Test Professional (QTP) as the execution engine.

Results
Results

  • A comprehensive QA process was established for Marvell. All changes that needed to be implemented in production first needed to be implemented in a QA environment. Unless all tests passed, the code was not approved to migrate to production. This was established as part of the overall IT governance process.

  • A comprehensive test script library of over 85 test scripts covering all the major business process was created to support the above process

  • What would take one week to test now takes six hours


Continued
Continued …

  • This solution allows us to test the applications using the same user and responsibility as in production without having to worry about maintaining the scripts for menu changes.

  • There is complete audit trail for the tests executed with screen shots and time stamps

  • The Entegration Attest is the single user interface for managing the tests and viewing test results.


Lessons learnt
Lessons Learnt

  • Planning is a key to success.

  • A phased implementation approach proved very beneficial to us.

  • Do not expect 100% automation. Certain processes will still continue to be tested manually. Be sure to clearly identify processes that will lend themselves best to automated testing.

  • Identify the Key Users or BSA for detail information and make sure they are engaged from start to finish

  • Good and effective communication between QA functions and BSA on process changes

  • Prepare to make a small investment in maintenance of your scripts. Changes in business processes may require some changes in the test scripts
