SAP is a leading software ERP and CRM solution developed in Germany and utilized by a number of mostly large corporations around the world to automate their ERP and CRM processes. All the business processes for most of the industries are accommodated for and can be configured within SAP. Certainly there will be a lot of testing that will go along with all these configurations; However, eventually SAP will allow almost full automation of your business processes. In a technical term though, it is nothing but a software that requires development, testing, release; That has to meet a certain level of quality and be built by a number of requirements. SAP testing is a process of testing and assessing the quality of the SAP implementation for an organization. SAP has a number of different software modules (Procure to Pay, Order to Cash, Financial Accounting and Controlling, Production Planning, Material Management, Sales and Distribution, Human Resources) etc.. each of which is a sophisticated software written using proprietary code. Testing SAP solutions can be both manual and automated testing. Most of the time during the testing, the testers should understand the structure for SAP to be able to efficiently test, there are also cases, specifically for SAP test automation, when testers should have a knowledge of ABAP which is a language that this SAP was developed on. Whether it’s manual or automation testing of SAP software, it is usually very interesting and exciting work that involves not only technical challenges but also full understanding of business process, data flows and integration.
As was mentioned in the first paragraph testing SAP software is almost no different than testing any other software. Therefore most of the testing types apply for SAP testing as well.
Unit Testing: Unit testing is usually the responsibility of a developer and it includes writing test harnesses for ensuring the classes and methods in the code return the expected result.
Integration Testing: Integration Testing for SAP is ensuring that SAP software is integrated with any other software systems used in the business process.
Functional Testing: Functional Testing is making sure that systems is functioning per the business and technical requirements. The software testers will need to create test cases to map them to the requirement and test every module individually as long as when they are integrated together. Functional testing covers testing all features and functions across all possible modules and services.
Interface Testing: There are number of different interfaces within SAP. Each usually services it’s own business goal. All can be configured differently and have to be tested individually.
Performance & Load Testing:Performance & Load testing is done to ensure that the system can meet performance benchmarks under different loads. For example: if it takes 10 seconds to load a screen with one user using the system this number should scale up accordingly and not increase dramatically even if the user base increases dramatically.
There are other types of testing that may not be as popular but are totally applicable to various individual SAP implementations.
Since SAP is a global product and available in different languages Localization Testing becomes an integral role of a System Test plan.
SAP Testing TAO (Test Acceleration and Optimization) a tool that is used to develop test automation in SAP modules. SAP Testing TAO (Test Acceleration and Optimization) is a tool used to perform automated testing of SAP systems. TAO allows quality assurance department to test better and faster by automating test cases that can later be uploaded into test management tool like HP ALM. Tools like Quality Center, QTP can be easily integration with SAP Solution Manager for storage and maintenance of existing and new components. The main benefit of TAO in QA organization is that it allows its user to pre-define and reuse test cases. With the integration component, QA Engineers can login monitor the execution progress through their test case management tool and ensure that testing is continuous. It’s tight integration with SAP Solution Manager allows to monitor all the changes made to the components and ensure timely testing. The drag and drop features allows testing teams to easily learn the tool and significantly increase the throughput of testing. All the bugs found during testing are usually recorded into HP ALM defect module and therefore enabling the ability to trace the requirement – to the test case – to test script – to the bug. There are number of companies and services that will help organizations establish both manual and automated testing of SAP modules
