1 ) Can anyone kindly tell me what types of testing is done in SD Module ?
2 ) Can anyone kindly explain me Sales order cycle End to End?
Can email me any information to firstname.lastname@example.org
Points will be rewarded to helpful answer.
Generally SD Consultant will do Unit testing,Integration testing and some times regression testing to test the changes done in Configuration.
General sales order cycle starts with Inquiry - > Quotation -> Order -> Delivery -> Picking -> Goods Issue - > Billing.
i think this will help u.
Testing: the core team members along with endusers will test whether the postings done in SAP is resulting as per the requirements of the organisation. They will test whether the output documents such as purchase order, invoice document are printed in the required format and showing the correct data.
Unit testingis refer to the module which are going to implement. SD, MM, FICO etc. there will be test script based on that testing will be performed.
Integration testingwill be cross the modules. MM-SD-FICO for example. Integration testing is also called SIT ( System integration testing)
System Integration security Testing
Unit testingis 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.
System testingyou 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
- 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.
I would also note that when a new implementation is being done you will want to conduct at least one cut over test from the old system to the new and you should probably do several.
What kind of testings that are carried out in testing server?
1. Individual Testing ( Individually which we've created)
2. Regressive Testing ( Entire Process)
3. Integration Testing ( Along with other integrated modules)
The 3 types of testing is as follows:-
1. Unit testing (where an individual process relevant to a SD or MM etc is tested)
2. Integration testing (where a process is tested that cuts across all areas of SAP).
3. Stress testing (where lots of transactions are run to see if the system can handle the data)

Unit testing deals with testing a unit as a whole. This would test the interaction of many functions but confine the test within one unit. The exact scope of a unit is left to interpretation. Supporting test code, sometimes called scaffolding, may be necessary to support an individual test. This type of testing is driven by the architecture and implementation teams. This focus is also called black-box testing because only the details of the interface are visible to the test. Limits that are global to a unit are tested here.
In the construction industry, scaffolding is a temporary, easy to assemble and disassemble, frame placed around a building to facilitate the construction of the building. The construction workers first build the scaffolding and then the building. Later the scaffolding is removed, exposing the completed building. Similarly, in software testing, one particular test may need some supporting software. This software establishes an environment around the test. Only when this environment is established can a correct evaluation of the test take place. The scaffolding software may establish state and values for data structures as well as providing dummy external functions for the test. Different scaffolding software may be needed from one test to another test. Scaffolding software rarely is considered part of the system.
Sometimes the scaffolding software becomes larger than the system software being tested. Usually the scaffolding software is not of the same quality as the system software and frequently is quite fragile. A small change in the test may lead to much larger changes in the scaffolding.
Internal and unit testing can be automated with the help of coverage tools. A coverage tool analyzes the source code and generates a test that will execute every alternative thread of execution. It is still up to the programmer to combine these test into meaningful cases to validate the result of each thread of execution. Typically, the coverage tool is used in a slightly different way. First the coverage tool is used to augment the source by placing informational prints after each line of code. Then the testing suite is executed generating an audit trail. This audit trail is analyzed and reports the percent of the total system code executed during the test suite. If the coverage is high and the untested source lines are of low impact to the system's overall quality, then no more additional tests are required.
