Summary of tests

Functional testing

For each application or process, addresses the following questions:

• Are there any obvious bugs?

• Do transactions return the same results?

• Will the application break anywhere?

  If you decide to use new functionality:

• Does the release provide the expected functionality?

• What are the limitations of the new features?

Single-user:

• Ad hoc test

• Manual test scripts and cases

• Existing application test suites

Stress testing (benchmarking)

Using very heavy loads, addresses the following questions:

• Are there any code errors related to multiuser loads?

• Is the performance of critical transactions as good or better?

• Is the new release stable under load?

Multiuser:

• Keystroke capture

• Transaction generator

• Production load capture

Integration testing

Ensures that all system components work well together, such as:

• Batch processing

• Online transaction processing (OLTP)

• Decision support systems (DSS) and ad hoc queries

• Operations, including backup, recovery, and dbcc commands

• Sybase products other than Adaptive Server

• Third-party products

Test suite models all system components

End-user acceptance testing

Executes acceptance tests specific to the environment. Also covers functions not prioritized into earlier stages.

Standard acceptance tests

Final migration plan testing

• Ensure that you are fully prepared by walking through the upgrade/migration plan.

• Verify that fallback procedures work.

• Identify and test the contingencies.

Walk through every upgrade step, including fallback strategies
