How SAP Testing is more lucrative than other testing projects ?

,hile testing any A/T '

0. 1ou ac2uire deep functional knowledge of the A/T. ,ithout

sufficient nowledge of A/T its difficult to test

3. *one your testing skills

As with any $T company ' you move from one pro4ect to another in due

course of time. All the hardwor you did to understand the functionality of

A/T is obsolete in the new pro4ect. This is typically true if you are switching

pro4ects across domains say telecom to healthcare.

$n case of SAP' the functional nowledge you ac2uire is portable and can be

used in other pro4ects. Suppose you are switching 4obs. $n your old company

you were testing billing software for "odafone. ,hat is the liely hood that

the same pro4ect is available in your new company - 5e#t to 6ero.

5ow consider this case. 1ou are switching from SAP Testing pro4ect to

another SAP Testing pro4ect in new company. 1ou instantly recognie the 7/$

' Transaction codes' vanilla business worflows which is a huge advantage.

1ou will need to learn the customiations made by the client but still you

need a deep nowledge of the software.

The biggest advantage as SAP Tester is that due to the deep functional

knowledge you acuire! you can easily become a SAP "unctional#onsultant8 SAP %onsultants are in huge demand 9 they are almost always

on short supply and command premium salaries.

What is meant by SAP implementation?

%onsider this scenario. %ompany A offers 03 annual leaves. %ompany :

offers 3; annual leaves. Salary must be deducted for any employee who uses

0<th

or 30st

annual leave for %ompany A 9 : respectively. This information

must be configured into the SAP system which is nothing but SAP

implementation and configuration$

The SAP vanilla version is powerful but not much useful until it=s customied

and configured as per the business policies' legal stipulations' 9 technicalre2uirements of a company. This process is called SAP implementation. $t

could typically tae a few months to even years.

What is SAP customization?

SAP by far has the highest collection of :usiness Process. :ut sometimes

your internal company processed many not be accurately mapped using the

readily available SAP business transactions.

$n such cases custom code is created using A:AP. It involves code changing

to create functionality that is not available through configuration. This

is nothing but customiations. SAP customiation can also be done to

generate custom reports' programs' or enhancements.

What is maintenance of SAP software?

%nce the SAP system is configured! customi&ed! deployed and made live

' any changes made to the SAP system is termed as (aintenance$ This

could include

• 5ew !eature addition to the SAP System

• :ug !i#es

• SAP >ernel /pdates

• Support Pac 9 Stac /pdates

• &SS note implementation

SAP End to End lifecycle and

corresponding Testing Phases

There are multitude of methodology that can used for SAP implementation

• ASAP $mplementation ( !or initial implementation of SAP systems ' and

porting from legacy systems)

Types of Testing Applicable to SAP

applications

!or SAP applications the common testing performed areB

0. /nit TestingB This part of testing is mostly taen care by the

developers based on their defined unit testing rules as per the

organiations. This is sometimes done by the silful white bo# testers. The

test is done in the development bo#. This is the testing of interfaces'

conversions' enhancement' reports' wor flows and forms(R$%E,!)

developed primarily with A:AP code. Testing of development ob4ect

includes testing for security authoriation' 'data transfer rules'

reconciliations and batch scheduling 4obs. :, (:usiness ,arehouse)

testing is also part of the development tests.

3. Integration TestingB $t is the testing of combined components of a

SAP application to determine if they function together correctly. $t is

typically done in the CA environment and uses realistic test data.

F. Security TestingB To ensure the safety of SAP applications' security

testing is performed. *igh ris areasliesap+portal security' networ

security' operational security' product security' access control and source

code audit for security are tested. This is usually involves the basis'

database' infrastructure' development and test teams.

G. Portal TestingB These techni2ues involve testing the SAP Portals on

different browser and checing business processes

"ow to create a SAP Test Case

?et=s design a test case to change the 5ame of an employee in SAP system

To create an effective test case' you must

• etermine SAP role re2uired to e#ecute the test case

• $dentify the SAP transaction that needs to be e#ecuted for the test case

• Test ata re2uired e#ecuting the test case. etermine whether the

data needs to be created or whether it used by another tester or whether

the data is loced 9 cannot be modified.

• Any Pre+re2uisites

•

Peer review Test cases• %reate positive as well negative scenarios

• %reate detailed Test Steps.

• Test coverage should be robust

• ocument defects in timely manner which is as soon as they are

discovered.

Refer this video' for a guideline on how to change SAP $nfotype

The test case designed for this is as follows +

Important 2ote

SAP is a humungous system with endless variations. $ts neither feasible nor

cost+effective to chec all possible variations and combinations of test

parameter inputs in SAP system.

As in above e#ample ' a tester could have verified change in ?ast 5ame' ate

of :irth' Address' Pin %ode' %ity ' State' %ountry' change in permanent '

temporary' wor address etc.

A Tester needs to adopt strategies reduce the number of test cases without

sacrificing coverage. E#amples of such strategies include boundary value

analysis' e2uivalence partitioning 9 orthogonal arrays.

Automated Testing of SAP Applications

Testing is a huge challenge for colossal system lie SAP. As per recent study

by AS/7' &ver GH customers are concerned about riss due to lac of

comprehensive testing.

Automation has following benefits for SAP applications

0. The chief and most valuable benefit is improved test coverage

3. :etter product 2uality and therefore less production outages. &utages

in SAP productions environments could cost a company millions8

0. Test transactions' reports and scenarios

3. %all :AP$s and function modules

Performance testing of SAP applications is done to chec its speed!

scalability and stability. Performance Testing SAP helps with

• %onform with service+level agreements (S?As).

• &ptimie software configuration settings.• Reduce overspending on hardware

• %ertify that the system will not crash or fail during seasonal high load

and help avoid corresponding financiallosses.

application being tested. :elow is a list of SAP performance test tools andtheir application areas
