Hi Gurus.,
Can any one pls say what types of testing done in SAP and in which phases testing is done in ASAP methodology,pls and pls it is very urgent
Thanks in advance

Dear Manam,
Testing mathologies and types: there are 6 types of testings:
1. Unit Testing
2. System Testing
3. System Integration security Testing
4. Performance Testing
5. User Acceptance testing
6. Regression Testing
Unit testing is done in bit and pieces. Like e.g. in SD standard order cycle; we do have 1-create order, then 2-delivery, then 3-transfer order, then 4-PGI and then 5-Invoice. So we will be testing 1,2,3,4 and 5 seperately alone one by one using test cases and test data. We will not be looking and checking/testing any integration between order and delivery; delivery and TO; TO and PGI and then invoice.
Whrereas System testing you will be testing the full cycle with it's integration, and you will be testing using test cases which give a full cyclic test from order to invoice.
Security testing you will be testing different roles and functionalities and will check and signoff.
Performance testing is refered to as how much time / second will take to perform some actions, like e.g. PGI. If BPP defination says 5 seconds for PGI then it should be 5 and not 6 second. Usually it is done using software.
Regression testing is reffered to a test which verfies that some new configuration doesnot adversly impact existing functionality. This will be done on each phase of testing.
User Acceptance Testing: Refers to Customer testing. The UAT will be performed through the execution of predefined business scenarios, which combine various business processes. The user test model is comprised of a sub-set of system integration test cases.
We use different software during testing. Most commonly use are
Test Director: which is used to record requirement, preparing test plan and then recording the progress. We will be incorporating defects that are coming during these testings using different test cases.
Mercury Load Runner: is used for performance testing. This is an automatic tool.
What does the following terms means :
- Technical Unit Testing
- Functional Unit Testing
- IntegrationTesting
- Volume Testing
- Parallel Testing?
Technical Unit Testing= Test of some technical development such as a user exit, custom program, or interface. the test usually consists of a test data set that is processed according to the new program. A successful test only proves the developed code works and that it performed the process as as designed.
Functional Unit Testing= Test of configuration, system settings or a custom development (it may follow the technical unit testing) These usually use actual data or data that is masked but essentially the same as a real data set. A successful test shows that the development or configuration works as designed and the data is accurate as a result.
IntegrationTesting= Testing a process, development or configuration within the context of any other functions that the process, development or functionality will touch or integrate . The test should examine all data involved across all modules and any data indirectly affected. A successful test indicates that the processes work as designed and integrate with other functions without causing any problems in any integrated areas.
Volume Testing= testing a full data set that is either actual or masked to insure that the entire volume does cause system problems such as network transmission problems, system resources issues, or any systemic problem, A successful test indicates that the processes will not slow or crash the system due to a full data set being utilized.
Parallel Testing= Testing the new system or processes with a complete data set while running the same processes in the legacy system. A successful test will show identical results when both the legacy system and new system results are compared.
Do award points if you found them useful.

Hi,
Integration Testing:
The testing of a chain of business processes which flow together and/or cross functional boundaries. Integration testing also involves outputs, interfaces, procedures, organizational design, and security profiles. Its focus is on likely business events and high-impact exceptions.
Unit Testing:
unit testing is a procedure used to validate that individual modules or units of source code are working properly.
Stress testing
Stress testing often refers to tests that put a greater emphasis on robustness, availability, and error handling under a heavy load, than on what would be considered correct behavior under normal circumstances. In particular, the goals of such tests may be to ensure the software doesn't crash in conditions of insufficient computational resources (such as memory or disk space), unusually high concurrency, or denial of service attacks.
Examples:
A web server may be stress tested using scripts, bots, and various denial of service tools to observe the performance of a web site during peak loads.

Hi,
In SAP normally we used Unit testing & Integration testing.
and the following testing are used depends upon the client requirements. or land scape.
acceptance testing
configuration testing
end to end testing
functional testing
performance testing
system testing
system integrity testing

Hi Manam,
We have the following types of testing:
Review & Inspection
Review is of 2 types: table / Peer Review
Testing is boradly classified into 3:
Unit Testing / Integration Testing / Acceptance Testing
Different types of testing we do are:
acceptance testing
black box testing
configuration testing
end to end testing
functional testing
load testing
mutation testing
performance testing
real-time testing
regression testing
stress testing
security testing
system testing
system integrity testing
etc
REWARD POINTS IF IT HELPS
