1.What is the use of SAP Testing?
SAP Testing is about testing the functionality of above SAP modules and to ensure that they perform as per the configuration.
2.What is SAP TAO?
SAP TAO is an automation tool to generate test cases for end-to-end scenarios for SAP applications. Apart from this, there are various other Automation testing tools for SAP testing like HP QTP, and ECATT, etc. that can be used.
3.Why do we perform SAP testing in company?
Here is a list of key reasons why SAP testing is performed and why it is an important function in the growth of an organization –
System Validation – SAP Testing involves complete end-to-end testing and validation of all SAP modules in SAP ERP environment.
Quality and Revenue – SAP Testing is an output-based testing and not like conventional testing methods which are input-based. It ensures the quality of SAP system and also focuses on revenue and cost of the organization.
Cost and Predictability – SAP Testing involves reducing the SAP development costs and improve predictability.
Compliance Requirement – SAP Testing ensures that the SAP implementation is meeting the new compliance requirements in a specific organization and all the modules are working as per the expected configuration.
New Implementation and Configuration Changes – There are different types of changes implemented in a SAP system, like patches and fixes, new implementation, configurational changes. Therefore, SAP testing ensures that all the modules are performing as per requirement in this dynamic system environment.
Integration – SAP testing is performed to test various reports, data flows and work flows, GUI forms, etc. It is used to check system integration between different modules. For example, if an order posting is done that requires an action in Sales and Distribution, MM and FICO, then SAP testing checks the integration between these systems.
Performance – It is also used to ensure if the system will be able to meet the Service Level agreements, time taken by system to perform specific actions, performance of the system, etc.
4.What is Integration Testing?
In this testing, multiple systems are combined together to test the output of the integrated system.
5.What is Stress Testing?
In this testing, the system is put into stress beyond its specification to check when it fails.
6.What is Unit Testing?
It is a type of white-box testing that involves testing a single unit or group of units.
7.What is Beta Testing?
The aim of beta testing is to cover unexpected errors. It falls under the class of black-box testing. It is performed by releasing the pre-version of the final product, called Beta.
8.What is ETL Testing?
ETL testing is performed to ensure if data is correctly extracted, transformed, and loaded from a source system to a target system.
9.What is Manual Testing?
Manual testing means you are testing a software manually without using any automated tools or any script. In this type of testing, the tester takes over the role of an end-user and tests the software to identify bugs or any unexpected behavior.
There are different stages of a manual testing. They are – unit testing, integration testing, system testing, and user acceptance testing.
10.What is Automation Testing? How it is different from Manual Testing?
In Automation testing, the tester writes the scripts and uses software tools to test the product. This process involves the automation of a manual process. Automation testing includes re-running the testcases multiple times that were performed manually.
Automation testing is also used to test the application from load, performance, and stress purpose. It is used to increase the coverage of test. Automation testing improves the accuracy and saves time and money in comparison to manual testing.
11.What are the different software Testing tools?
HP Quick Test Professional (QTP)
12.What is the meaning of STLC? Why do we use STLC?
Software Testing Life Cycle (STLC) consists of all the steps that are performed in a specific way to ensure that quality goals are met and each step has specific goals and deliverables.
STLC is used to improve the quality of a software product and to make it capable to meet the business requirements to achieve certain goals.
13.What are the different stages under Software Testing Life Cycle?
The different stages that come under Software Testing Life Cycle are as follows –
Test Design Phase
Test Execution Phase
Test Closure Phase
14.Provide an example of Unit and System testing in SAP testing?
Suppose the task is to create a sales order and save it. To perform unit testing for this task, the tester should know that the sales order can be saved using the SAP organization elements like customer master data, partner functions, material master data, company code, credit control area, sales organization, etc.
In ABAP development, Unit testing can be performed to check if a report can be created from developer-generated data. It requires assistance from the domain expert.
If you say a cash flow for a quotation in an organization would show that a quote can be used to create a sales order, a delivery can be created and processed from the order, the delivery can be billed, the billing released to accounting, and a customer payment applied against the accounting invoice.
15.What is SAP Security and Authorization Testing?
Security and Authorizations Testing is used to ensure that users are only able to execute transactions and access appropriate data that is relevant to their project.
As with the implementation of Security standards, this is really important to test if security and authorization is placed in a system. Test IDs for job roles are created and used to both confirm what a user can do and what a user cannot do.
16.What is SAP Cutover Testing?
