  • Unit testing
  • Development testing
  • Integration testing
  • Performance testing
  • User acceptance testing
  • Regression testing

Q4. What is unit testing in SAP?

Ans: Unit testing is done at the transaction level that related to configuration. For example customer master data, vendor data, purchase orders creation and so on. It focus on master record, transactions, roles and profiles.

Q5. For what purpose development testing is used?

Ans: It is use to test various Reports, workflows, forms and so on. Development team is responsible for executing the development test.

Q6. What is Performance testing?

Ans: It is used to test for determining the time taken to perform the actions. It helps to determine the system to meet and fulfill the service level agreement.

Q7. What is Integration testing?

Ans: After all sap modules are implemented, Integration testing is used to test whether all the posting are working properly that cuts across SAP modules, for e.g order to cash, procure to pay (p2p) and so on.

Q8. Tell me about user acceptance testing?

Ans: User acceptance testing is done at end user level those who are executing applications. They run and test the scenarios if any defects are found, the configuration team members resolve these defects during this test.

Q9. What is regression testing and give one example?

Ans: This is used to test previous working system is not affected by the introduction of new system changes. For example organization bought new company and we have to create one or more company code, after configuration we have tested and it working perfectly. So old configuration does not effect any errors due to new configuration.

Q10. What is manual testing?

Ans: Manual testing is done manually to identify the bugs and errors. It is used to test for data issues, for e.g if the master data has errors, with manual testing tester can rectify the master data errors.

Q11. What is Automated testing?

Ans: Automated testing is used to perform tests based on regular interval of times, with the help of scripts you can specify what needs to tested.

Q12. Explain difference b/w control and control object?

Ans: Control is a object for which we want to do testing, where the control object is purpose of control and assigned at sub process level.

Q13. What is test case?

Ans: Test case is a template that every organization maintains and used to test implemented data during project execution according to the scenarios that test cases are created.

Q14. What are the testing tools can be used to test web shop performance?

Ans: We can use testing tools like load runner and mercury.

Q15. What is SAP?

Ans: SAP is a ERP business software package that designed to integrate all areas of business and it provide solutions for all operations. Read more for about SAP

Q16. Specify types of testing?

Q17. What is Defect prevention?

Ans: It is technique used to find and rectify errors before they effect the development phase.

Q18. What is GUI Testing of SAP Applications

Ans: Test the functionality of your SAP R/3 applications. In minutes you’ll understand the power behind Rational Robot’s Object Testing as you quickly record tests that verify:
Properties of SAP screen controls.
Values in application fields.
Integrity of your business process flow.
Robot lets you record functional tests against your SAP R/3 application, regardless of R/3 hardware platform or database server

Q19. What is Load Testing SAP Applications?

Ans: In executing your business transactions on the Web interface, through integration with the powerful SAP engine, the SAP WAS system creates a highly complex dialog between the client machine and the server.
This complexity is not visible to the user or those in charge of deployment, but it is an important factor when it comes to middleware.
Your load testing tool’s ability to take into account the specific nature of this rich and complex dialog is an essential pre-requisite for performance testing SAP applications. The tool must be capable of automatically and natively handling SAP Web Application Server (WAS) in order to efficiently build scripts that cover all your test cases.
Without fully compliant SAP WAS support, you cannot carry out the full range of tests and run the risk of deploying an application whose behavior under load has not been validated properly – with possibly damaging consequences. These could include slow-downs for users, or even blocked access for some users in high load periods, putting in jeopardy not only the success of the project, but also the company’s entire economic foundations, due to the critical importance of its business services.

Q20. What is Testing Orienting Applications?

Ans: Software Testing is more Oriented to Detecting the defects or often equated to finding bugs. Testing is a process of executing a software system to determine whether it matches its specification and executes in its intended environment under controlled conditions. The controlled conditions should include both normal and abnormal conditions. Testing should intentionally attempt to make things go wrong to determine if things happen when they shouldn’t or things don’t happen when they should.21.What is SAP QA ?

Sap QA: – SAP Application QA involves the entire software development PROCESS – monitoring and improving the process, making sure that any agreed-upon standards and procedures are followed, and ensuring that problems are found and dealt with. It is oriented to ‘prevention’.

Q22. What is SAP implementation lifecycle?

Ans: SAP implementation lifecycle
In the lifecycle of a SAP solution, it is necessary to test the functions and performance of the solution developed by programmers. Work environment with SAP testing, SAP provides an environment for all phases of testing, you can use to test in the following cases:

The implementation of SAP solutions:

  • Integration of new components and business scenarios.
  • Client Development.
  • The function tests for all the functions.
  • Integration testing with other components in the integrated environment.
  • Updates/changes regression testing.
  • Import support programs.

Integration Features and Test Preparation:

  • Creation of manual test cases and automated.
  • Management manual and automated test cases .
  • Creation of test plans.
  • Define and manage a series of tests.

Test execution Phase:

  • Test communication with the test tool extended desktop and Computer Aided Test Tool.
  • Integration test cases and test scripts from non-SAP providers.
  • Assign work lists (probes) for individual testers.

Test Evaluation Phase:

  • continuous improvement vision test and test results.
  • Complete documentation of the testing process into test plans (test cases,descriptions of test cases, test results, notes of test cases, error messages).
  • A detailed evaluation of all test plans in tables and graphs.
  • Export test results of the Office applications.
  • message processing.

Generally testing has two ways, one being, system integration testing, this will be performed by the SAP development team of the product owner, and the second being, the user acceptance testing (UAT) is performed on client’s team in the client’s location. UAT usually performed by the end user to test the solution is working fine.

Q23. What is AWB?. What is its purpose?

Ans: AWB stands for Administrator WorkBench. AWB is a tool for controlling, monitoring and maintaining all the processes connected with data staging and processing in the business information whearhousing.

Q24. What is the significance of ODS in BIW?

Ans: An ODS Object serves to store consolidated and debugged transaction data on a document level (atomic level). It describes a consolidated dataset from one or more InfoSources. This dataset can be analyzed with a BEx Query or InfoSet Query. The data of an ODS Object can be updated with a delta update into InfoCubes and/or other ODS Objects in the same system or across systems. In contrast to multi-dimensional data storage with InfoCubes, the data in ODS Objects is stored in transparent, flat database tables.

Q25. What are the different types of source system?
