When it comes to performance testing SAP applications, even seasoned project managers can face unexpected challenges. Overlooking key steps in test execution can lead to significant issues down the line.
In this article, we’ll take a focused look at the top five common SAP testing mistakes and practical ways to avoid them.
1. Not planning with an SAP performance testing overview
A detailed SAP performance testing overview helps you make sure your tests cover all parts of the SAP solutions you’re working on, confirming that each part functions correctly for your enterprise resource planning tasks.
Here’s a clearer breakdown of the steps you should take:
Get to know the SAP system: It’s important to really understand the SAP system you’re working with. This means looking into the server, the applications, and how they’re used in your business.
Figure out what to test: Decide exactly what parts of the system you need to test. This might be the user interface or the processes running in the background.
Focus on what’s important for your business: Identify the parts of your business that heavily rely on the SAP system and make sure they’re included in your tests.
Make sure you have the tools you need: For effective testing, you’ll need specific tools, especially for load testing and checking how the system handles data input.
Set your goals: Be clear about what you want from this testing. Are you looking to improve speed, stability, or maybe both?
Test with different scenarios: Use a variety of test data to mimic real-life situations. This helps you see how the system will perform under different conditions.
2. Overlooking the need for variable test data in SAP batch input tests
When you’re running SAP batch input tests, it’s easy to fall into the routine of using the same set of data. However, this approach can miss problems that only show up under different conditions.
Here’s how to make sure your testing reflects real-world use and provides valuable insights:
Use different kinds of data: When you’re doing SAP batch input tests, don’t stick to just one set of data. Mix it up. Use different values to test how the SAP applications react. This helps you spot problems that you wouldn’t see if you only used the same data every time.
Mimic real user behavior: Think about how people actually use the system. They might enter data in various ways, sometimes even making mistakes. Include these kinds of variations in your test data. This way, you can check if the system can handle these real-life scenarios.
Keep your test data up to date: Don’t just set your test scenarios once and forget about them. Update the data you’re using regularly. This approach helps you find issues that might pop up with new types of data that weren’t in your original test set.
Automate the process if you can: If there are tools available that can create varied test data for you, use them. It’ll save you a lot of time and effort. Plus, it ensures that you’re covering a wide range of test scenarios, which makes your testing more thorough.
3. Misconfiguring the SAP GUI client during test creation
Getting the SAP GUI client setup right will be your direct line into how the SAP system works from a user’s perspective.
Here’s what you need to keep in mind to get informative performance test results:
Make the SAP GUI client look like what users see: Set up the SAP GUI client so it closely resembles the actual user environment. This means getting the screen layouts, data entry fields, and transaction workflows to match what users encounter in their daily work.
Go over your settings carefully: Before jumping into testing, take the time to review all the settings in the SAP GUI client. This step is key to spotting any wrong configurations that might throw off your test results.
Try different user scenarios: Remember, not all users will have the same setup. Some might use different versions or have unique settings. So, test the SAP GUI client on various setups to make sure you’re covering all possible user experiences.
Keep a record of your setup: Document how you’ve configured the SAP GUI client. This is really helpful for future reference, whether it’s for your own use or for other team members who might conduct tests later.
Properly setting up the SAP GUI client means you’re testing in a way that’s true to what users will experience. This leads to more reliable test results and, ultimately, SAP applications that perform well when they go live
4. Under-resourcing for SAP load testing
Getting SAP load testing right means making sure you have the resources to test the system as if it were under the heavy demand of a normal working day. You want to find and fix any performance issues now, not when they can disrupt business processes.
To ensure your SAP performance tests are up to the task:
Allocate enough virtual users: Have a number of virtual users that closely represent your actual user base. This helps in creating a realistic testing scenario, mirroring real-life usage.
Mimic real user loads: Aim to replicate the kind of demand your SAP system will face in everyday operations. Your testing setup should be robust enough to handle this load smoothly, which helps you identify any potential performance bottlenecks.
Monitor SAP server performance: Keep a close watch on the server’s performance throughout the testing process. Look out for any signs of stress, like slowdowns or crashes, as these are critical to address before going live.
Test with business operations in mind: The SAP system is there to support real business activities. Make sure your load testing realistically reflects the key transactions and operations that are vital for your business.
Plan for peak times: Consider the times when your system will be under maximum stress, such as during end-of-month reporting or high-volume sales periods. Tailor your tests to these scenarios to ensure your system can handle these peak loads.
5. Skipping SAP load testing altogether
Skipping SAP load testing can lead to serious oversights. This part of testing is key to understanding how your SAP system will perform when it’s under the most pressure. Here’s what you need to focus on to ensure your system is up to the task:
Make load testing a key part of your plan: You need to see how your system does when lots of users are on it at the same time. This tells you how much it can handle and how tough it is.
Use real-life scenarios in your tests: Testing with data that changes and feels real can show problems that you wouldn’t see with just static, unchanging data. This step is super important to really understand how your system will perform.
Find and fix any slow spots: After you do your tests, look at the data to find any parts of the system that aren’t working well. Work on these areas to make the whole system run better.
Test, adjust, and test again: Keep testing over and over, especially after you make changes based on what you found in earlier tests. This helps make sure your system can consistently handle the load.
Including SAP load testing as a standard part of your performance testing ensures that you get a complete picture of how the SAP system will perform. This leads to more reliable SAP solutions and smoother business operations when you go live.
In summary
Avoiding these common mistakes involves careful preparation, a deep understanding of the SAP system, and a commitment to detailed testing. By focusing on these areas, you can ensure that the SAP solutions effectively support the business processes they’re intended for, leading to successful business operations and satisfied stakeholders.