SAP Cutover Testing
Cutover testing is usually performed once in a project lifecycle. Here a full-scale execution is done of all the tasks involved to extract data from legacy systems. Then, to perform any kind of data conversion, load the results into the SAP system and fully validate the results, including a user sign-off.
17.What is OPA?
18.What is Screen Flow Logic?
Screen flow logic in SAP Testing is like an ABAP code and it is used to contain the processing blocks. It contains the procedural part of the screen. It is created in screen painter and this screen painter is similar to an ABAP editor.
19.What is Load Testing?
In Load Testing, the tester applies maximum load on a system, either online users or periodic batch processing, and identifies whether the system is capable enough to handle the load. If not, it finds out the steps needed to improve performance.
20.What is System Performance Testing?
Performance testing checks the following aspects –
Whether the system response time is acceptable as per the business requirement
Whether periodic processes are running within permissible time,
Whether the expected concurrent user load can be supported
Performance testing identifies bottlenecks and coding inefficiencies in the SAP system. It is not likely that system performance tuning is perfectly set up and the program is running with optimized code.
21.What is SAP Interface Testing?
Interface testing ensures that a business process on a SAP system runs automatically, the events are triggered, and the results are transferred to the receiver system. Interface testing involves execution on the sending system followed by automatic generation of the interface output, and then the receiving system consuming that file and proving that a business process continues on the receiver.
Ideally, interface testing involves larger testing activities as a project progresses. Interface testing shows that triggering works, the data selection is accurate and complete, data transfer is successful, and the receiver is able to consume the sent data.
22.Is it possible that changing one module can also effect other modules of your SAP implementation? How?
Suppose you have to create a Sales Order in Sales and Distribution (SD) module. Here, you first need to enter the transaction code(e.g., Transaction Code VA01). Next, check the stock of the item in Inventory module and check the credit limit available on Customer profile in Customer Relationship Module. It shows that all these modules are interdependent; if you customize any of these modules, it will affect the related ERP system.
23.Could you provide QTP steps to perform testing for the above scenario?
To perform SAP testing for the above example, follow the steps given below –
The first step is to install HP QTP tool and to install necessary plug-ins within QTP to make it compatible to connect to ERP system.
The next step is to use HP Quality Center (QC) to develop the test plan and then to convert test plan design to Test Scripts. These test plans can be converted to scripts using HP QTP.
Next, record the R/3 GUI screen of SAP system for SD module while creating Sales Order or creating PR in MM.
After you are done with the recording in QTP tool, create a script in VB.
SAPGuiSession(“Session”).SAPGuiWindow(“SAP Easy Access – User”).SAPGuiOKCode(“OKCode”).Set “/nVA01”
SAPGuiSession(“Session”).SAPGuiWindow(“SAP Easy Access – User”). SendKey ENTER
You can also add different parameters and customizations as per your requirement.
24.What are the important points that you should consider while performing Interface Testing?
SAP Interface testing is purely dependent on the operations and organizational processes. While performing SAP Interface Testing, you need to consider the following key points –
25.What is the purpose of using SAP Interface and what business scenarios are processed by the interface?
Check if the Interface is processing all business scenarios accurately as per the test strategy.
To perform Interface testing, the best practice is to start with performing Unit testing.
You have to check if the outbound interface is alright, which means that it ensures to perform file meeting specifications in terms of layout, etc.
You have to check if the inbound interface is okay. Check if it is reading the file correctly and if it is performing the correct steps in the target system.
26.What is Test Case?
SAP test-cases are required to perform a check on the installation and configuration of the SAP system, any new implementation, multi-language and device testing, intranet testing, real-time testing, etc.
27.Could you provide functional test cases to test a SAP SD system?
To create a SAP test-case, you can pass input data (correct and Incorrect and see the outcome) –
Correct Input Data
Order Date 01/01/2016, Order Type Sales Order
Expiry Date 15/01/2016, Shipping Date 10/01/2016,
Select Payment Due Date 10/01/2015, Item Qty 10, etc.
Incorrect Input Data
Order Date 01/01/2017, Order Type Sales Order
Expiry Date 15/01/2017, Shipping Date 10/01/2017,
Select Payment Due Date 10/01/2017, Item Qty 0, etc.
Output Data – With Correct Data
Order is successfully saved in SAP module and invoiced.
Next is Packing slip number.
Next is Shipping Order number, etc.
Output Data – With incorrect Data
Error message for incorrect data input. Text message for incorrect input data should be defined in the system.
Packing List#, etc.
