How to Test SAP Applications

SAP is a complex environment but one that is essential for managing companies effectively. The software simply cannot encounter problems and failures, as these could have detrimental effects on business operations. This is why performance testing of SAP applications is absolutely essential and should be carried out on a regular basis. Thanks to NeoLoad and automated performance testing, you can deploy SAP applications with minimal hassle while still reducing the long-term cost of testing.

Why Conduct SAP Performance Testing?

Performance testing verifies the speed, stability and scalability of your SAP applications. The main reasons for performance testing SAP systems are to:

  • Ensure that the SAP application can sustain the expected number of simultaneous users
  • Validate that the SAP application is operating as fast as it should be
  • Understand how well the SAP application is performing within the current infrastructure at the current load, and the maximum number of users the system can handle
  • Determine the optimum infrastructure to operate the SAP system
  • Optimize software configuration parameters
  • Ensure that the various isolated units of an SAP system perform properly as as whole
  • Benchmark system performance, especially when migrating to cloud-based applications 
  • To ensure code changes, or changes to microservices used in a cloud environment meet performance SLOs, do continuous performance testing

S/4 HANA, the next-generation successor to SAP R/3, promises businesses greater simplification, increased efficiency and the ability to handle more complex problems. However, migration to  S/4 HANA requires that the supported applications be designed in an optimal way. That’s why it’s important to test the performance of S/4 HANA applications both before migrating to S/4 HANA and after migration.

SAP Performance Testing: The V-Model

One of the most effective SAP testing models is the V test methodology, which focuses on parallel testing, repurposing efforts and multiple iterations.

The V-model begins SAP testing as early as possible, before the end of coding, in parallel with development activities In a conventional waterfall testing model, testing happens quite late in the development cycle – making it difficult to go back and test processes completed in the early stages of development. This is where the V-model approach to continuous testing throughout the development process can be a real differentiator. 

In this testing method, test activities correspond to equivalent development activities:

  • Unit tests correspond to unit design
  • Integration tests correspond to system design

Everything converges within the V-model down to coding. The left-hand side of the model focuses on the individual software components that need to be designed, while the right side tests each of those components before moving down the model to the next element.

Because each phase focuses on testing requirements against overall objectives, the V-model approach provides comprehensive test coverage. It also enables easier extraction of testing criteria at every stage of development.

Design Your First SAP Testing Scenario

To verify the installation and configuration of an SAP system before implementation, you need to create a testing scenario. This must be as realistic as possible, covering as much of the software’s scope as possible, so it’s important to define use cases and conditions of use of SAP within the company beforehand.

To design effective and realistic testing scenarios, you should:

  • Determine the SAP role  required to run specific testing scenarios
  • Determine the SAP transaction you want to execute in each testing scenario
  • Collect or create the necessary test data for each test 
  • Define the characteristics of testing scenario, such as status, priority, sensitivity, owner, keywords, schedule and classification
  • Identify all prerequisites to make tests realistic
  • Conduct a peer review of use cases
  • Create positive and negative scenarios
  • Check that all essential steps of testing are detailed and well thought out to ensure no bugs will affect testing

During testing, all failures should be documented as soon as they occur. This is the best way to determine the cause of failures to more effectively detect the origin of problems.

Automating SAP Testing

Given the huge breadth and depth of an SAP system, SAP testing is complex and can be quite difficult. Failure to perform comprehensive testing exposes your system to high risks of inefficiency or failure, so it’s important to ensure that testing processes are robust. Manual testing can be time-consuming and sometimes leads to inconsistent results, which is where automated testing can help.

In automated testing, teams still create the necessary scripts but use automated tools to conduct the testing itself. This saves a significant amount of time as well as helps to improve the accuracy of testing.

Benefits of using automated SAP testing tools include:

  • Improved test coverage
  • Improved product quality (which minimizes production stoppages)
  • Reduced workload in subsequent release cycles

In short, it’s the best way to balance the need to ensure quality and the imperative to accelerate development timeframes.
