could any one brief me about how to do system integration tesing

(SIT), stress and volume tests.

hi Goutam,

Role of SAP Consultant In Testing

1. What is the role of SD Consultant in Testing while implementing the project?

2. What is Unit testing and Integration Testing?

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 testing is 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 testing will be cross the modules. MM-SD-FICO for example. Integration testing is also called SIT ( System integration testing)

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.

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.

Hi Goutam,

Integration testing (sometimes called Integration and Testing, abbreviated I&T) is the phase of software testing in which individual software modules are combined and tested as a group. It follows unit testing and precedes system testing.

Integration testing takes as its input modules that have been unit tested, groups them in larger aggregates, applies tests defined in an integration test plan to those aggregates, and delivers as its output the integrated system ready for system testing.

Purpose

The purpose of integration testing is to verify functional, performance and reliability requirements placed on major design items. These "design items", i.e. assemblages (or groups of units), are exercised through their interfaces using black box testing, success and error cases being simulated via appropriate parameter and data inputs. Simulated usage of shared data areas and inter-process communication is tested and individual subsystems are exercised through their input interface. Test cases are constructed to test that all components within assemblages interact correctly, for example across procedure calls or process activations, and this is done after testing individual modules, i.e. unit testing.

STRESS TEST - Non Functional Testing

Tests the system in the context where quantity or the rate of the input exceeds the Design limit.

Hope these details provides you some clarity. Reward points if it helps you.

Hi,

There are two concept unit testing and integration testing.Say for example in your project modules such as SD,MM,CS,FI,PP are used.So when you do all the customizing for each module,first testing will be done within the each module inteslf.Like in SD we will test all sales order processing upto billing,In MM we will test all the purchasing scenarios and so on.

Once this is successful you will run the whole cycle across all moduls say starting with purcahsing,sales cycles,FI cycle and so on.

So with this we can check if there are any issues.

Reward points if heplful.
